"Does anyone know what the proper prop size for a sylvan bowrider 17ft. 165 mercrusier i/o alfa 1 outdrive would be.I'm running a 14/19 pitch on it right now but would like to increase my speed alittle but drop my rpm's alittle as well.I just feel the rpm's are running high} it at 4,000rpms and I'm not going nowhere. Also whats the difference between 3 or 4 blades.I've been seeing 4 blades as the next best thing.}
Thanks"
