I removed the galley of my '77 Catalina 30 in order to replace hoses, clamps, check and tighten etc as preventive maintenance. I installed a new heavy duty Morse Cable clamp on the transmission shift cable and started the the Yanmar 2GM (13 hp). When I started it and shifted it to forward it did as it should, then to reverse and again OK. However when I put it in neutral it was in forward. Adjustments made in the cable position but no change.Disconnected Morse Cable and shifted by hand. Click it goes into forward, click it goes into the neutral position but still going in forward, click into reverse and reverse it is. There is a small "sweet spot" between forward and neutral where the shaft does not turn however it is not where it should be at all and using the cockpit shift lever it is difficult to find without watching the shaft coupler.Has anyone ever experienced this sort of problem? Feel that I may have to pull the trans this weekend and drop it off at the marine engine shop.
