I have seen a lot of #4 and #6 and #6a's some # 3's . The #4's have a 750 hp limit. more than that is borrowed time. Depending on the ratio, t-man and hp ect is the life. On some of the prodjects 1100 plus "real hp" 1 year upper gearsets are micro pitting. The ratio makes a big difference 1.62 weak-1.24 net forged better. The torque is multiplied by the ratio therefor more torque, slow speed big prop faster failure. break-in is important.

The best point of a #6 on a pleasure boat is the reliability factor...knowing I can go out and have fun and the one thing that will probably not break is the #6....we can lose water, fuel pumps, alternators, all sorts of small BS stuff, but that #6 is very dependable. It is not fun and relaxing to take your boat out with a pair of 800 sc's mated to a bravo cause you know that at any second, that drive can let go...just the way it is. Some guys get away with it..for a while, but eventually, the odds catch up with you. I am guessing you can pick up a new 6 with the transom assembly for around 35 to 40 K????? It is a lot to stomach...I guess it is worth it, just depends on each boater and what their priorities and budget allows. A 500 EFI with a bravo XR works just as well when it comes to comfort and reliability!!!!!!

Catman,
Dude, what are you smokin? There have been times when we have passed the big red Scarab, and we're only a single!
Forget about comparing it to a 6 drive, I don't see any way the weismann drive could out perform the Bravo drive for performance or dependability. In fact, Nigel has had two weisman drive failures this season alone. And that's with less than 530hp in front of them! With the exception of the Utz fountain taking out a log in Cleveland, I don't believe there have been any other Bravo drive failures in Super V lite single or twin.
I really wish Nigel would just go back to Bravo I drives. It was faster, more reliable and he deserves to be in a competitive boat again.

Simple question between large drives....

What percentage of drives failed while racing this year by style. Limit to the Supercat, SuperVee and SuperVee Light for a more even distribution of results.

Merc #6 Weissmann

# of Races ?? ??
# of Failures ?? ??

% of Failure ?? ??
(fairure rate)

I have been out of the loop this year so maybe someone can come up with the numbers. This should give a fair comparison between brands. The HP on all of these run between 530-750 but are driven hard. Probably should add a correction factor for the lower HP SVL's to be more accurate, but just a straight distribution should give some indication.

Default Hiya kent!

Good point. I'd like to see these numbers myself. But, I would like to add one point. While the SVL teams are running less than 530 horse, they also are running Bravo drives rather than the number 6 drives. So, maybe we need to look at the numbers for


.....................# of units racing # of races # of failures

Weisman--

Mercury #6--

Bravo (all)--

The problems that occured with nigel had nothing to do with hp.
It is a situation that is occuring on the same side. It is a part that we do not manufacture. Since then we have switched brands.
As for nigel being competetive it is a weight issue. When the weight comes off he will be there.
The part that I am interested in is how much does it cost to rebuild bravo and how often? What is the cost when the gimbal snaps and you loose the whole drive and prop and sink your boat?

Cool

I give Pat credit where credit is do. It's takes a big man to try to run against Mercury. But it is just too bad that his drive will end up where all the Kaama stuff is. RUN BLACK! and run out front!
