All those with late 80's Formulas. I'd be very interested to hear what props you're running with power, etc. Especially 292s and 311s. Thanks.

I'm running Hydromotive QV-4's 24P on my 89' 272. I like them b/c they give good stern lift but also decent bow lift compared to the 3 blade mirages. Mid-range cruising is great with these 4 blades. Three other 87-90 Formula owners (272, 292,311) are also running QV-4's on my lake.

I am going to try a set of Bravo 1's when I find a loaner set.

I think it would be a toss between the Bravo 1's and the Hydromotive QV-4's.

Looking for some 26s to try since HP peaked @5600 on the dyno.

Thanks all. I'm running Bravo 1s [26p] and they're great except they're blowing out on the holeshot. I guess I'll get used to nurturing her up to plane. 1989 292 SR-1 with 1998 502 EFIs.
