WallyGator12000 Posted August 7, 2009 Share Posted August 7, 2009 I just bought a 1996 9.9 four stroke mercury for my 14' lund. Problem is, with the extra weight of the four stroke, plus me (I weigh 225) the boat will not plane. I had this problem with the old motor (1985 9.9 evinrude 2 stroke) and it was fixed with a new prop with a 9" pitch. However when I took the prop off of my new merc, after doing a search of the part number 48-828152-7 I realized I now have a 7" pitch for the prop. The 7" prop is in pretty good shape, not new, but no major dings or anything like that.It is my understanding that a lower pitch will increase your ability to plane. Any ideas? With a new prop, can I drop below a 7" pitch, or am I just out of luck and always need to find a boat partner for the front?Thanks for the help!

marine_man Posted August 7, 2009 Share Posted August 7, 2009 Yes, a 7 Pitch Prop would improve your ability to plane over a 9 pitch prop.I would try putting some weight in the front of the boat, and see if that helps. You're probably right on the edge of enough hp for that boat & the load carried that you might have to try weighing the front down to get on plane.marine_man Quote Link to comment Share on other sites More sharing options...
hydro Posted August 7, 2009 Share Posted August 7, 2009 Another thing to try, if you haven't already, is to tilt the motor in toward the transom one notch at a time to see it the trim angle is the culprit. Quote Link to comment Share on other sites More sharing options...
