I posted this in the Prop section.... probably should have just posted it here.

For you guys with Scarab III's. What props are you running with what power?

Thanks

Andy

with stock 502's I ran.. 21-23 Mirage and Mirage plus, then Hydromotive Q-4's 22 pitch , Q-4's have workrd the best, then with the 525 SC motors I stepped up to 27-28" Q-4's , Now with the 565 cuin N/A motors I still spin the Q-4's 27" @ mid to upper 70's .. 1983 Scarab III w/TRS drives

With stock 454 330's I was running 23 mirage plus'. RPM's were 4600 at WOT, top speed a blazing 50 mph.

Before that I ran regular mirage 21's at 5200 rpm. Ran 59 but had some engine problems so I decided to go up in pitch.

Not sure about your boat, but if it turns out you need a 23 mirage, or 21 mirage plus, I have one of each in the garage that I may sell.
