Re: Poor planing performance?
Well....my boat (see signature) has the same 14x23" prop. My boat is similar to yours. Also, boattest.com used the same prop as I am using when it tested my rig. My performance is fantastic. Sunday we had two adults, 4 kids and a full tank of gas tubing. Tubing with a two person tube that weighs about 50-60 pounds. My boat definitely planed longer but it planed in 6-8 seconds. When not tubing it planes very quickly.
Here is a thought, on my old boat which was a 4 cylinder, it was having trouble planing. Mechanic found out that a cylinder was not firing and did a tune up. It solved the problem. I know your a mechanic but maybe double check to see if all cylinders are firing especially after you changed plugs. New plugs on a 2009 though??
