[QUOTE=zt260]The last set of gears looked like yours, but that was because I felt it coming apart and idled in. All the others were completely trashed. Not much left in terms of teeth.

The small tank is 112 octane for runs over 10Ibs of boost. I can switch fuels on the fly in seconds

Bmax's lower case will bolt to any bravo upper, but Dean uses his own vertical and prop shaft that are not interchangeable with bravos. Dean told me the new lower will bolt up to my existing Bmax upper.

Thanks for the info, I always assumed the shafts were the same but now I know there is actually a difference. When I have trashed lower gears I have felt it thru the floor of the boat and headed straight in. It always spreads metal thru the whole drive too which sucks ,Smitty

I've never run WOT with full boost. But at 12Ibs I see 105mph
I plan to push it over 110mph this summer if everythingís perfect.

Smitty,

The real beauty of the Bmax is the separation of the upper and lower. The oil is not circulated so a blown lower will not affect the uppers oil.

Hey ZT, I used to have a 253 with 710hp and kept blowing drives.(5 in 2 years). The term "running out of boat" does apply.

That would be nice but I bet dean also beefed up the vertical shaft with bigger dia too,Smitty
To use a Bmax lower you have to use a different vert shaft.The BMax shaft is thicker like the prop shaft. the coupler is larger also.

I bet when he get the new lower gears .and he puts his bravo vert shaft[to fit your] he would guaranty it to the 950 hp/TQ

Dave the prop looks real close to the cav plate on the foot?

Also how do you like the BMax crescent lower ? I am trying to get Dean to give me a price for 2 the last 3 weeks.

I have the standard low water pickup merc XRlower case. I wonder if the B Max crescent lower will pick me up any at around 100mph?

That picture is with my standard length lower, the maximus clears by 1/4". On my 2" shorty which I run now, I had to grind the plate out to clear, but it works great and I gained a few mph.

I really like the Bmax crescent lower. Its tube is shorter and the skag is smaller. Itís defiantly faster than my old sportmaster lower. I don't know how it will compare to a stock merc lower. I was always afraid of blow out. I highly doubt you will lose speed, and there's a good chance youíll gain, especially if you start raising the X dimension, and try different props.

I realize I'm pushing it, but you would not believe how stable it rides at 100mph. If nothing else I like to cruise at 80mph, so the extra power comes in handy.

I would have brought a larger hull, but I trailer this boat and anything longer would be too much trouble with the family. Honestly I'm happy where I am right now, and I don't need more HP.
