AFE CUMMINS 6.7 Posted January 30, 2016 Report Share Posted January 30, 2016 I picked up a new prop for the signature boat. It's a Yamaha Saltwater Series 2 14.75x23. It managed to push the boat up to 65.1 mph at 5500 rpms. Stats on the HS4 15x22 prop were 59 mph at 5900 rpms. Here is the Garmin Helm screenshot.

linesider 159 Posted January 30, 2016 Report Share Posted January 30, 2016 If they make that prop in a 21 you may want to give that a try. I don't know about the f300, but the sho I have makes power all the way to 6k. At 5500 wot I was missing out on speed. Holeshot improves with the smaller prop as well! Great numbers you posted Link to comment Share on other sites More sharing options...
AFE CUMMINS 6.7 Posted January 30, 2016 Author Report Share Posted January 30, 2016 I had a 21 pitch that ran 63.2 at 6000 rpms and the dealer told me that I needed to get my RPM's down. I think the F300 is recommended to run a few hundred rpms lower than the SHO. Link to comment Share on other sites More sharing options...
SCFD rtrd. Posted January 31, 2016 Report Share Posted January 31, 2016 Nice numbers, glad you got her dialed in. Guess I'll have to be happy with 61 mph with the 250 SHO. Link to comment Share on other sites More sharing options...
AFE CUMMINS 6.7 Posted January 31, 2016 Author Report Share Posted January 31, 2016 What prop are you running now? That SHO motor is probably faster than the F300 as it has less drag in the water and more torque with the short shaft. Link to comment Share on other sites More sharing options...

ChrisB Posted February 2, 2016 Report Share Posted February 2, 2016 It is BBlades version of the Bravo FS in 24 pitch. Could only get up to 64 today wind was bad Link to comment Share on other sites More sharing options...
SCFD rtrd. Posted February 3, 2016 Report Share Posted February 3, 2016 Man, that's hauling azz!!! Where did you have the jack-plate set? Link to comment Share on other sites More sharing options...
ChrisB Posted February 4, 2016 Report Share Posted February 4, 2016 Jackplate is set at 3. The prop stays hooked up at higher settings but puts me into the rev limiter to early. Link to comment Share on other sites More sharing options...
SCFD rtrd. Posted February 4, 2016 Report Share Posted February 4, 2016 Jackplate is set at 3. The prop stays hooked up at higher settings but puts me into the rev limiter to early. I'm confused about the "rev limiter" statement. Are you saying this is the best prop or do you need to test more props. How does this prop hold in the surf/chop and in turns. I looked at their web-site, but can't find the difference in Standard and Lab Finish, other than the price. Looks like the price jumps from $750 to $1,200. What exactly is a Lab finish?

AFE CUMMINS 6.7 Posted February 5, 2016 Author Report Share Posted February 5, 2016 That's incredible to be turning a 24 pitch prop up to 59K-nearly 60K Rpms! I heard Mercury props were good, but this company has taken it to the next level with the lab work. What diameter are you running and do you have the vents plugged or unplugged?

ChrisB Posted February 5, 2016 Report Share Posted February 5, 2016 Prop has very good grip in chop and in turns. 3 is where this prop needs to be for speed. Probably could turn more pitch at higher settings but if you get the prop to high you lose the leverage to carry the bow and end up losing speed. I would like to try a 25 to see if I am at this point but not bad enough to spend $ 750 on another prop. Lab finish is basically a blueprinted and balanced prop with thinned blades and sharp leading edges. They are fast but get dinged up easily. the Bravo FS and the OBF are the compromise between stock and lab finish props Link to comment Share on other sites More sharing options...
