If there's no play in the propeller shaft, it'smore likely the seal below the impeller. Go,to Boatparts.net for an exploded view of the lower unit. Not to tough a job for the average Joe with a couple of wrenches.Rg
Take that thrust washer of the prop shaft and you will see the seal behind it.The thrust washer has the numbers embossed into it.
Thanks! Should I just pull, twist, or what? What should I see in there?
There's no play in the prop shaft....boatparts.net isn't an active website...I'm up for DIY if I can get the right info...I do have some wrenches, but not much knowledge of motors and don't want to make things worse
