I have a 1988 Bayliner Trophy with a OMC 4.3L V6. Right now I have 2 props for it a 17 and a 19 pich. Operating Rpm for the boat I believe is 4600-4800 rpm. The the props I have the rpm full throttle is 5100 for the 17 and 4900 for the 19. Top speed for both props is between 25-28 MPH. This boat is set up for fishing with downriggers and stuff so it has a good weight load on it. Are these props still to low maybe, what should top speed be.
