just bought a fixer upper and need some help...

[petrey10]

i just bought this boat from a friend and it needs some work. i was wondering where you guys would start. the owner said that there was some type of foam beneath the floor that got wet some howand makes the boat some what heavy. I don't know hardly anything about boats and stuff some I was wondering if someone could point me in the right direction. I know that it has a 140hp onboard mercurycruiser that is a carburated 4cyclinder. and the side of the boat says Larsons or something of that sort. i wil have to post pictures later.
