Thanks again. I suspect that the transom is marine plywood. Most fuel tank placement is below a flush deck , which as you know, the deck is constantly being spray with seawater. Pray that there is an access hatch, not just an inspection plate, to remove tank, should there be a fuel leak. Some boats require the deck to be cut out to access the tank. A common procedure for tank placement was/is to fill cavity that the tank(s) sits in with foam, after installation. It is my understanding that this practice fills voids and minimizes movement of tank should its straps loosen. If the fuel tank and inside transom cannot be accessed for inspection, then this boat, in my opinion, is less desirable. Replacing a transom is usually performed from the inside of a boat. If my friend had to cut out the back-aft cap just to access the transom, this would be a major job. He doesn't want to have to spend another 10 grand on boat repairs. THX!!!
Grady is a couple of steps up the ladder in both construction and build quality from your SeaRay. Its a well designed, thought out boat with none of the deficiencies/ scenarios you bring up.
Transom Rot: Grady glasses and gel coats the transom inside and out. Transom rot isn’t an issue unless the owner drilled holes thru the skin of the transom and didn’t seal them properly. If in doubt, a moisture meter will tell the story.
FYI smearing 5200 in the hole is not sealing properly.
Fuel Tanks: I have two. Main (92) aft, Reserve (52) fore.
Both tanks have full length and width, screw down hatch covers with quick access inspection ports in each cover.
Tanks are cradled and blocked in place. You can have a tank out and laying on the ground in less than an hour using a screw driver and a razor knife
If there is a weak spot I would say the wiring. They use tinned wire and decent components but the routing and bundling is much to be desired, at least in the model years I’ve owned. I’ve upgrade components and pretty much rewired everything over time
Power: I/O power doesn’t translate to outboard power well. Weight distribution, weight to horsepower ratio and the outboards better trim angles all add up to better performance with less horsepower. I’ve always used 75% when evaluating comparable hulls
