"I think that my engine is working pretty well - do you think that a change in prop would make that much difference to the speed? It hits about 5000 rpm at full throttle." The rule of thumb I heard regarding engine RPM/prop pitch is that for every inch in pitch, up or down, you can look fo...

I have had it up to 37 mph. However, I would not recommend that speed to anybody with this type of boat. Safety becomes an issue quickly as the boat wants to either start lofting or bury the bow. With the 90, and a 14" pitch prop, the boat is very stable at 28 mph and the motor is loafing. No s...

Thank you sir! That was quick.

oops. The image won't display. I must have done something wrong. Any help out there?

http://gallery.bateau2.com/albums/userpics/10651/normal_P1010507.JPG Don't want to but I have to! I am moving overseas, and cannot take it with me. BRAND NEW 90 HP 2 Stroke Yamaha w/controls and tach. Less than 5 hours on motor. Smart tabs. Compass. VHF. 12volt outlet on console. This rig is ready ...

I've got the problems w/the motor resolved. New ignitions coils and kits in the carbs worked wonders. Now I need a new prop. Gonna try an aluminum w/a 15" pitch this wkend and see how that works. Have a 22" pitch stainless on it now. Uploaded a few more pics. Low resolution from a phone ca...

I've got a 22' Aquasport I'm trying to sell. Pics are available if anybody is interested.

Check the Building Method http://boatplans-online.com/proddetail.php?prod=GF14. It explains when to check for symetry. I don't have plans for the GF16, but I'm sure the building notes have the info in there somewhere in more detail.
Good luck.

I think I'll run a PVC under the center of the console back to the motor well and out the transom. I'd like the pickup to be as low as possible to get cooler water. I don't mind a little water in the cockpit from drainage, but I don't like things on the sole that I'll either trip over or stub my toe...

When I built my V10, I used wooden dowel pieces on the inside of each stitch. I had to start at the transom and work my way forward. The bow was especially difficult and the first piece of ply actually broke before the bend was complete (cheap exterior ply). I think the plans actually suggest that y...
