bravo 2 or bravo 3 legs

Help Chaps please,

I am building a new 11m rib, upgrading from a 8.4 with a 300hp yanmar coupled to a bravo3x drive leg, had no problems with the engine but the leg was a different matter, had one go after 50hrs!

Thinking about using the same engine but this time with a bravo 2 leg !! are any rib net members using the yanmar 300 and the bravo 2 legs..........comments would be greatful..THANKS

11 metres! ooh wow, lots of photos please.

Just a thought since you are hardly going to be trailing it anywhere and its going to spend most of its life on water why bother with stern drives? why not go straight for a drive system similar to those on a gin palace? with props and rudders under the hull.

We hope to get a top end of 42kts giving us a crusing speed of 35kts......had considered the new 421 yamahas, 270hp, but have had some bad reports from a couple of owners...and have little knowledge of the new d6 volvos.....it seems all the engines are up to it but not the legs.

Go for the D6. Common rail is the way to go and the D^ is a brilliant engine.

Do you have personal experience of the D6 and its drive, simmons0?

I think Mike Garside put a Bravo 2 on Mag Alpha when he re-engined with a Yanmar 300. I know that Brian changed from B3x to B1 after two B3x failures. Might be worth pm'ing Brian for his advice.

RIBase
I would give Joe Poulter at Barrus a ring.
An 11m boat with one Yanmar is not too likely to exceed 40 knots and therefore I believe one Bravo 2 with a large diameter (not pitch) prop, may be the answer. If two Yanmars are employed then 40knots is quite likely to be reached in which case I suspect that Bravo Ones could be the answer.
But why not ask a professional?
