picking the right prop should result in your engine running inside the developed rpm assortment at Wide Open Throttle (WOT). Your owner’s handbook should incorporate this spec—generally 5000–5500rpm for an outboard or 4200-5000rpm for the sterndrive—or your mechanic or vendor may well know.
Elevation: lots of small, trailered boats are used at vastly diverse elevations, including substantial mountain lakes and bays at sea amount. minimized concentrations of oxygen at superior altitude induce engines to produce significantly less electricity (about twenty % a lot less at 7000').

destroyed hubs are quickly person replaced and this lowers the “alternative Price tag” in the prop strike. Also, In the event the prop is bent although the hub is intact, replacing just the prop is usually less expensive. Either way you stand to avoid wasting $$$ When you have a challenge.
The next thing to consider is diameter. this will likely also determine the propeller’s RPM abilities. Over-all engine overall performance may be improved by picking out the ideal check here boat prop. the amount of blades is also a thing to consider.
3 or four blades perform very well in possibly sterndrive or outboard applications. a few-blade patterns give you all-all-around functionality with a benefit on prime stop velocity.
Apollo XHS Series of outboard propellers Merge the power and longevity of remarkably polished stainless steel with CAD developed blade geometry to make a quality superior-general performance propeller that’s the best benefit about the water.
Engine rpms and pitch are inversely similar. growing the pitch will lessen engine rpms and decreasing the pitch will improve engine rpms. as being a typical rule, a two-inch boost in pitch will result in a reduction of 300 to four hundred rpm.
When figuring out which Yamaha outboard propellers to obtain, you need to be considering its pitch and diameter along with the quantity of blades. The diameter is definitely an imaginary line circle within the propeller blades. The pitch of the propeller is how far in one rotation the boat moves forward.
