311 w/ 454 Mag Best Prop Suggestions
Hello... I’m new to the forum and have had a 311 for a couple years now. I was curious what is the best prop for the Formula 311. To maximize speed, handling, etc. I had read some stuff that the hydromotove 4 blades were a good fit. But since finding that and doing more searching I can’t recall all those details now. So what’s the best prop for the boat and why? |
I had a set of hydromotive 4 blade terminators on my 302sr1. I forget if they were 22 or 24 pitch. Boat jumped on plane good midrange and top end.
|
thank you.... so you recall if the top speed stayed same or slowed or increased? What prop did you have prior to, the 23 p 3 blade? |
Top end stayed the same. Previous was 23 pitch mirage plus. Boat had 330s top speed 63
|
Thank you... |
I had a 1990 311 with 454 Mags and really liked Lab 3 blade Mercury props
|
I like the way the 3 blade mirage 23p I have on it work.
I was was curious if anyone used the 4 blades and it it resulted in more speed. |
I have had two 311s and found that with 4 blades they would want to bow steer a little. I was turning them out. With the Lab 3 blades 25s I could pull the same RPMs as 23s but picked up 3 to 4 MPH cruise.
|
So you ran 25 p on the 311. What rpm did you spin? I have 23 p and run about 4600 at 62mph. I have 454 mags w/ bravo. I would have thought the 25 would load the motor too much. |
Went from 23 Mirages to 26 Bravos on my 302 with warmed up 420s and TRS drives. Lost about 400 RPMs and 2 mph at the top, but the midrange jumped significantly, and overall the whole boat feels more responsive. It's a trade off I'll take for real world boating.
