better splash well ideas

[Capt Chuck]

my question (finally) is - could i build this out of teak 1x's joined using a biscuit joiner and marine glue? or would i have tgo go with something synthetic like starboard? id like to use wood, but if im going to redo it i want it to last also.

I don't exactly know the config of your 18's splashwell but prior to my transom enclose, I used 1 3/4" teak glued & joined with biscuits for my rocket launcher. It lasted many years. Because of the larger splaswell as a base I could stand on it without issues. I also had the engine tilt cutout.

IMO, I would stay clear of starbord type of materials used to span a large area because of weight and warping. Even the small starboard access door shown in the picture started to bend over time
