ken of long island - prop
Ken:I had the dealer install the 3-blade feathering Max-Prop on my H410 so it was the factory pitch setting - I selected the model that allows the pitch to be adjusted in the water too and have never had to readjust it after the initial installation. I usually motor at 2800-2900 rpms which is the most fuel effective speed (3/4 gallon/hour). This moves the boat under normal conditions at 6.5-7.5 knots (you'll get a knot or more above that in a good downwind surfing condition). With the standard factory prop, you would have to increase your rpms to 3200 or more to get the same speed, and it would also increase your fuel consumption to over 1 gallon/hour.Not only does the Max-Prop maximize the engine output, it allows you to stop on a dime, turn the H410 on its radius and and have a very manageable reverse. Worth EVERY penny! If you keep your boat in salt water, you will also want to get the prop shaft zincs to help maintain your investment.Every so often I get to drive an H410 with a factory prop and can't wait to use mine after those outings.Fair winds,/c, s/v Twilight H410
