I had posted about my motor height a few weeks back. Finally got around to building a jackplate to get my motor up to the correct height. It is a 2013 4 stroke 9.9ml on a Lowe 1467wt. Boat weights roughly 750lbs fully loaded with 2 people. I think i can bring the motor up 1 more inch judging by my test run yesterday. I had installed a hardline tach and went to the lake. At wide open throttle I'm running 7-7.8 mph and only turning 4100rpms. My prop is a 8.9x8.5 pitch prop. According to mercury prop selector it is telling me to drop down to a 6.5 pitch prop but I still feel like the motor will not get up to the 5-6k spec. Has anyone else had this issue with these motors? I feel like my boat is comparable weight to some of the fully decked and built boats I've seen with 9.9 four strokes that run 15-18mph with 2 people. Thanks guys
