Hey guys, just tried out my new acme prop on my 92' supra sunsport. I went from a 14dia, 14 pitch to a 13dia, 11.5 pitch and the rpms jumped from about 3K when weighted at approx 23mph to nearly 4K with the same weight and speed. The boat planes much better now (the 351 PCM would barely plane with the old prop) but I'm worried this may be a little high in the rpm range. Any opinions?? Acme does have a 12 pitch also, would this be better suited? Thanks
