Crestliner Fiberglass Transom Plate?

[WinnipegBoatMan]

Hi Guys,
I have a 1979 AMC crestliner Cursader, Fiberglass hull.. Its rated HP is 100HP, and last year rebuilt an inline 6 115HP mariner(Merc). Now my issue is when I did the repower, and drilled the new holes, the plywood core seemed wet as i Drilled it.. and now i'm concerned that I have a rotten Transom on my hands?? There are no cracks in the fiberglass of the transom, but now I'm concerned that if I don't reinforce the transom with an aluminum or Stainless plate, the whole transom will fail on me.
So my question is, should I reinforce? and if i DO, what should i use? and where?
Thanks Guys!

Re: Crestliner Fiberglass Transom Plate?

You probably have more problems than a rotting transom. When a fiberglass boat has a rotten transom you can just about bet the stringers below deck are rotten too.

Overpowering a rotting fiberglass boat with more HP than it's rated for is a recipe for disaster.

You need need to fix your boat the correct way or sell it and buy another. I doubt anyone on this forum will condone a plate fix or an overpower job on your boat.

You have project on your hands.

Your transom needs re-building and there is probably more associated rot below deck.

If you add a metal plate ........it will be one more item to add weight to the boat if it sinks........ it will not serve any safe purpose.

Heed the advice above.....you're 15% over the rated horsepower and a rotten transom to boot, is for sure problems ahead. The 15% over with a solid hull and transom wouldn't cause any issue's (although not recommended).

You need to repair it properly, before gunning it down the lake....safety first, always...
