Prop and Jack plate continued.....

[Cane Pole]

I checked the jack plate position/setting. I leveled the boat, then trimmed the enigine to level the cavitation plate. With the boat level, and the motor level, I placed a carpenters square under the boat hull and checked square to jack plate.

The bottom of hull (not lowest chine of hull) is even with cavitation plate. I don't have a water pressure gage, but I had a extra pair of eves with me, so I raised the plate 1 inch. Did not push it any further. No change in rpm.

I will order a water pressure gauge before I continue. I drug my boat home form the lake, so I can check things easier with you all uns help. And I do appreciate all the help.

CP...give me all your information and I'll post on bass boat central. Todd should know where you are supposed to be. It will be a prop to pad measurment.

I will need to know the current propshaft to pad measurment so he has a baseline though.

I will try to get the measurements maybe by tomorrow. It raining here.

1. center prop to ground = 14 3/4 inch

2. bottom of hull (lowest point of V18 hull, not center chine) = 21 inches

1. center prop to ground = 14 3/4 inch

2. bottom of hull (lowest point of V18 hull, not center chine) = 21 inches

cavitation plate is 1 inch higher than the bottom of hull.

4900 rpm @38 mph (gps)

"1. center prop to ground = 14 3/4 inch"

Now there's your problem, you would probably get better than 4900 RPM's and 38 MPH if you wus running it on the water instead of on the ground!:rolleyes:
