Mfg inboard transom

[Bigtrout29]

Hey guys getting ready to start the new transom in my mfg I know epoxy is the way to go but the boat is poly should I go poly or epoxy trying to keep the cost low as I have alot of patches to do any input would be great

Poly is just fine. On my Sea Ray restore I used only poly. That is what the boat was built with so that is what I used. Lasted 40 years with poly and rotted wood, so it will be fine for another 40 plus. When I build my boats I tend to use epoxy. Mainly because the wood in my builds is the structural part, and I just want a thin layer of glass to waterproof. In my opinion it is easier to put a thin layer of glass down with epoxy. I also 'glue' all my joints together in the builds with epoxy. I trust it more for a structural glue in a wood boat build then poly.

Poly is much less cost than epoxy and will work fine .
Got any pics ? We love pics !

I have to go the poly route myself, and actually did as well. It cost less, does the job without any issues what so ever, and will adhere to your original hull as well. Can't say that for epoxy. If you could only see how solid polyester resins and fiberglass material cure up, you would have no issues going that route either. JMHO

Hey quick question does anyone know is the bilge stringers in the mfg run all the way to front of the boat or just in the bilge area

What year and model do you have ?

 

[Bigtrout29]

It is a 84 mfg caprice 19.5 ft bowrider I Delaminated some of it to remove the transom looks like a peice of 3/4 plywood sandwiched between to 2x6s

Hey one more question before I start the rebuild got all the old transom out and starting to sand how much should I sand right down to the outside fiberglass or just knock the leftover wood off also for tabing in the new transom same thing an in or so past were the tabing is gonna lay or just scuff what's there and degrease and acetone and go over the old thanks for the help pics are coming just haven't had time working on the boat

You just need to grind down to fresh glass and no further ... Wipe it down really good with acetone before reglassing ..

Does yours have the OMC ?

 

[Bigtrout29]

Hey nope it has the merc 165 and the mc1 out drive so I am in the process of sanding off the old butter and left over wood noticed around the key hole is getting thin like almost an 1/8 but also noticed around the vent holes isn't much either am I still ok or should when read do a layer of poly and 1708 before I butter the transom in

This pic is the first time it ran in 5 years of being in a barn points and condenser and boom as u can see the wife was happy

Good you have the merc ... I hear tell the OMC 's are bad news ..
I would think you don't need to add glass to the inside .. You can install the plywood then build your thickness with the glass going on the inside ..
My understanding with I/O the thickness at the key hole is pretty important to get right ...

 

[Bigtrout29]

I pulled out 2 peices of 3/4 inch ply one full sheet covering the hole back and then a peice that was about 8 inch above the key hole and 6 inchs past the first stringer

 

[Bigtrout29]

Hey guys almost ready to put this thing back in does anyone know of a place around Kitchener ontario the sells Polly stuff and fiberglass the place I was gonna get it decided that the next 2 weeks is a good time to go on holidays lol

 

[Bigtrout29]

Ok guys the time has come sorry for the long time posing will be picking up all the stuff I need tomorow hope the rain holds off I am using poly for the rebuild is there an alternative to 1708 as I can't seem to locate it anywhere in my area and in Canada to ship it there is a charge for chemical thanks for the info

 

[sphelps]

Shouldn't be a hazmat fee for the 1708 I would think .. You can do a combination of csm and woven cloth ... Csm down first followed by the woven wet on wet ...
