Engine Test After Bottom Scrub

You can see by the max speed (3.1 Kts) that scraping the barnacles off the waterline may have had an effect. Also tried reverse and she seemed to rev high, with no carbon discharge and move a lot of water. I wonder if the transmission is not fully engaged in forward due to the fact that I'm using a reconditioned transmission cable that isn't quite long enough. Next time out, I'll remove the cable and manually shift.
