F225 Yam Prop - The Hull Truth

BuddahB · 12-01-2005, 09:23 PM

I currently have a prop marked 15x17 on my 2003 parker 25SE. I easily turn 6000 RPM's with half a tank of gas on calm water and trimmed out. Can't get better than 40 MPH out of the boat. Would putting a Ballistic 14.5x 19 increase the speed, or would it be pretty much the same because I'm losing some diameter while gaining pitch? Your thoughts... Thanks in advance...

Brian,

If you have that prop it will not hurt to give it a try. I am not familar with Ballictic (michigan wheel?). The only thing I can tell you for sure is that if your current prop is a Yamaha I would try the 19p SW series. Or try a Merc Mirage 19. Both props are real similar and style and performance.....size for size.

I think if you are loaded(gear,fuel, people) your current prop isperforming pretty well for a F225 on a 25ft Parker...... which is not a real light weight boat to begin with. 40 mph on a 25ft boat with a single F225.......no bad numbers imho.
