Re: Fixing up my 14ft MFG Niagara. transom rebuild w/pics

Cool so i put the 2 or 3 piece transoem together outside the boat then install. Do i want to glass it together as 1 Piece Then instal and glass to hull and floor. I will probably do this after i get the motor mid season when all the A holes have taken over the water. I ushualy stay away on those days.
Matt
Thanks Mark and everyoen who helped me.

You will want to trial fit each piece, get it as tight as it can be to the sides without being a force fit. You may find that the upper corners have to be pieced in separate to be able to clear the cap.

The reinforced filler referred to above is often referred to as gorilla hair at the body shop supply shop. When you open the can, you'll see why.
Don't try to use the gorilla hair as a finishing filler, also buy some evercoat fine filler for that purpose, just to fill minor imperfections. Seal and prime all filler before paint.

I will soon be doing the same thing to a '66 Niagara I have here, only mine has no cosmetic damage to deal with, only some rotten transom wood.
I may do a poured transom on mine only to make it a truly wood free boat.
Mine has no foam flotation, no wood in the gunwales, and my deck is all fiberglass. The last owner did the same as in yours and added two wood panels to support two metal pedestal seats. I may do something similar only a lot cleaner looking.
My gelcoat was in very nice condition and needed only a minor polishing to bring it back to like new condition.

Yours appears to have had a make shift transom repair done, possibly someone tried to fill in the rotted out area with new wood and filler, and that splash well looks like they tried to glue it or seal it somehow to the transom.
That boat had an aluminum transom cap when new, you will want to make something up to cap the new transom as well. What I did was to go to a local sheetmetal shop that specialized it gutter work and custom aluminum and had them bend me up some 1.55" x 1/4" C channel from .040 aluminum. The result was a near duplicate of the factory aluminum cap.

The crack and loose filler appears to be a poor attempt to repair some old dock or crash damage. One reinforced and filled properly, it will be good as new.

Definitely check out Mark42's pages on his boat, he's been there and has most of the solutions figured out on these boats.

Re: looking into fixing up my 14ft MFG Niagara. Any suggestions

.........(I suggest two layers of 3/4" pressure treated ply that has had a couple of weeks to dry, glued together with either construction adhesive or epoxy)......

Hey Mark (funny we have the same name and similar boats!)- Great advice. You've done a lot more to your MFG than I had to do to mine, apparently. I learn something useful most of the time I read your posts:)

matt9923: You are getting excellent information here.

I personally would not use pressure treated plywood, though. Just my opinion. I would use "fir" AC or BC or even CD with "exposure 1" or "exterior" stamp. Unless they have changed it in the last few years, I am of the opinion that PT plywood is way too corrosive to non-stainless fasteners. If the transom is capped properly like all the instructions indicate, and the two drain-plug ferrules are properly installed, he should not see water enough to rot for 20 years or longer if the plywood is properly sealed. PT is generally made with Southern Yellow Pine veneers; I feel a whole lot better about western fir ply.

I have the same boat, 14', but no splashwell, and no splashwell drains- must have been an option. As far as your seats and floors: I installed 16" steel pedestals (the cheap black ones from K-Mart) in 1995-ish. In fitting them, I was trying to get a sense of spacing in the narrowish beam of the boat, and clearance from the dash- close but not being uncomfortable. So I temporarily screwed them to the floor with #8 stainless oval head wood screws. The floor in the Niagaras are solid fiberglass, and apparently rugged enough that (get this!) believe it or not: I never got around to screwing them down "correctly" but they are still there, same screws, never loosened, never pulled out:eek:. I have taken the pedestals out a few times for various reasons, but still using the same screws. So unless Previous Owner was a complete fool, your floors should be good and solid. I have never seen an MFG Niagara with a bad floor (here in Vermont). I would not cut the floor if you can avoid it. 2002 I filled all the OEM seat mount holes with flush-fitting white vinyl hole plugs from the hardware store, popping them in with 5200. I figured they would last a few years, and replace them if need be, but none have failed!

