I cant figure out why the heck my boat wont get up to speed. I found out that I was running on one cylinder a few days ago, so I changed the head and spark plugs to fix. Then I addressed the issue of my cavitation plate being too low by raising the motor 3 inches. Progressively the boat is getting faster but it is still really slow. At WOT I can hit about 15 mph by myself and MAYBE 10 mph with a passenger. The boat is so ridiculously weight sensitive.<br /><br />I will decarb the motor tomorrow and pull the prop off to check if it is spun. From the looks of the prop, when it is still attached, it looks fine.<br /><br />What could I possibly be missing? Any insight is appreciated, as I would like to overtake canoes sometime this month.<br /><br />Thanks,<br />Sal
