I’m still in my prop research phase for my 6.8 RC BF 225 Honda. I’m seeing fairly contradictory reports on 4 blade props. Have any experience? Tell us about it. Thanks.
Had a solas stainless 4 blade untill someone stole it. Much better at giving more low speed grip and holding rpm in rough conditions. Seem to remember having to drop 4 pitch sizes in comparison to a 3 blade aluminium prop. Solas are extremely helpful and experts in getting you the right prop for your needs first time around.
Yup I have a Solas HR4 on BP. I had twin CR outboards on the last boat with Mercury Rev4 props on. I’ve tried a lot of props in my time & the Rev4 is the best I’ve had. The grip is phenomenal in the rough, they can run higher than a normal 3blader, the boat just feels much more confident & “planted” in the water. The downside is loss of economy by around 5-7% & a marginal reduction in top speed, but this can be mitigated by raising the engine a hole. It’s very much trial & error when it comes to setting up prop/engine/hull combos.

Same here as the other guys, more grip, quicker onto the plane, no blowout on tight turns, l went from Suzuki 3 x 143/4 x 23 to Suzuki 4 x 143/4 x 21 both stainless. Humber ocean pro 7mt, Suzuki 175. 40knots @ 6100rpm
Thanks guys, this really helps. I’ve seen claims of great grip and hole shot in the advertisements but hearing from real life users is what we alll want.
I’m leaning towards a Turning Point 4 blade because they have an exchange program so that you can really dial in the right pitch. That takes the risk away from a wrong guess. Stay tuned.....
4 blazers are a great compromise. I always seem to end up propping with a rev4 now. Went from a 3 blade 27” raker to a 25” rev4. Fixed cavitation problems and grip when accelerating and lost no top end. My engine is very high, Prop shaft is level with bottom of hull and it even works like that.
I have a powertech LFS 4x16x20 on DF225 2016. Compare to a Suzuki 3x16x20 I have the same rpm more slip in the same rpm's. With LFS we have better boat control in rough waters with more consumption pel mile.

4 blade props will lift your boat on plain quicker but you will lose top speed
good if your loads are very heavy depends what you want it to do ?
I just got in from my first—brrr cold!—sea trial with my new-to-me 2008 Ribcraft 6.8 with Honda 225.
6100 rpm, 51 mph. Prop 4-14.5x17 ss Turning Point prop. I was incredibly pleased, especially that the engine ran so well. He speed/rpm target seemed very good for a lightly loaded boat: 2 up, 40 gallons fuel.
