Q. I have an older Glastron I/O drive fiber glass. The boat is 1986, it has a 4 cyl OMC engine. I think it is a 2.6. It takes on water when pulling skiers. I am not sure, but I don't think it leaks very bad when just riding without skier. When it sits in water over night it doesn't leak. I checked the seam where top and bottom are joined and applied some silicone, but it didn't stop it. I have been thinking about putting a light inside the motor cowling on a dark night and see if I can find anything. Any suggestions will be greatly appreciated. Thanks!

A. It's possible that there may be some miniscule cracks or other failure between the hull and the transon. There may be enough structural tension to remain sealed when the boat is in a static state.
The extra stress that the skier places on the transom may be relieving that stress and allowing water to leak in.
The best way to check for that is to make sure the bilges are completely dry, and have someone inspect the transom joint while you're pulling a skier. Since it's back by the engine, make sure they take extreme care to avoid moving parts and hot surfaces.
