[QUOTE="Toolbagtyler, post: 486488, member: 26358"] I have a 1992 Johnson 9.9 that I installed a 15 hp carb on. It’s on a 92 Tracker guide v16 with a small front deck. Gained about 4-5 mph on average with different weights in the boat. Currently have a 9 pitch prop on and got 14mph at 5650 rpm with two guys, two 29 group batteries, two trolling motors, 6gal tank and gear. Got 17 mph at 6500 ish rpm alone. If I put an 8 pitch prop on do you think I would gain more speed when loaded? Would I over rev alone? I feel like I’m right on the edge of plane by myself but just can’t quite get there. [/QUOTE]
