P/N 767683 G2 TBX hub kit
I run a 620FS with a 4 blade 24P RX4. This prop hold the weight of my heavier hull even at lower speeds. Top End perfomance was not hurt. I'm able to get mid sixties with a fully loaded boat.
Good information EdStachowski! I'll try the 15x22 soon after it arrives. Depending on RPM's, I may order a 15x24 to try. Any idea what RPM's you're running ?
Here are the performance numbers:
3 Blade 14-7/8x22
As you can see, I didn't lose anything with the 4 blade. More RPM and a hair in speed. I do feel I had faster bow lift and it maintained lift. I did bump 60 mph with the wind to my back. The noticeable difference was turning sharp and accelerating in turns...NO SLIP whatsoever! That 4 blade definitely has a different sound.
Note: I did also have the vent ports opened full during testing.
I'm anxious to try any further recommendations!! 24 or 26??
You can try a 24 but the revs may be lower than the recommended 5400
BluewaterBill, I've been thinking about your statement regarding RPM's with the RX4 24P. Do you feel I'm getting it all with the RX4 22P based on the information provided?
I have a 2015 Ranger 620FS that came with the 250HO G2 and a RX4 x 22P. It was in the middle of June and I could only get 5400 RPMs out of the motor, which seemed low. The dealer let me try a Rebel 3 blade x 21 P and it was terrrible, blew out easy and seemed very loose. Put back on the RX4 and it was like having 4 wheel drive. Better grip, could trim it all the way up without any blow out, and significantly more stable handling. Ended up with a RX4 20P and got my R's up to 5800 however the only thing I noticed was my GPH went up.
