Hello all

Well since I my neighbor bailed on me I wasnt able to completly pull the boat cap. So I did the next best thing at least in my mind. Got my floor jack and placed it under splash well and lifted it as much as I could and then I was in demo mode I feel like I got quite a bit done in about two hours. Ive posted some pics of my work. I posted a pick of the boat logo Fish n Ski to see if any one else on iboats has one made by this boat maker and to offer any advice on how they are in the water especially since this thing has never seen the water since Ive had it.

Pics of demolished rotten transoms on this forum are like blood in the water for sharks! We love em!

I like your work-around with the jack.

I may be wrong, but I think "Fish N Ski" is a type of boat rather than a brand.

Re: transom repair help

Preciate the comments Wood. Well I got a some more work done this morining in fact I got most of it out. Can anyone suggest how I can get the last of that wood out of very bottom of transom without damaging it? Also should I leave that fiberglass border in as a guide for new transom or cut it out and make it a little thicker say about half inch taking it to 2 inches thick or would that make boat too heavy. Let me know what yall think? See the pic I've attached. So what grit grinding wheel do I need to take the remaining wood off?

Re: transom repair help

Use a 4 1/2" grinder with a backup pad and 36 grit sanding discs. Take All of the wood out. Go ahead and knock out your drain tube. You will need to replace it with a new one. The Entire outer fiberglass skin of the transom needs to be clean and flat. Top to bottom corner to corner.

Re: transom repair help

Im assuming thats a rubber backing pad. So would you suggest me making transom thicker then?

Re: transom repair help

I just got done with my transom replacement on my 1972 GT160. I used a gas powered chainsaw to get the last little bit out of the channel behind the stringers. Don't worry too much about cutting the bottom of your hull if it is in good shape you will have to apply a good amount of pressure with the saw to hurt it. I would keep it at 1.5" just make sure you use quality wood or marine grade. I used a sheet of oak because it naturally resists rot. I completely fiberglassed the wood before I put it in so it was copletely waterproof. It's not that bad of a job just alot of dirty, sticky, ITCHY! work

Re: transom repair help

Yep, rubber backing pad. 34 grit discs. Keep the transom @ 1 1/2" just like it was. No need to change anything. I'd recommend you use underlayment plywood or Ext. Grade FIR plywood. 3/4" and Lam it together. Nate1220's suggestion for OAK is NOT correct unless he is talking about SOLID WHITE OAK. Oak Plywood is NOT laminated with waterproof glue, will NOT resist rot and is NOT recommended for use in the construction of boats.

Re: transom repair help

I've had good luck using a 36grit one like this on an angle grinder. You do have to use a bit lighter touch with it as it doesn't flex like a rubber pad.

Re: transom repair help

Yep, you can use the flapper discs too! Just a bit more pricey and I think they wear out a little faster.

Re: transom repair help

Hello all,

Im back with some question or problem depending on how you look at it. First, in the process removing drain tube I damaged or better yet broke part of back section, how do I fix. Also, in the process I poked a few small hole in bottom of hull should I repair from inside, outside or both? Final question when you say laminate the plywood together(for new transom) do you mean fiberglass them or something different? Thanks in advance.

Re: transom repair help

Post some pics of the damage and the holes. Doesn't sound like it's gunna be much of a problem.
Heres a drawing of how I recommend building a transom using ext. grade 3/4" plywood and Polyester resin. Coat both pieces with resin and REALLY soak the edges. When dry cut a piece of csm about 2" larger than the transom. Coat the two mating sides of the transom pieces with resin and lay the mat. Use a 1/4" nap 6" roller to dab and roll the mat onto one piece of the transom and then lay the other piece on top of it. Clamp it up and let it dry. Hint: Drive small nails in the corners to hold in place, remove the clamps. Lay some plastic on the garage floor, set the transom on the plastic and place some heavy items on top of the transom to weight it down. Really spreads out the clamping pressure. 3-4 concrete blocks work great

This thread will give you some ideas too
