Hey there folks, at long last I have my boat in the water. Did one heck of a lot of work! This is my first boat and I chipped each piece of paint with pride.... and wore a mask :)

It took me about a month to completely clean the bottom and prep for painting. It had been sitting in the water for about 2 years (or more...). A few small blisters but nothing bad. Sanded with 300, rubbed everything down with denatured alcohol, and put two coats of Pettit Trinidad antifouling paint on.

Gas tank foaming was another story... that was a b**ch. I should have purchased a second quart of marine foam. Learned my lesson there. Ran a line of Funny Pipe from starboard to port for drainage (as with this boat, the drain hole is too high, leading to a lot of standing water. Everything is sealed with silicone to prevent water getting in -- including the access plates. Painted the foam with acrylic paint to prevent water getting in. Tank was fully cleaned before installation.

There was a crack near the starboard console and when I removed the tank cover, the floor was a bit wet underneath as a result (especially over the sump). Using Git Rot and sawdust, I was able to fill the holes formed over time, and sealed it with Marine Tex. It's solid as a rock now.

Had an overheating problem with the engine. I couldn't get over 3000RPM without going in to overheat mode. Found a terrific Yamaha mechanic down here who discovered and cleaned all of the corrosion out of the water jacket, discovered the boat had the wrong spark plugs and too-long throttle cables, got the bow lights working, etc etc.

I have a question for those of you with 90HP Yamahas and 15-16 foot Whalers regarding your prop size. My mechanic thinks that the current prop (it's a stainless 17K) has too big a pitch, and that it should be around 15. I have had someone else tell me a pitch of 19 would be better. Right now I get to about 4000RPM / 27MPH, but I think it should get closer to 5000 RPM per the mechanic.

Any advice on what pitch the prop should have?
