Re: Mercruiser 5.0 Performance Boost
Although I have never used one, I have heard quite a few negative comments about the shifting props.
Go to your local Merc dealer. He should have a prop program where you can 'buy' a prop and take it out and test it for the weekend. If you're not happy with it, you take it back and get another one, until you find the one you want.
If you're currently running a 21" 3 blade ali, and you're getting into the recommended RPM (4200-4600), then go for a 21" HighFive as a starting point. (select a prop that takes you towards the top end of the max revs, 4600)
You can use Merc's prop selector website.. http://appcenter.mercurymarine.com/propSelector/home.do
