I'm finding out all the details on my recently purchased Di Marco, what I'd really like to know is if the prop/gear combo sounds reasonable for this engine/hull. The engine is 440 inch BBC with probably 525-550HP (DD2000 guess), reverse manual turbo 400 trans, 18% over gears and 11 1/4" x 15 prop (2 blade SS). I have not had a chance to run it yet, next weekend will be first time out, just gathering input and ideas right now.
The previous owner ran a ton of down-pedal and was honest with me that the boat porpoises bad without the pedal, I have noticed the rear plates are slightly up from level without up/down pedal applied (I read level is correct), the other thing I've read is prop placement (for and aft) will have a dramatic effect on porpoising and such, is my thinking close to right?
If the plates are set too high, that would definately be a good indication of why there is so much downpedal needed.
