I am restoring a 1975 SRV180 and had it painted during the winter. I took it to the lake for a quick test drive and found that the drive will not go into forward (it worked just fine before I winterized it). The paint shop did no disassembly other than cosmetic stuff. The engine stalls as soon as I shift from neutral into forward. Reverse works just fine. I acquired a shop manual and began troubleshooting. I thought I would go through the shift cable adjustment procedure and discovered that when I shift to full forward, the clutch does not engage when I turn the prop counterclockwise. It engages in reverse just fine. I disconnected the cable and moved the shift lever (at the motor) as far as it would go each way. Reverse engaged just fine, forward would not engage. I'm not a mechanic and would very much appreciate and suggestions on further troubleshooting techniques. Thanks much.
