I worked with tohatsu on the height of the mount. no difference. I measured it and it ended up only being about 1 and 1/4 inch lower than stock.
Got back with tohatsu yesterday and they are stumped. They think the boat is two big for the engine and that is why the rpms are running 1200 rpm under nominal . Nominal being according to them 5500 rpm. They are sending me free of charge a 6 pitch prop to test and see what that does. They agree that I am not getting 6hp at the prop if im not getting 5500 rpm but I can tell they want to say it is because the boat is to big/heavy.
