Hey guys,
I just purchased a new to me 2010 Nitro Z-8 powered by a 225 Mercury Optimax. Boat has a 10 inch slidemaster jack plate. Prop to pad is 3.5 inches currently. I am running a 25p tempest plus. Boat gets on plane really good, and handles good at moderate speeds. Top end that I have been able to get with an empty boat, 1/4 tank of gas and two people is 66.5. Now that I have her loaded with gear, 4 agm size 31 batteries, and two people I am looking at 63.5 as my fastest and thats at 5400 RPM. I know raising the motor will help increase speed, but how high do you think I need to go? What should the minimum PSI be on this motor? How much will raising the motor affect my hole shot? Does anyone else have a similar set up and if so, What kind of speed are you getting? Thanks a bunch !
