I took out my Margay for the first time today. It is a prize boat that I put a 150xr6 on. My top speed today was 32mph So something is wrong. It was real hard to get on plane. I hope/believe that maybe my jackplate is just set too high. I leveled my pad in the garage. I then leveled my cav plate on my motor. Then measured from my pad to the floor and the center of my prop to the floor and got 3.6″Is this a good for engine height? Help appreciated!Thanks,Tom
