Anyone have a 189trx with a 150FS? What kind of speeds do you get. I run right around 50mph and think I might need a different prop. I have a Tempest Plus P21. I don’t know a whole lot about all the setup. I raised the motor on my jack plate to a point where I got a couple more mph, but if I go up any more my rpms go up but no increase in speed. Any dvi e is appreciated. Thanks
