I am a new boat owner, I have a 1995 24ft PlayCraft Pontoon, and it has a 120 HP Outboard motor with an Aluminum Prop on it that is in pretty bad shape. It cruises at about 30-35 mph whan the darn thing will start and I have posted that question in another forum on this site. I know nothing about choosing a prop to get a little more performance out of the boat, Any help with this would be greatly appreciated!