When I replaced my transom wood, I did it once the wrong way (95-ish), reaped the reward from that :( and then in 2001-ish I cut out the inside fiberglass and fit my pieces in that way. I capped it with glass and resin, and actually installed 1/4" thick 2"x2" aluminum angle over the top of that as a bullet-proof top rail so no wear under the motor yoke clamps. Aluminum cuts nicely with carbide tipped blades on a tablesaw and router if you want to make nice edges. I spent hours polishing and countersinking for #12 stainless screws, and sealed everything with 5200. Yes, that was overkill. That happens to me sometimes:rolleyes:

I took off my plastic windshield and buffed it. I have seen MFGs with flimsy windshields, and others with a sturdy aluminum-framed Taylor Made which is what I have. I laid it on cotton towels, and buffed it with Mirrorglaze Plastic Polishing compound. 2500 rpm and a cotton terry head- don't try this with lamb's wool or synthetics or synthetic blends or chamois because they have too much friction and will melt or otherwise "swirl" the plastic. It is not perfect, but it is acceptable and safe, looks good, no more haze, and didn't require me buying a new one :D

Good luck with your project and pay attention to the info these guys are giving you- great advice, and stuff you can't get from a book.

Mark,

Nice you were able to polish out the windshield. Mine was full of crazing marks and yellowed through. At least I had it to make a template from.

These Niagara boats are just the right size for quick launch and retrieval. We use the heck out of ours. Its in the water every chance I get!

I like the pressure treated ply because I know sooner or later, there will be a leak into the transom. And I don't want all that hard work to go out the window. Nothing wrong with using CDX, but I'll stick with P/T where it might get wet.

Re: Fixing up my 14ft MFG Niagara. transom rebuild w/pics

I will probably go to the lumber yard and pick up a piece of PT 3/4" plywood this weekend and put it in the barn with weight on it but also air flow so it doesn't warp and let it sit for a month or until i am ready to do the transom.
What epoxy and mat do i get can i get any epoxy and mat form napa or autozone? or a boat shop?

Your best bet is probably to buy your supplies online, especially if using epoxy.
I use either JGreer.com or one of the other similar suppliers. Do a web search for epoxy resin and for fiberglass supplies. There are none really close to me that sell reasonable,so I buy mail order. Fiberglasssite is one that comes to mind off hand. For the amount of cloth or mat you will need, you may be able to buy it from a local boat builder or body shop supply.

Re: Fixing up my 14ft MFG Niagara. transom rebuild w/pics

Matt,

Have you decided to use epoxy? If so, and all you are glassing in is the transom, then order a couple of yards of the 1708 biax cloth. It will work well for what you are doing, and you can cut it into 6" strips very easy with a razor knife or scissors. The transom will only need one or two layers tops, and three layers of tabbing.

The 1708 from fiberglasssite is what I used on my hardtop project, so you can see some pics of it being used in the link in the signature below. It has 8 oz chopped strand mat stitched to a 17 oz biaxial fabric. Pretty heavy, and sucks up resin fast, but it is also very versatile. Also, just to do the transom, probably order two of the 1.3 gallon epoxy kits, or 2 gallons of poly resin.

If you order the epoxy and have leftovers, let me know!!!

Re: Fixing up my 14ft MFG Niagara. transom rebuild w/pics

I think i am going epoxy idk why but i hear it stronger so even if i don't to the best job it will still be strong. I think i am getting 635 thin epoxy medium cure time. I'm hoping 1 1/3 gal will be enough. If not ill get a quart or 2 more.

-I will glass the transom together (the 2, 3/4 pieces so it will be 1 glassed together piece) after test fitting each piece and getting everything perfect.

-when it cures ill tab it in. Do i have to let each layer dry before making the next tab layer?

8.9oz Fiberglass E Cloth -

......windshield. Mine was full of crazing marks and yellowed through.......These Niagara boats are just the right size for quick launch and retrieval......

Mine has some crazing, but so little I don't mind it- lucky, I guess.

Yes, mine does retrieve well too. I never even got around to welding on my guide-ons for the trailer I rebuilt; other than a few gale-force days (and a notable day on the Connecticut river once:), loading is easy.

The other thing is that they are fairly light for a fiberglass boat with so much freeboard, and seem to be wicked strong. Nice dry boats and kids don't fall out :) Of course mine are teens now so less important, but 26" from the floor to gunwale is nice to lean against when fishing too.

matt9923 has his work cut out for him- PO didn't plan him any favors! But looks like he is headed in the right direction. Can't wait to see it done.

I missed out on a nearly perfect (!!!) 15'+ Niagara (15'4" I think?) last summer. Couldn't scrape the funds in time, but there was one for sale a town or two over that sold for $1500. Good (too big) trailer, shiny clean boat, clear windshield, and a '94 Yamaha 50hp on it. Must have been stored inside all these years. But alas, went with some cash to dicker with the guy and it was already sold, awaiting pick up.:(

....

