How do I know what propeller to buy for my boat?
When choosing a propeller, choose a pitch that will keep the engine RPM in its recommended operating range. Going under the range will cause the boat to lug, while going over can cause engine strain. Blades have other important features built into their design. Rake is the angle between the blade and the hub.
What prop do I need for my bass boat?
Most bass boats run a 25 or 26 pitch prop. Some that carry really heavy loads or extremely large boats might run a 24. Some faster boats run a 27.
What is the best propeller for speed?
Enertia 14 1/2″ x 18. The 18-inch-pitch Enertia propeller delivered the best top speed and the worst hole shot. It’s expected that more pitch will equate to higher speed, since pitch is the nominal distance the propeller moves through the water for each revolution.
What prop pitch is faster?
The lower the prop pitch, the better your hole-shot. However, this comes at a price: top speed. The lower pitch makes the engine reach maximum rpm at slower speeds. Conversely, a higher pitch will deliver greater top speeds, but slower acceleration.
What kind of propeller does a Mercury 115 outboard use?
This well-worn Lund 1700 Fisherman was our test platform. The Mercury 115 outboard is a motor that runs well with an aluminum or stainless steel propeller. Last summer, in part one of “The Right Propeller” I offered some guidance to Boats.com readers with step-by-step instructions on how to evaluate prop performance.
Which is the best propeller boat to buy?
Four options (from left) Mercury Vengeance, Black Max, Trophy Plus and Lazer II. The yellow paint indicates that these props from Merc engineering have been perfectly trued. The first step was choosing four props. To do that, we used the Prop Selector mini-site that’s part of the Mercury Marine website.
How big of a prop do you need for an outboard boat?
The recommended prop size was an 18- or 19-inch pitch. With that, we went out on the water. Mr. Blatz had topped off the 27-gallon fuel tank, and our load also included three people with a combined weight of 420 pounds. We motored to smooth water, where there was no wind and very little current.
What’s the RPM of a black Max propeller?
It might have been interesting to try a 20-pitch Vengeance, but with that prop we’d be running on the very low side of the motor’s 5800-6400 rpm range. Underway, the Vengeance seemed to produce a little less bow lift than the other stainless props, and you could feel it slipping in turns, though not as badly as the Black Max.
