The best prop is a guessing game....<br />The first item you want is to find a prop that puts you at the top of the recommended RPM range for your engine, with a normal load....<br />From that point, depending on the performance values you want, it can be fine-tuned from there.<br />As for the trim system, I can't answer that...we pull the parts off the shelf according to the book.

Your trim cylinders are a direct interchange....<br />As long as you use Pairs....<br />The older rams with the 2 short trim lines are a 1" bore.....<br />The newer rams with the different length lines are 1 1/4" bore......<br />Either will do the job..... as long as they're used in pairs.....<br /><br />What Walleyehead said about the Prop Choices.......
