    I have a 18 ft starcraft with a new 115 optimax I’m running a stainless steel 13.25 X 19. Have to trim up to plane out fully do I reprop or invest trim tabs or jack plate. I’m running at Max rpms as soon as I hit trim button and plane out 48 mph gps I’m open for suggestions

    I’d go with trim tabs first. thye can have a huge impact.

    Then i’d put on the jack plate.

    Either of these things can be done with reasonable cost, probably less than a new prop.

    If you need the new prop, i’d look in ebay first…

    Are you having porposing problems? If not theres no need for trim tabs. I would get a bigger pitched prop and also that is more aggressive then your current one.

    speeds just about right! I have a bud with a 189 nitro thats the same speed he runs! Maybe try a 4 blade!
