You very likely desire a reduced pitch in the event you’re shifting major loads often. in the event you’re just cruising all-around, lower pitch 3 blade props are great. in order to up the ante a tad and go water skiing, Then you can certainly stick with very low pitch and take a look at four blades.
0-twenty MPH: 3.ninety five seconds discover To buyer the knowledge and facts contained During this general performance Bulletin is approximate and subject to many different factors and variables. it can be supplied being a guideline only and shouldn't be relied upon as agent of precise effectiveness. Your boat’s functionality may very well be distinct than the data contained During this efficiency Bulletin owing to varied aspects, which include your boat’s true fat, wind and drinking water circumstances, temperature, humidity, elevation, bottom paint, boat choices impacting wind/h2o drag and/or boat pounds, and operator skill. you should ensure the specs and overall performance knowledge with your certain boat/engine blend together with your seller prior to acquire.

Rake - The blade angle in relation into the propeller barrel/Heart. This is certainly expressed in levels. High rake propellers are preferred for top engine mounts. Low rake propellers cause less engine pressure.
The intense rake presents wonderful speed and boat efficiency. The intense cupping suggests you’re not sacrificing RPMs. on the very same time, you may have much more Manage.
the most significant concern you'll need to remember is sizing. numerous boat entrepreneurs have messed up and purchased the incorrect dimensions prop. Don’t really feel as well negative if it transpires to you. The quantities can search perplexing. Just be sure you Examine and double Check out before buying.
