Thread: 25hp pontoon, which propeller?

What are you running now, are you happy with it, what rpm you getting from existing prop? Remember 4 blade going to bite more water and probably drop rpm a little.

When you get a chance look at the prop and see what size it is. That way may give a better idea what to recommend. Props are hard to figure if you don’t know given rpm with a given size, that leads to a bunch of trial and error which can get expensive.

If you can find a prop shop they may have several you can try. I did that and it saved me $200 by not buying wrong prop

No this boat was only used in a cooling pond for a small power plant and was maybe 500' square. It was never propped to run on a lake.

In that case if your having to buy a prop period I’d go with the 4 blade. Your not going to get much speed with that setup to start with and that prop going to give you more overall power.
