Re: props for 336 Formula
I was surprised to hear the Bravo props were giving you too much bow steer. First time I've heard of that. If that's the case forget the Hydromotives, they'll only increase that issue.
Hydromotives, as said, are stern lifting props and have worked very well on the older Formulas in most cases. On my 89' 311 they were a tremendous difference over the 3 blade Mirage 23's that came on my boat, I swapped to 24" Hydromotives. Got 7 mph more at cruise and 3 mph more at WOT (gps).
Question regarding your bow steer with the Bravo props and I don't mean to be wierd here. I would assume you are trimming your drives our as far as possible. Just a thought......good luck.

Out of the hole was a breze with no cavitation and I should be able to spin the props to 5000rpm with more trim and less fuel on the boat.
I had tried the 24 bravo 1 and 23 hydromotive before these props. Bravo 1 had great hole shot and cruise but was short on the top end. Hydro 23 could only spin to around 4500 rpm or so. I will post results with 22 hydromotives when I get back out on the water.
My boat has the 454 mag's so with 502' s the 23p hydromotives might be the right prop for you.

I have to give "props" to Formula Outlaw as he is right on with the hydromotive Q-IV on older Formula boats.

Re: props for 336 Formula
RonS - I have not done a direct comparison by running both sets of props the same day but here is my "seat of the paints comparison". Definitely better on plane with just a little tab needed and NO cavitation. Cruise at 50 mph is 200-300 rpm lower with the 4 blades. With full tank of gas the max rpm is about the same, maybe a little higher with the 4 blades, and top end also about the same speed. Boat definitely seems to run flatter with the 4 blade props. I need to play with trim settings to max performance and ride comfort.
All of that was with a FULL tank of gas. Overall I am very happy with the switch from 23 mirage plus to 22 Hydromotive Q-IV props.

Is this prop the "HYDROMOTIVE INTIMIDATOR Q IV 15 1/2" X 22" " and "HYDROMOTIVE HC-CL22L SS LH"
Anyone test this on the 292 88 non mag? Thinking about trading my bravo 22p for the Hydro's (what sise??), getting only 58mph (4500 rpm) out of them, pre-mirages (Quicksilvers) getting 63 (4800 rpm) but chine walking a bit at WOT. Maybe should have bblades lab the bravos 1's? Both holeshots with both props are great. Are Mirage plus better than the PRE Mirages?
