400 ss prop selection? whats everybody running? 4x3 3x3 xr props, non mercury props? i have 500 efi boat with 28p 3x3 props. runs at 4800-4900 maybe and i get 52-53 mph. my good friend has same boat with bravo 3 xr 4x3 27p and gets 4900 same speed 52-53 mph. i know its not a go fast and its hard on them I'm just trying to figure out which props to go with. talked to mr cig with same boat and he has 3x3 26p get 55 mph at 5100. whats everyones thoughts

Just use what formula recommends for that year. Its not a go fast.

Ya I know it's not a go fast. But when it was built the bravo 3 xr props were not out. Just wanted to see what everyone else is running

Based on what Mr. Cig gets with 3x3 26's, I'd test a set of 4x3 XR 25's. I have one perfect set you could use for a test. Just have to find yourself another set (Bblades?). BTW, the XR props were designed for boats like yours. Heavy and a lot of HP.

I have a 2005 370 SS with 496 HO's that has Bravo 3X drives. Pretty sure it has the original props, 3x3 26p running 5200 - 5300rpm at 56-57mph. I've thought about going to a 4X3 set for better mid-range cruise.

25p 4x3 xr's, thats what i was about to buy. makes sense if my buddies boat with 27 p at 4800-4900 runs same speed but his does plane easier and cruiser a tad better.

I have a perfect set in the swap shop. Just sayin'...

im trying buy these props off of you you won't reply back........lol

I may have two sets of 25 pitch XR props for sale. I'll check and post back. They have a few dings, but I'll price accordingly. You can try them, then send to BBlades to repair and tune to your application. I was running them on a 38 Fountain with 496 mag ho's. I destroyed an upper Bravo 3X drive and the other upper was right behind. I went with a bravo 1X with five blade maximus props. I like them better and the maximus has somewhat of a rubber hub that the 3X drives do not. I understand the solid hub bravo 3 props are very hard on the upper gears and XR upper gears don't last much longer than the X upper gears. Boat is a little harder to dock though, I will say that. I plan on adding a bow thruster to help.
