I have a 2004 Yamaha OX66 200hp outboard that I bought on a boat earlier this year. Compression is excellent and I have put about 40 hours on it so far this summer. Last two times I took it out, I noticed water draining from the wiring harness area. when I tilt the motor all the way up to trailer. I opened the cowl today after about an hour of run time and the bottom is wet. It is not clear where it is coming from. I ran the motor with the cowl off and didn't see any leaks anywhere and when I hooked the hose to the motor flush didn't see any water leaking anywhere then either. I will try and track down a barrel to run it in (my water pressure at my house sucks). The motor runs great and no overheat alarm is going off. I should mention it sounds like the popet valve is tapping and plan on replacing that. Any ideas?
