The prop is a new stainless prop, with no signs of damage and it vibrates in neutral ,on the hose , sittin in the yard . Ive almost ruled the drive and prop out. I can reach over and behind the motor and grab the drive input shaft and shake it around inside the coupler, so im thinking thats gotta be the culprit. This old 77 V has alot of room around the back of the motor but I think Ill just pull the motor completely out ta change out the coupling. Looks like I gotta pull off the engine bellhousing to get at the coupling bolts and ta get it out of the bellhousing hole. It won't be to bad of a job being I already had it out before. Probably can do it in a day (I hope).Thanks for all the info fellas! Ill let you all know how it turns out.
