buddy of mine is a certified merc mech and well know mech on a race team and he said its done all the time to wear the gears evenly. switching the drives from L to R and vice versa...have heard of it a few times...good ? bad ? indiff ?

We do it every year for that reason.....

I'll have to remember to take pics of mine when/if they ever come apart. Be interesting to see how they look after over 1100hrs

OK except with torsional alloy shafts that take a "set" after turning in certain direction with torque applied. Max Machine recommended against switching rotations with their shafts.

Highly recommended!

Why........................?

When they switch a right-hand rotating drive to the left side are they running it in reverse? And vice versa with the left hand rotation? I don't think they're built to run in reverse at the same rpms as they would normally run in forward.

If not, the gears will still spin the same and your props will turn in instead of out, which will change the handling characteristics of your boat.

There is no such thing as RH or LH rotation Bravo drive. They are all the same and made to spin either direction.

The props stay on the same sides they started and do not follow the drive.

I would view switching drives from side to side kinda like rotating the tires on your car.

See this is where my outboard experience doesn't always coincide with the I/O's. The gearcases for an outboard are either LH or RH.

at least you get to use both sides of the gears..sort of like twice the use before they go bang
