Welcome to the forum.

3 Blades vs. 4 Blades

"In general the 3 blade propeller offer more speed while the 4 blade offers better thrust and acceleration. Today with the engines producing even more torque, we are starting to see more of the 5 blade products. In general the higher number of blades on a propeller, the lower speed the boat will be able to stay on plane."

Welcome to the forum owensound . We are glad you are here and believe that you will find answers to a lot of your questions. We also provide some humor, of course at no charge to you other than the initiation fee you paid to join this forum ;)

A few pointers for you to do (if you have not already done so) to help us help you:

1. By clicking on your name in the upper right corner to bring up your options select my profile to add into your signature your location (geographic area).

2. Also under your signature add the type of boat you have and its mechanical systems, such as boat type, engine, drives, etc. This way you don't have to type it into to every post you put up. This will help us help you a lot! Without it, you may not get any answers.

3. Use the Search feature in the top right corner of the forum. There is a lot of good information on this forum that will answer many of your questions. We have a lot of experts here with a large amount of life experience.

4. Take a minute to review our Terms of Service, again right corner. There is good information in there that you will want to know including that we cannot discuss pricing. But read some of our other posts on here to learn the work around for that. ;)

5. We like pictures a lot! So when you get a chance, post some pics of your ride. Read through this thread to learn more about how to do so.

6. Take some time to look through the Help (upper right corner) and > Info Center) located under Chaparral Boats Forum on the main page. From there you will find parts guides, brochures, manuals, specifications, canvas installation manuals, vinyl care information, square gauge setup, weather links, computer desktop backgrounds, etc. Lots of good stuff there for you and your Chaparral!

7. Come back early and often to post. We are a community of friendly and some of us are border-line psychotic. But we admit to it and that's the first step to recovery ;)

Again, welcome to the asylum/forum and we look forward to more from you. Don't be a stranger.

I'm w owensound on this. I was lucky enough to find a dealer that let me tested several different props, 3/4/5 blades. I have a 233 sunesta w/ 350 carbed. 4 blade revolution was too heavy and agressive, 3 blades got just a little more top end and finally settled on a 19P 5 blade Hi Five and love it. Bullet hole shot and only lost about 2 mph top end.

I would be more concerned about your rpm's. I learned on this forum different rake/pitch props have different effects on engine rpm. You want to be in the upper limit of your engine's recommended rpm range w/ light load on board (2 boaters & normal gear). 5 blade may work good though.
