Hi folks. I'm new to this forum so please forgive any apparent ignorance. From what I've seen looking through some of the threads/posts, this is the place to be for intelligent answers to my questions.

I've got a '95 Glastron family runabout I/O. I just finished putting in a new floor due to rot around the drivers seat pedastal. I had to pull all the seats and side panels, tear up the carpet and floor, then I laid new ply, glassed it and recarpeted. Re-installed the seats and launched for the first time this season.

After a few minutes I noticed water in the bilge. Checked the engine for leaks, etc. found none. I had my local boat mechanic check things out. He couldn't find any apparent leaks while in the water, so he pulled it out, let it dry and filled the bilge with water. It appears that the transom had been previously repaired around the garboard drain plug (which I had never really noticed before). There are stress cracks in the gelcoat at the top (far above water line), which I've never worred about. It seems the leaks are primarily around the drain plug and the cut-out where the engine connects with the out-drive.

Obviously I'm not happy with the news, especially since our boating season out here in Colorado is just getting under way and my family's chompin' at the bit to get on the water. I just want to make sure we stay on it, not in it....

Any suggestions for making it through the 5 month season as is? The mechanic is going to try and tighten any bolts he can get at from inside, but not sure how many he can reach with the engine in the way. I've also thought about trying to silicone around the outside of the outdrive, but not sure if it's worth it.

If I can make it through the season, I'll pull the engine next winter and rebuild the transom the right way. I just would like to get some boating in this year, but above all, make sure my family is safe taking the boat out.

Open to any suggestions.

Re: Glastron I/O transom leak

If it's leaking enough to notice, it's probably rotten inside.

Rather than a quick fix, I suggest you just bite the bullet and get 'er done. Starting out to do things the right way will save time spent trying temporary fixes.

An alternative would be to just run it as-is, and try to stay near shore. If you're not in imminent danger of sinking from the amount of water that's coming in you can still use the boat, just be aware of the risk....

Hi!
The easiest way to make clear your transom is not rotten is to drill some holes at the bottom of the transom. Be sure not to bore through your transom.
I do not think that your transom is like humus.

when you drill the holes (from the inside) look for rot in the shavings.....

drilling holes will give you a core sample.....

ask your boat mechanic if the transom will last the season......he will know.

you might want to replace the drain plug with a bigger one.....that will take the wet wood away from the area.....but bear in mind.....adhesives dont like to stick to anything wet.

The problem is,...... When the transom gets that Rotten,+ starts Leaking,.....

The Outdrive is no longer aligned with the Motor,.....
You'll be Lucky to get 10, 20hrs. out of it before the Coupler Strips Out.....

Good Luck....
