I have used Comprops on several boats. The perfromance is usually equal to or better than aluminum. The baldes break off if you hit something hard, saving you motor. Even if you want the performance of SS, Comprops are good for spares. They are light, cheap, and won't ding you boat as readily as Aluminum or SS. West Marine, Cabelas, Bass Pro, and Boat/US all carry them.

Are Comprops, those made of a compsition plastic or resin? I had only see one before when I was on a ship in Guam and the Steward hit some coral and busted the blades to nubins. The Chief Mate (fisherman out of Cape May when he was not sailing) was not too happy and told me that he did not like those kinds of props. It has been awhile since then and I really can't remember what he said the down side to those were. I will take a better look at them.

Check out this site http://www.piranhapropellers.com/ . Ship Shape TV http:www.shipshapetv.com did a show on propellers a little while back and one segment was on Piranha props. They did some impressive demos, running a boat over a large piece of timber, shearing all of the blades. They just pulled the prop, replaced the blades, and did it again.

Comprops are composites. Ditto for Piranhas. Piranhas have replaceable blades. As far as the blades breaking upon hitting the coral, that is what is supposed to happen. The blades break absorbing the impact of the strike instead of the lower unit or power head. On Piranhas you you just replace the blades, on Comprops you replace the whole prop. Usually the broken blades are enought to get you back in.
One other advantage, electrolysis (sp) is not a problem with Comprops, as they contain no metal. Piranhas have an aluminum hub. Proper maintenance should eliminate this problem however.
Comprops are really pretty inexpensive. I checked BassPro and Cabelas, the Mercury versions run $53 to $83. Even if you prefer stainless props these props are perfect for spares. They do have some weight and horsepower limits on them. Check for more info:
Note to B Bear you Honda 90 will accept the same props as Mercury 90s

Thank you all for the advice and help. The comp props sound like a good choice for exploring on the rivers.
