I recently aquired a 14 foot Lund aluminum boat with a 25 HP big foot. It runs well but will only do 10 MPH, traded the prop but it didnt help much. Is this motor capable of higher speeds. It runs great but super slow....
Should be doing twice that and then some. First thing to check is your RPMs. See if your revs are near where they should be at WOT. Let us know what you find.
