97 four winns qx transom replacement

[bking507]

Hello,
I looking to possibly start a transom replacement on a 97 qx standa has anyone done one of these? Can it be done from the inside. I just purchased the boat and this would be the first project I would be taking along with engine coupler, drive shaft yoke, u joint, and gimble baring

Yes, I/O engine outdrive (right?) You will be taking out the engine, etc . and then it can (should) be fixed from the inside.

yes, 3.0 Volvo Penta. the motor is already out. it went right to the shop to have coupler and stuff done. they are now telling me probable reason that it went out was because transom is rotted. it was already 2k for repairs but now their talking another 2500-5000 to replace. this is why I may considering to take on the project myself over the winter. if I store the motor inside will I need to winterize the boat should I change all the fluids as well or just leave it one the pallet and worry about it come spring should never get under 70 degrees where I would be storing it

Ayuh,..... Welcome Aboard,..... Atleast drain the water out of everything,.....

Even though it shouldn't get below 70*,.....

I'm looking in to different fiberglass and resins what are some of the better options as far as ease of use, workability, sealing.
What have others used to repair a transom

I used polyester resin, same as what was used in the boat’s original construction. (Except I did a better job than they did. )

I used the 435 and it worked great. A little cheaper too... just fwiw.

 

[kcassells]

I only use US and it's the thin EEppooxxyy. A lot of us here use them.

 

[JASinIL2006]

I used 435 from US Composites, too. It's their standard polyester resin for layup in marine applications.

I ended up having someone do it for me. getting it done for 1200-1800 depending on all rot that is found Has to cut away back section and rebuild from the outside in. hopefully after all the work is done we can at least get it out to test it out

One of those shops doing it backwards. It works. But imo isn't right. They are cutting away the outside skin. It's faster but not as good

thats backwards

and if you did the work yourself you would have spent $2k or more for the materials, not including your labor

so besides doing this job backwards (going from outside inward) what is the shop skipping in its efforts? my guess the fact that the stringers are rotten and the flotation foam is soaked and they will simply leave that rotten and soaked.
