anybody know this ? why is it when im flushing my starbord engine my prop spins, when i flush my port engine it does not.

IS THAT A PROBLEM.

what transmission?

velvet drive, borg warner

Could be adjustment of the shift linkage different between the 2.May just be the clutch plates are a little tighter in the one.Probably doesn't do it in the water. I wouldn't worry about it though.Mine tries to spin a little when I run it on the trailer.

My BW trans with a TRS will also slightly turn the prop when in neutral and flushing the engine with it on the trailer. Like stated could just be a tight clutch pack.

If it is a stock un-modified transmission it is usually that the forward clutch plates are starting to warp.

thank you!
