  • Top end speed

    What should the top end speed be for a 1989 Prostar with a 351w and 1:1 transmission?

  • #2
    44 or 45 mph assuming all is good and the boat isn't full of people.

        Well, I need to put the 13x13 prop back on. I rebuilt the carb, replaced the distributor rotor and cap along with new points, and new spark plugs. I timed it to 10 degrees and set the dwell at around 30. I dont think I can do much else besides add GT40 heads

          What prop are you running now, and what speed are you getting to?

            It is a 13x12.5 and I get about 39-40mph

              I'm sure not a prop expert, but that sounds like about the right speed with that prop. Is the speed issue new, or are you just getting in to footing?

                Yeah, I am trying to get into barefooting. And I am not sure what the norm is as far as top end speed goes or things that can be done to get the top end to 47-48 mph. I would like to have some throttle left when skiing at around 42mph

                  47 or 48 mph is a stretch with a stock 351.

                      Been awful dry for you guys for a while. Unless you are trying to pull a real big guy footing, the 351 with a 13x13 should get the job done. There are enough footers on here that someone will jump in with their set-up. Newer CNC props have a lot to offer over the older props when it comes to footin'.

                      How about posting some pics of the boat?

                          How much do you weigh? 42 would be fast for most people.
                          That's about what we run me at. In all fairness there's not a lot of throttle left over at that point.

                            You should get 45 MPH with a standard 3 blade 13 x 13 at 4400 RPMs.
                            With the speed you are getting, sounds like your secondaries are not opening.
                            They should open at 3200 RPMs.

                              When you have your flame arrestor off to check the secondaries, give it a good cleaning. Spray thoroughly from the inside-out with carburetor cleaner (away from all painted objects and loved ones). Air dry thoroughly before reinstalling. The motor needs to breathe.

                              To me, this forum is about love of inboard boats. It is about the sharing of information and, on a good day, some humor. It is not about post count, brand of boat, or any other superfluous labels that lend themselves to a false sense of superiority. Please, respect one another, try to pass on accurate information, and keep your eye on the ball.
