Re: Comprop Props - are they any good?
What are you putting it on?
I had one on my boat (18" w/ 175hp I/O) and it threw all four blades in a hard turn, under power. I am well under both the weight and HP limits set by the manufacturer, but still the blades just let go. With that said, their customer service was outstanding. I had a replacement in 9 days, including shipping both directions.
On the other hand, my father has one on his pontoon boat, with a merc 75 on it. It has been absolutely trouble free for 7-8 seasons.
For only a little bit more money I would suggest a Hustler/Legacy prop. It is hands down the best aluminum prop on the market.
