Re: Need help with a 1982 Evinrude 10HP that is having lots of problems

You can do that, but the outboard won't be as efficient, and it'll stick down 5" further, and that can lead to unexpected bumps on rocks, etc. You might or might not also get a nice bunch of water trying to get in the back of your boat with the prop that deep. Your boat is fairly large, by the look of it, so you won't be planing with that 10 hp, anyhow, most likely. Most boats with a 20" transom cut down for a short shaft outboard won't plane with a 10 hp. You could run it deeper, I suppose, but for less than $10, you can raise it up and get the maximum possible performance from it.

NOTE: Someone will come here, no doubt, and tell you to raise the outboard even further. They're wrong. Those outboards are meant to run deeper than modern ones, and the 5" lift is correct.

The nice think about the bracket I'm talking about is that you can remove it at any time, if you get a short shaft outboard later on. There will be four holes in your transom, which are easy to seal up with some dowling and some paint.

It's worth the effort, I guarantee.

Great...Sounds good.

Thanks again CAT for all of your help. I really appreciate it.

I will wait for TashasDaddy's reply about the transom Bracket.

Also, do you have any idea where I can get some of the knobs and other parts for such an old motor?

Also do you know why the one knob could be so loose? I did tighten it all the way up and it seems to be holding better but I don't know how it will run in that position.

Ebay is a good source. You can also go over to www.aomci.org and use their free classified ads to ask for what you need. Those guys over there are really good about helping out. Just make a list of what you need and post it there. You'll probably get some quick results.

As for the loose knob, it may be one of the mixture adjustments. If so, the packing is probably bad. A carburetor kit, which you can get here on iboats, will have the packing in it.

Re: Need help with a 1982 Evinrude 10HP that is having lots of problems

OK here i am at your beckon call. you can either do a transom elevator or a jack plate. we are talking about a 10 hp, so a transom elevator is the right solution. it is taking 4 pieces of 1 1/4 inch aluminum angle, sold at home depot near the screws and nails. you put a 2x6 on top of your transom thru bolt it with 4 bolts, then thru bolt thru the transom. i would use 18 inch pieces of aluminum angle. so you need 4 pieces of angle and 10 3/8 bolts& nuts, 20 washers 10 lock washers. get it mounted set the motor and go boating, safely.

Re: Need help with a 1982 Evinrude 10HP that is having lots of problems

Are there any issues/leaking with the bolts that are lower in the transom? Is this setup pretty sturdy? Or do I need to worry about traveling with the motor on the back attached to the transom?

Do I need to treat the 2x6 with and sealer or anything like that?

I am assuming that the top drawing is from the side and the bottom drawing is from above. Is that correct?

Re: Need help with a 1982 Evinrude 10HP that is having lots of problems

couple 3 coats of good ole rustoleum, on the 2x6. use some 3M 4200 in the holes and on the bolts to seal them. is it sturdy, it is as good as your transom is. i have never had a problem towing.

you are correct in the views. need more help just ask.

What is 3M 4200? And is that something I can find at Home Depot?

I might have missed it. I haven't seen anyone mention that that engine requires a 24:1 fuel mix.

Thanks JB...I wasa using 50:1. I will make sure to adjust this. Where did you find tha out?

I think I should invest in a repair manual.

Re: Need help with a 1982 Evinrude 10HP that is having lots of problems

it would be a great investment.

3m-4200 boating stores have it, Home Depot has it some times, as does Lowes. in the caulking Paint Dept.

Re: Need help with a 1982 Evinrude 10HP that is having lots of problems

Here are a couple pictures of my transom and I have a couple of questions to go along with them.

With the metal border on top of the transom will I have problems with the angle sitting flush to the transom? I was thinking of grind the angle a little but I think the would weaken the integrity of the angle.

Also on the inside of the transom there is already a big piece of metal there to help support the transom and motor mounting. Should I go ahead and drill through that was well?

Thanks everyone for your help.

I also attached a picture of my boat, so you can see what I am working with.

Nice looking boat. It'll make a good fishing boat.

Measure the transom thickness at the top. It may be slightly thicker than the 2X6 you'll use for the project. If so, laminate some plywood to it to make it the same thickness as the transom. That will simplify things for you. Put the additional plywood on the inside, rather than the outside.

As an alternative, you can use a plywood laminate, made up of whatever thicknesses are needed to make the whole thing. If you do that, screw and glue them together. You can use Gorilla Glue for this.

In any case, be sure to seal up your wood well. I just use two or three heavy coats of Rustoleum. to do it, and so far it has lasted for about five years. I think there's even a tan Rustoleum color that comes pretty close to your boat color.

You can drill right through the aluminum panels you mentioned. Be sure to use some 3M 4300 sealant to seal the boltholes.
Do use stainless steel hardware on this. It's worth the extra expense.

Re: Need help with a 1982 Evinrude 10HP that is having lots of problems

No problem. I just realized that you're the same guy who was looking for a boat in the Phoenix area. Looks like you found a nice one there. I'll bet you're going to have some fun in that with your family!

As an aside, if it appeals to you, a lot of guys with boats like yours cut out a riser that fills the entire cutaway on the transom. It's the same principle as the smaller riser you're building, but it has a more finished look to it. It's something to consider. You still need the angle bracing, of course.

Also, remember that you can always get rid of your riser if you later find a short-shaft engine you like. That's in favor of just the riser than a complete fill-in piece. Also, if you decide to put a transom-mount trolling motor on the boat, you may want to put it on the lower transom area. If you do remove the riser, a lot of guys plug the bolt holes with hardwood dowels coated with 3M 4200 or 5200, then sand them off flush. It makes a nice repair.

Lots of decisions, but that's boating for you. One other thing: if you can, put the fuel tank up by the middle seat. It's important to keep as much weight forward on a setup like yours. It'll help you get on plane.

Re: Need help with a 1982 Evinrude 10HP that is having lots of problems

Yep, that is me. I found this boat and it is in really good condition. No leaks and very straight.

Just need to get the motor issues ironed out and I will be on my way.

Sure are a lot of options...kind of makes it fun, as long as everything works out alright.

I just found this on ebay:

I wish I had a short shaft like that. Would make things a lot easier.

Re: Need help with a 1982 Evinrude 10HP that is having lots of problems

this is still easy, and cheaper. the ridge should not give you a problem, if it does, just use a couple of large washers on the inside.


it looks like the motor is not center on the transom in the pictures.

red is the brackets, blue is the wood . green thru bolts.

you could actually redrill the 2 top bolts in the Knee Brace and use those hole for the mounts. that would even add more strength. yellow spots.

Re: Need help with a 1982 Evinrude 10HP that is having lots of problems

Ok...I think I have it.

Except Where the dark blue line is, transom goes back about 1.5". So should I put a 2x4(RED) there to make up for space? And maybe add another bolt(GREEN) on each side to help with the 2x4?

Thanks
