ProPulse adjustable pitch composite prop??

[fowl intent]

I was wandering thru West Marine this afternoon, and saw a new prop by ProPulse, made in Sweden. The prop is made of composite material, supposedly 40% stronger than aluminum. It has four blades which can be adjusted for pitch in 1 inch increments between 15" -21" by simply loosening 4 bolts. Plus it offers the flexibility of being able to replace individual blades if one is damaged. I have been having some prop problems (see earlier posts), and thought this might be a good way to determine the proper pitch for my boat. Anybody had any exerience with these props, or any other composite props for that matter?

fowl...<br /><br />Just went onto their website... VERY intriguing, and as props go, fairly priced... I might just have to try one out, as I too have been struggling getting my boat propped correctly for the variety of conditons I operate in...<br /><br />Thanks for turning me on to this bit of info...<br /><br />Obiwan...

ob1,<br /><br />How about letting me know what you find out. In the mean time, anyone else heard of these props? How they perform? Thanks all.

Check PowerboatReports.com They did a comparison of the various composite props a while ago. As I recall, the Piranha props came out first, then the ComProp. The ProPulse was farther down on the list.<br /><br />I have been running the Piranha and ComProps. I get slightly better hole shot and speed with the 4-blade ComProp over the Piranha (blades are thinner and have a sharper edge), but the Piranha has replacable/interchangeable (but not adjustable) blades. I am running a 90 HP outboard on a 17.5 ft. skiff.

Re: ProPulse adjustable pitch composite prop??

I was running a ComProp 4 blade for the 2nd year, I launched the boat, started the motor, put it in reverse and all 4 blades broke off at an idle. I have a 1979 140 inline 6 Merc. There wasn't anything in the water and I didn't hit bottom or the dock. I have no idea what happened.<br /><br />Thought I would let you know about my experiance with them.<br /><br />Craig
