Hi folks
I have inherited a 9'6" rib ( glass over ply ) tender in excellent condition powered by excellent '97 honda 5hp 4 stroke. Currently it goes 10 to 11 kph / 5 kts (gps). I have not confirmed the engine rpm as waiting on a tacho. std prop ( tidy condition)
I would like to go faster if able and have read the ideal hieght of the antiventilation plate (AVP) is top just dry at wot. The AVP is in line with the bottom of the keel. At wot the AVP is prob 6 " below the water line.
I'm guessing this measure of AVP dry may be when the boat is on plane, Not sure if I can achieve this unless I find a patch of downhill water.
My question if I was to raise the motor so the AVP is in this ideal position then the top 1/3 to 1/2 of prop will be behind the transom and not in laminar flow water. Do I have to go without this ideal postion due to lack of HP ? or would it be worth my while to lift the motor say 1" and try it ?
Thanks
Regards Don
