So I still come on here and enjoy reading all the info and giving input to other fellow Rinker owners although I sold mine about a year and a half ago. You guys really have a great forum and superior to alot of other ones. Alot more activity also.
I now own a 2004 Chapparal 330 Signature with twin 350 mag mpi horizons and twin B3 drives. Love my Rinker but really love this boat. The configuration is the only one of its kind. Take a look at some photos when you get a chance.
Anyways when I bought it I had trouble planing and seemed to just cavitate until it got up on plane and then was ok but seemed like it was lugging the motors only reaching about 4200 rpms. I did a lot of research and contacted the previous owner as well as Chapparal and had motors scanned and discovered the boat was intended to come with 24 pitch props not the 26 props that were on there and this mistake was made from day 1 by the dealer that sold the boat and never realized.
Long story short I did the math and determined indeed the boat needed atleast 24 pitch props to get rpms up and help with holeshot. So I went to the best, Hill Marine and discussed with them and purchased a set of Hill Marine Signature 4 Blade 24 pitch props. Ill let you read on for the results. You can read the hole thread or just skip to the end of the Summary. Worth reading. Like a new boat. Thought I would share it with you guys for anyone considering swapping props on a cruiser.
