We have a 2003 F225 with 17" pitch 3 blade s/s prop. It is a (edit) 17-M. Yamaha prop. Boat is a Double Eagle 206ext. We have run this prop for 6 years and it is OK. I would like to try a 19-M prop or something similar. I have some numbers for you guys and hope to get some suggestions and thoughts on a good prop for this boat.
In Up to a 1.5 foot sea swell with 2 people on board the boat weighed about 4300lbs which is about as light as we run it.
1st speed test with 17-M prop
3500Rpm - 23.5mph
4000rpm - 28.5mph
4500rpm - 32.5mph
2nd speed test with 17-M prop
RPM MPH
3000 13.3
3500 23.5
4000 27.5
4500 30.8
5000 35
5500 38.3
6000 42.7
6100. 44
We bought a 4 blade aluminum prop 19” pitch and tried it out for a couple of hours at a lake years ago but performance was worse, so hoping to do better this time.
I feel like if I got the same prop with higher pitch, performance should be predictable - a bit faster and similar low planing speed?
We have trim tabs.
What do you fellas think?
Following some advice Here I will see if I can track down a used prop on the buy/sell forum? Then sell the aluminum prop and keep the 17-M for backup.
Thanks
