any experience with adjustable props?

[unixgeek13]

Hi all...<br /><br />I have a 20' Regal Cuddy Cabin. I want to experiment with different prop pitches to find the best setup. I see these ProPulse props that are pitch adjustable and you can even replace fins as needed! Too good to be true? Anybody tried this prop? Performance?<br /><br /><br /> http://www.westmarine.com/webapp/wc...001&langId=-1&catalogId=10001&productId=47168 <br /><br />Thanks all!

What would happen if you didn't have EXACTLY the same angle on all blades?

good question. I wonder if that's possible. I didn't buy this thing yet... I was hoping for some feedback first. They might be strung together such that they move in unison, but I really don't know.

I haven't heard of Pro Pulse before. I'm probably going to purchase a Piranha prop next spring (http://www.piranha.com/). There are a lot of reviews for the Piranha and they've certainly been around for awhile.<br /><br />I'm sold on it from the perspective of the blades breaking off when a hard object is struck and replacing it with a spare $20 blade on board.<br /><br />--Hise

That actually looks pretty slick and not a bad price either. <br /><br />Replaceable blades too. <br /><br />I'd buy one if they had one that went past 21 pitch.

I checked out that Pirahna, looks very similar to the ProPulse, except that the ProPulse lets you adjust the pitch just as easily as it lets you swap a prop blade.<br /><br />This boat is new to me, and it gets up nice with a 17" pitch, but maybe that's not all there is.. I'd love to find the optimal pitch for my setup before I invest in a nice stainless.<br /><br />Thanks, as always, for the thoughtful replies...<br /><br />...Steve...<br /><br />--------------<br />'89 Regal Sering 195 w/ Mercruiser 135 HP I/O<br />'02 Sweetwater 170 Pontoon w/ 75 HP Mercury O/B<br /><br />"...and loving it!"

I've just put a Propulse prop on my boat and it seems to work well. Better acelleration and good grip when i turn hard.I lost 2-3 knots in topspeed because the prop is 4-bladed, i guess its higher resist in the water.Adjusting the pitch is very easy, just 4 bolts and when you turn one blade the others will turn too.The wheight is much lower than alu. and steel props, that will save the gearhouse.If you damage one blade its very easy to change it.Its a good idea to have same spareblades whit you.(Theres a lots of stone in my lake.)<br />Richard

I have been using Pirahna now for a year. Saved my bacon twice already. Replaceable blade for $15 and change. Not variable, but for the price you can't go wrong.
