RE: Engine and positioning ?
Nice work! [8D]
It looks like its gonna turn out to be pretty light. I'm gonna suggest using a .46 on your boat. If you use a 3 1/2 to 5 lbs per 1 hp ratio, you'll get good performance and response from your machine.
Keep up the good work and keep us posted on your progress~ [8D][8D][8D]
