" Hi,

2001 Johnson 25 HP


" Hi,

2001 Johnson 25 HP is being used as a kicker on a 21 ft boat; it's main purpose is auxillary power, although it will be used for trolling. It's setup w/ remote controls and steering, but It's mounted off center and doesn't plane the boat. Currently at full throttle with the stock 13 pitch prop it's getting 3800 RPM; the operating range is 4500 - 5500, there is a 7 and a 9 pitch available. Which prop do you think would be better? Thanks for any/all responses,

Jon "
