I'm re-powering a 24' pontoon boat with a 90 hp Honda. Have never run a 4 blade prop. The boat will be used for 95% cruising, usually not far off an idle. The 5% will be for pulling the grand kids, under 100lbs, and likely at wide open throttle. Pretty familiar with what to expect there.
I'm also familiar with the process for finding the correct pitch using a 3 blade prop (looking for max rpm on a lightly loaded boat), and assuming no change when going 4 blade (same process).
My question is for those that have run both 3 blade and 4 blade on similar rigs, and all else being equal with properly pitched props, what differences will I notice one vs. the other? Is this going to be something I'll see and feel easily (with my butt dyno), or will I need to study the tach and GPS to see the difference?
IS THE 4 BLADE WORTH THE EXTRA MONEY?
Please, this is not a ski boat or a big block Donzi. It's an old man's pontoon boat! There was a day when I cared about results for those type boats, but that's a day long ago.
Thanks for your thoughts! -Al
