    Default 25 HP Mercury need new prop?

    When I go in forward the motor will go fine at lower speeds. When I increase speed the motor whines and doesn't increase speed. From what I have read it appears I need a new prop? If so can I change this while it sits in my pontoon? First time boat owner. Sorry for my ignorance

    You can mark the prop,take a short spin and if the line don't line = spun prop. Yes you can change it on the pontoon just be careful not to drop anything in the water

    Where is the best place to order one online if it is bad? About $100?

    Draw a line across the hub diameter with a sharpie or something that will leave a mark on the prop and you can get a prop from Andrew who runs this site
