Motor up, but not too high or you overheat your power head. Need at least 10 lbs of water pressure.

And it depends on the boats set up. A few pics would make life a whole lot easier for all involved.
A whole boat shot, a transom shot, etc.

Don't forget, not all props will live at the surface. It's not fun (or cheap) to throw a blade at speed.

General rule for jackplates:
Raise the eng a bit at a time until either water pressure drops or RPMs go up but speed doesn't, whichever comes first.

What I did was got a water pressure guage and temp guage installed, I have baked an engine once...the tempature horn didn't work .......( . )( . ).......:cool: I also have a jackplate guage to let me no when to stop, experiment with the lifting of your jackplate and note the indicater, lift it to the same place all the time .

No disrespect intended Kim, But, the best jackplate position will change, depending on the weight changes in the boat (passengers, coolers and gas load ), ambient temperatures, and water conditions.
