Vector Handling


       Recently sold my 454jet boat and now have an 81 Vector with 175 Johnson is this boat a handful or what? The boat has a hot foot,dual steering,hydro. jack plate with 4" set back,18 gal. fuel tank in stern with battery and the prop is a13.5x23 pp. mich. shooter.

        I have read the other Q&A but still feel the need to ask the following. Bounces at 45 or so and I can not trim it out, I have to slow down. Boat runs fine and handles well up to that speed then hang on! Bouncing bow must be the porpoising everyone is talking about but this chinewalk I do not follow? My boat also is hopping all over the place when I turn.

         Any suggestions would be super, I would like to start with the handling and move up with stable speed, and please let me know what speed and rpm's I should see with changes.  

Thanks Steve


You need to trim it out to get through the porpoise zone. Trim out at 35 mph and then throttle up. The chine walk will come at 55 and up. You need to get through one to get to the other.
