Comprops???

[archer59]

Anyone replace an aluminum 3 blade prop with a 4 blade composite? This would be for 75 Merc.

Thanks,

Nick

I use a comprop when I fish Lac Seul each year, just in case some unmarked rocks "happen to appear" underneath the boat. I run a 115 Johnson and have been satisfied with the comprop. It's a little quicker out of the hole, but I lose a little off of the top end when compared to the factory 3 blade. The comprop doesn't seem to handle the tighter turns at top speeds quite as well as the 3 blade, but overall it works well for what I use it for.

I would use it only in case of emergency, I tired some and don't quite like them, they don't last long.

Beware, if you consider using it on rough bottom lakes, bring another spare prop + wrench, if comprop hits a rock it will shatter blades leaving you without propulsion.