It will probably be setting up by the time you get the next batch mixed. So that means you need to wash off any anime blush (sticky wax that forms on surface of epoxy) before applying the next layer. It washes off easy with dish detergent/water and a medium scrub brush. Then hose off and let dry. If the epoxy has not started to harden, then you can add another layer on top of last. Just don't mistake anime blush sticky surface for uncured resin.

Seeing as you are using epoxy, I see no need for the different special fabrics. I would just get some 1708 and use it for everything. From what I read, a special laminating schedule is more important with polyester resin, but not as important with epoxy. And it simplifies things a lot just having to deal with one cloth.

Thanks. 1 1/3 gal resin and 1708 mat is 144.00 shipped and teh 3/4 pt plywood is probably $50. $200 for a new transom....
Seacast is $250 but i think i want to learn how to do this as much as i don't want to.
Thanks for all the help i am sure ill have more questions i'm going to look at the motor now.
The boat needs 100% new electrical system,Battery switches wire ext... previous owner made a wiring hell 1/2 speaker wire 1/2 who knows

Pricing-
motor- 1500-1600
steering- 145
transom- 200
Electrical- 200 (w battery what do you recommend for under $80)
Paint fiberglass work- 50
Boating supply- 50
SO i have some spending to do. I had a box of all the electrical stuff i needed probably $450 worth and someone threw it away!!!

New motor! Oh baby! Don't forget to get the controls and cables, that old Johnson/Evinrude control will just not work.

The new controls will come with 1/2 the wiring the boat will need. After its all installed, it is just a matter of wiring up navagation lights, horn, and any accessories you need.

BTW, NAPA has a nice fuse block with clear plastic for 4 fuses for about $21. Go to NAPA online, shop online, and do a search on fuse block.

Dont toss the old controls and cables. Clean, paint, lube and put on ebay, you can get $50 or more.

Re: Fixing up my 14ft MFG Niagara. transom rebuild w/pics

yes it comes with the controls it has electric tilt/trim. I am buying a new battery for the starter and trolling motor. I think 1 battery will be good for now. I am holding off on the lights and horns and all the fun stuff for now. I'm already over budget. Im getting to the motor and ordering a new steering system. Then ill watch the transom and if I really need to ill do it this season but i hope ill be OK.

Orderd my new uflex steering system.

What do you think about tubing, knee boarding, sking with this boat. After i rebuild the transom of course.
It will be 40hp but the bow will be up an the air I'm thinking. Maybe sand bags in the front.

Matt9923: The bow won't be up in the air. The electric trim will let you control that. I have a 40hp Suzuki which does not have electric trim, but has a pin which allowed me to adjust the trim fairly good. Having electric trim will let you do the same, probably better. The Mariner will be quieter, smoother, more economical, and will probably weigh less than the trusty ol' Johnson. I think the Suzuki saved me about 25 pounds!

You can re-locate the fuel tank under the bow- that is where mine is. 14' Niagara is roomy for its size once you get rid of some of the stuff on the floor. Like putting the fuel tank under the bow:)

I tow a 6' tube with mine. You have to get the tube off to the side and full-throttle it. The boat will plane up with you and a spotter on board before the tube gets fully behind you. Then well-executed S-turns will get the tube planing- keep up the ess's and no worries. >ahem< 6' is probably too big :redface: but once it planes...

Funny story in retrospect, but here's my "dumb boating" story. The boat will probably handle a 50hp OK but it is rated at 45hp max, and the formula they use is probably about right. But MFGs were made back in the days when the HP was rated at the powerhead, before the lower unit gear loss is factored in. I was told HP has been rated at the prop for over 20 years now. So technically I suppose 40hp is max if we follow that logic; don't know the math.

I do know that my MFG topped out 23-24mph with the '64 Johnson 40hp, but that jumped to 32mph on a GPS with the Suzuki 40. Drops to 28-ish mph with the "automatic" trolling plate installed. 32 is screamin in that boat, and fooling around doing dumb-quick turns you can get it to skate pretty bad. Never had that with the Johnson, but the first time out with the Suzuki trimmed right and I learned first hand something I knew but had never experienced. I didn't swamp it but I was pretty sure I was going swimming for a sec. My only stupid boat story.

Forget the sandbag ballast; the Niagara is a great little boat, but it's still a small boat; extra weight is just a performance drain. I bought mine as a stepping-stone boat in 1993 (94?) and liked it so much I still have it!
