stevo 0 Report post Posted April 19, 2012 Helllo to all Monterey owners. I have a 1994 26' cruiser. My props are currently C21, we get about a top speed of 25mph, and I am wondering if anyone has any input regarding going with a different pitch/prop? Thanks.

Since there are so many considerations it is hard to say the C21 is the right one for you and your boat. Fortunately there are several web based programs to guide you to which is best for you and your boat but the one I found most helpful was: www.mercurymarine.com/propellers/prop-selector/ What I liked about this web site is they ask several questions about your boat (size, weight, engine) and what you desire (speed, performance, fuel economy). Then they will recommend a prop for your specific boat and needs. I think there are only four steps and it takes less than 2 minutes as long as you have the information.

Rip5 0 Report post Posted April 23, 2012 What is C21? 21 pitch? We will need to know. 1.) What engine/drive do you have in your boat 2.) What is the engine horespower 3.) What is the drive ratio of your sterndrive 4.) What are your RPM at WOT ? 5.) What is the manfucturer's recommended RPM at WOT ? 6.) Is your boat bottom painted, clean from growth? That is a good start for now..... Share this post Link to post Share on other sites
