More prop/drive questions - for the experts
 

I've been talking to a friend of mine that has been breaking Bravo drives about props. I've been running the same 96 Bravos behind my 41 Velocity for about 10 years, 7 of those years has been behind 600 hp motors. I spend a lot of time in the ocean, but other than taking 1 tooth off a gear in 00, I haven't been breaking drives.

I was wondering if it had to do with the props, I run labbed B1 props but I did cut the diffuser ring off. Would that provide enough slip so the drive doesn't get hammered? Or is the RedLine Heavy Shockproof oil just that good?

What pitch props are you running? Do you use a drive shower? Are the motors N/A or S/C? What is yout top speed and rpm?

28P, drive showers, NA motors, 5600rpm on a good day, top speed, mid 80s on speedo.

A couple of years ago I did a survey of owners with broken Bravos and what was found was that drive showers, external steering, 26-28"pitch or less props, synthetic drive lube were ALL benificial. In fact, none were broke with all the above. Your N/A engines have less TQ than S/C motors and that is good for not breaking drives. So you have all the right things to not break a drive.
