The Bravo drive saga will I think never be resolved.
Some people swear by them some swear at them.
I was fortunate to spend some time on holiday with a few commercial RIB operators is south wales, a great bunch.
To sum up there comments,
Typical Ribs 9M with Yanmar 300's
Typical use, 12 hours a day, 7 days a week during the summer months.
Bravo 3X multiple failures they dont think this is suitable for commercial work loads
Bravo 1X, never tried
Bravo 2X, now using and to date much better.
However they said they would look for alternatives to the Bravos for future RIB's.
Anyway based on this I have gone Bravo 2 for my new RIB.
While I know is not as quick as the Bravo 3 it does appear to me more reliable.
It would also be interesting if people know if adding showers makes outdrives any more reliable.
