any issues running a counter rotating engine for a single engine use?

My 92 Yammie is counter rotation. No issues with it other than the feeling of torque in a different direction.

Do CR outboards have one more gear or one less to make em turn the other way?

[phatdaddy]

same, just beveled backwards. i was also told some eariler models used the reverse gear in the forward position and this is why some had premature failure, reverse gear was not as "beefy".

as far as I know, they all(CR units) use the rear most gear as fwd gear rather than the front side gear as fwd(confusing isn't it). The counter units use flat torrington bearings to support the load rather than tapered bearings, OMC units didn't really change that much as they allready use teh torrington bearing. The flat bearing is supposed to be better than a tapered roller. I do know they are a pain to set up, and they have closer tolerances, I think incorrect set up may be the main cause of issues with them

Ugh!.... lol All the good motor's i've found close are all counter rotators...

i'd be more worried about what they came off of rather than it just being a counter, if it was the twin to a pair of offshore engines pushing a heavy offshore boat to the Georgetown Hole and back twice a week, something made them think to repower. Or if was a loose motor that ended up being rigged at a dealership( it happens more that you think) then its no big deal, just watch out for corrosion and check the play in the steering shaft, make sure your not gettings some one wore out motors off of their tournament boat.

Got a lead on a yamaha down in Hilton Head right now. It's at a dealer that had someone come in and repower. Also checking out a 140 evinrude in the upstate sometime too. I'm definitely learning patience in this process...lol
