I've got a 1998 ox66 225. Last trip out about 20 miles out, we started up to head back and when we pushed the power forward it started clunking in and out of gear. Engine running fine, just not engaging fully. Quick fix, we disconnected shifter cable and manually threw it in forward and off we went. Got home and adjusted the cable. Started going back into to gear normally but then would take a lot of pressure to get it in neutral. Reverse operates normally. Took it out on lake today to be safe, popping out of gear one again. Ideas anyone????? Please help!!
