When picking your Mercury propellers, be sure you talk to your services guide to the proposed WOT here and RPM range in your engine. will not fret if this seems bewildering, Wholesale Marine presents a simple-to-use Mercury prop selector Resource this means you’ll know particularly which Mercury Marine propellers you’ll require.

superior-thrust propellers are made to supply greatest electric power at lower speeds, generating them perfect for weighty loads and towing.

Turning issue Propellers utilize a squeeze casting approach to produce thinner blades. The manufacturer offers stainless overall performance at aluminum rates.

Four-blade propellers are noted for their easy Procedure and enhanced Manage, Primarily at lessen speeds.

Cavitation: normally confused with air flow, cavitation outcomes from h2o vaporizing or “boiling” due to the acute deficiency of pressure around the again in the propeller blade. quite a few propellers partially cavitate through ordinary Procedure, but abnormal cavitation may well result in “cavitation burn up,” metallic erosion or pitting with the prop’s blade surface.

4-blade styles do the job effectively with boats which can be difficult to get on airplane, underpowered or used in watersports where prime-conclusion pace isn't crucial.

Aluminum propellers are lighter plus more affordable, making them popular for relaxed boaters. They can be much easier to repair but Never offer you the exact same degree of performance as chrome steel propellers, Primarily at greater speeds.

Engine rpms and pitch are inversely relevant. rising the pitch will decrease engine rpms and decreasing the pitch will maximize engine rpms. to be a common rule, a two-inch boost in pitch will end in a reduction of 300 to 400 rpm.

you've got a non thru-hub exhaust if there won't be any exhaust holes about the engine gearcase throughout the prop shaft. Prop Splines

These propellers have bigger blades or a bigger diameter, permitting them to drive much more h2o and produce more thrust at reduced RPMs.
