| I have a 2004 DF90 Suzuki on 1750 Crestliner Fishhawk. Have always ran stock aluminum propeller 14x19. Hole shot has been very good with this combo. When the prop was brand new, I could reach 40 mph (GPS) at 5600 rpm which is a little above the recommeded operating range for this motor (5000 to 5500 rpm). Motor is mounted on the center hole.
Over the years, I have shaved a little material off of this prop through normal wear and tear. RPM's will run up to 5800, top speed is down to about 38 - 38.5 mph. Hole shot remains very good. I have a newer spare aluminum prop but it tends to suck air / cavitate easily and is more finicky with trim angle.
I am considering a stainless prop this year. Have had recommendations to go to a 14x18 prop in stainless but was hoping to get some info from others who have made a switch on a similar combo. Suzuki's are a little tougher to size up due to unconventional gear ratio of 2.59:1. |
