I have a Advantage sr 21. Last year i dropped in a new 509 (B and D marine in El monte did an amazing job!) around 600hp range. It currently has a 1.5 bravo 1 stock drive with a 4 blade 24p prop. The boat runs awesome! all around great performance. Hits 83mph at 5800 -6000 rpm, pulls a skiier, cruises around 3200 rpm and turns on a dime compared to my old 3 blade 23p prop.
My question is if it is worth adding a 2" shorty lower unit to a V-hull? will i get increased top end being able to increase the pitch on my prop? will i loose the ability to pull a skier and all around lake use? The sr21 had bad prop walk (chime walk) with the prior 454 and i added dana 1000 planes to correct that when i replaced the engine. Will i again have to worry about prop walk by changing my x dimension?
Thanks for the input.
