With it in the first hole it is about level with the bottom of the boat.If you go to the second hole it will start bouncing at full throttle.I might have a tack at the shop .What should it be turning.Whatever it's turning it is plenty fast now.When I try the 25 on it it will probably be to much...
I just did the water test with the motor raised 2 inches.Its running like a scalded dog now.I also tweaked the high speed jet on the carb that helped some also.Now it's scary fast
Thanks everyone
Here are pictures .I raised it 2 1/8 inches. Now with the pin in the first hole the front of the cavitation plate is slightly lower than the bottom of the hull.When adjusted all the way back it is slightly higher.Im going to try the second hole first..mI just redid the transom.
The boat transom is 16 inches.on the motor bottom of the mounting bracket to the top of the cavitation plate is 18.I also measured a 72 25hp johnson a 15 hp johnson and a9.5 hp johnson all appear to be 18 inches.I also measured a 30 hp johnson and it's 22.So I assume it is a short shaft
