I thought Dirk's question about driver error was interesting, because I have considered it.
In my case 2 brand new Bravo 3X legs failed, each after about 150 engine hours.
Both failed legs were fitted by Dave Crawford.
In that elapsed time (13 months), the boat, I say, has been driven very carefully. It has not been raced. It has not been revved over 3800rpm. Cruising revs normally being 3500/3600. The boat has not been deliberately jumped although, in rough seas it is true to say the stern has come out of the water occasionally. However, at those moments the revs and forward speed of the boat were much lower. The skeg and prop and hull have never been bumped. A shower cap was fitted.

Common, what else could I have done?

At the last failure (about 10 miles outside Stornaway) the overheating of the leg/gearbox was so bad that the lube oil boiled out of the overflow reservoir and the intense heat even melted the paint, the makers logo and the serial number off the outside of the leg.

In my circumstances it is very dificult for me to see what my "driver error" might have been. I know you weren't accusing-just musing.

Is this engine a figment of my imagination? see http://www.texasmarine.com/newboats/...vmax_hpdi.html

Thanks for your post Brian as it demonstrates that there is always another side to all problems and also that one persons experience is not anothers.

Calm down Brian,
the issue of driver error is when the drive fails when going into gear, not when running at speed, a lot of people opted for twin lever controlls (a bit racey I think) If the drive is put into gear with anything other than idle rpm's the cone clutch outer parts company with the gear! barrus even insist that the idle is reduced from the factory recomended 750rpm down to 600 to try and reduce the failures, so, if any revving kevin gets it wrong and chucks it in gear at too higher rpm that would be driver error

PS. the higher number of failures with the B3 is probably because the 2 stainless props have a much higher inertia, and they don't have any form of cush drive (rubber hub or flotorque) combine that with trevor the revver and bingo

Sorry Jon-I didn't mean to sound aeriated, honest!!

It is just the whole thing left me nervous about long-range off-shore cruising with that combo. I used to joke that I dare not go on a cruise unless Hot Lemon 4 came along as my support boat!

So now, I have had the Bravo 3X leg changed for a Bravo 1.
We will see how we get on with that!

That egnine look interesting. Are they available on the UK market or do you have to import them from the USA still. twin 250 hp HPDI would be good fun!

Jon just relax will ya,

Brian has come on here and shared some very important knolledge and experience that he has found out about his Bravo 3 legs.Whats the problem with that?

Your saying that you know why it happened. so great,whats the big deal.

I think in my humble opinion that it isnt just how you put them into gear that makes them go.Its other things but I dont know what it is? Yet
