Well McGillicuddy thanks for your reply. I spoke to a tech at armstrong brackets and he said for every foot that your motor is away from the boat you have to go up 1 inch. So you were accurate in what you are saying. My motor is 38 inches away from the boat so I already know I have to go up 1 hole already. I put a straight edge on the keel and leveled the motor with that straight edge and I measured 2 1/4 inches from the straight edge to the cavitation plate. So every hole is 3/4 inches, so if I go up 1 more hole I will be 3 inches above the keel which according to the tech from armstrong is where I want to be. Im afraid if I go 2 holes it may be too much. And yes I was referring to Garys boat and I read what was written on that post. My motor according to the manual should run between 5000 rpms - 5750 rpms, but I would prefer to run closer to that higher number as possible with 3 men on the boat and at least a half a tank of gas.I remember Fr.Frank sying that on one of the other post.I think you are accurate in saying that the windshield and the hardtop will add weight and drag. I also have a full canvas enclosure which is more of a parachute. But Im hoping that raising the motor 1 more hole will increase my rpms and speed. The prop is a Apollo michigan stainless wheel xhs 14 3/8 x 15 . I was reading on that post with Gary about a stern lifting prop, I wonder if that would help me in my situation. Well one thing for sure is I have to raise the engine at least one hole and then take it from there, because as it is right now I have water shooting up from the motor in a vee fashion at cruising speed.My problem now is I have to wait until the spring because its a little cold here in N.Y. right now and the boat is on land. I dont know if this is the right prop for the boat but I would definitely appreciate some feedback. Thanks guys.
