Question on a stainless prop...

[CRFan1]

Well, I was thinking about getting a SS prop and using my aluminum one as a spare (keeping it in the boat) but I have a question regarding pitch. The prop I have on my boat now is pretty much dead on and pulls 6K on the tach with 2 people in the boat (60 efi 4 stroke Merc) and about 5800 with 3. For the life of me I can't recall the pitch but I want to say it's a 10.5 by 13 or something close. If i buy a stainless prop do I want to get one that has the same pitch or should I move it up a notch size wise? What performance changes will I get? Whats a good prop (brand) for this motor?

Thanks for the help....

I should also add that my max speed is around 31 with 2 people and 29.5 to 30 with 3. I would say the aluminum prop is pretty close to spot on.....

You should drop to a 10.5x11 that should maintain you rpm. Plus your trolling speed will drop a touch and your max speed will go up a small bit. Biggest advantage is extra toughness and your the boat will handle much better taking off and plane at lower speeds. SS slips less so if you go up in pitch you will lose speed and performance.

An aspect of stainless steel props that many folks forget or never learn is that they are VERY srong and when you hit something solid they may not break. But that means that your crankshaft MIGHT bend a teensy-weensy bit.

Your choice.

True, but in twenty plus years of running I have never hit anything by accident. That includes trips to Mille Lacs, Pelican, LOW around Monument, and plenty of river running and other skinny water. My only accidents are because I didn't slow down and raise my motor. SS benefits outweigh the one maybe drawback for me. Basically watch the lake maps, depth finder and use your head and u shouldnt have any problems.
