Location: Rhinelander, Wisconsin | It's all dependent on load, propping, and horsepower. A 5 blade will plane a boat in WAY less time and distance than a 4 blade, which will plane a boat in less time than a three blade of the same pitch and diameter. Different blade shape, cup, and configuration will provide lift to the rear, center, pad, etc., and offer differing performance characteristics. I found the fastest prop for the 1890 configuration and load I was running was a Revolution 4, not the Tempest Plus I expected.
Load the boat rear heavy; longer time to plane. 'Pushing less water' (which means the boat isn't planed out) has as much to do with the trim position at increasing RPM, pitch and diameter of the prop, and engine height as anything else. I had an 1890 rigged with a 200 Opti that was about 4 seconds to plane and ran about 56 MPH. I also had an 1890 rigged with a 200 Opti that was about 6 seconds to plane and ran quite a bit faster. Only difference was the prop and one hole engine height.
Short answer, an 1890 one hole up rigged with a 200 Opti spinning a Hi 5 prop will plane nearly instantly and pull an entire herd of kids.
Hope this helps! |
