I have a ZX225 with 225HPDI and I only see around 68mph and my RPM's never get very far over 5,000 with my TPX prop. Can those who have their ZX225 setup perfectly show me how high your jackplate is set? (Mine is currently raised about a 1/2 inch) I'm replacing my poppet valve this weekend and will be able to adjust the jackplate easily.
