Re: Recommended prop for my 91 johnson 40hp on a 17' Grumman aluminum bass boat?
If it has a prop check the size under the prop nut do a test run and get us the max rpm and speed.
If you read the stickies at trhe top of the page you'll understand better about prop selerction.
Even with all the info prop selection is still a bit of a crap shoot.I think you can see from your info it would be a total not very accurate guess.All that said I would guess a 13 or 15" pitch. But I sure wouldn't run out and buy one
based on my guess.
