Hi Bob,
I worked out the reverse gear thing on my ob343140 60hp merc. Was off one spline on the upper shift rod.
The thing I need advice on is the warning horn problem. The motor was overhauled last winter and the first thing on the water was "over heat/oil" warning. There was plenty of water coming out the pee hole and no steam so I can't believe it was hot. It never came on untill the rpms reached around the 5k mark. I tried to keep the r's down for break-in. The motor ran sweet and smooth and if the tach was right had plenty of r's left like the prop might be pitch too low. My heat sensor wire goes to a grounded lug on the block which seems odd to me but that's where it was. I pulled all the plugs this morning and they were all clean. Does that mean water in the cyl? I have a 25:1 oil mixture. Also I pulled off the Autoblend last winter, do I need to unhook a wire somewhere? The motor purrs like a kitten and has lots of power it's just the warning horn. Someone said if exaust is getting in to the water jacket (cracked block) it would heat up the water and set off the horn. Any thoughts on that? I would expect the motor to miss if that was happening. I am baffeled . Any help>...............Jerry
