1978 Alberg 30 Propeller

[fkittson]

I want to change my propeller from a two blade to a three blade. The boat has a MD7A 13 HP Volvo motor and the prop need to be replaced. It is still the original one that came with the boat. I'm not looking to gain a lot of speed, but if I'm going to replace it I want to look at all options available.
Does anyone have any experience re prolong a Alberg 30.

I would check your max speed in flat water now, then give the size of your prop and the speed you have now to a prop shop and let them recommend for you. Nothing like empirical data. If you currently attain hull speed, a 3 blade will still help with stopping the boat in reverse etc.

I agree but just wondering what others have used.
