My motor had been running at only 5k rpm's, and due to lack of time I took it to the dealer. Mechanic spent a lot of time on it, and talking to Yammi, and I spent $235! I got it back and it runs about 5,600 rpm's WOT with 3/4 fuel & 2 people.
The prop is a 25 TXP, and the hydraulic jackplate is set where it previously ran 70 under same circumstances, and 71 - 72 by myself. (I don't know the height exactly, but it is about 3/4" under pad.)
The mechanic said it's within Yammi specs @ 5600 rpms & 66 mph. 66.2 was the best I could get on a pretty calm day, by myself with a slight chop and 75* water.
The holeshot also seems to be lacking from before all this.
Any thoughts on what I can check? I'm not used to working on an outboard, so I'm clueless on what or how.![]()
