Weird ... 1996 OMC 60hp, new to me, but had been running on a buddy's boat. He kept his harness for his new motor. I bought new harness and installed the motor, all connections appear sound and 'no leftover' wires or connections anywhere.
Only I did was disconnect the VRO2 system. Yes, these allegedly are supposed to be bullet-proof on these models, but 2 things influenced my decision: (1) No room in the stern of my skiff for the oil reservoir and (2) I run other skiffs with OMC tanks and connections - that are pre-mix - so I was thinking if I was in need of fuel, I could just grab another full pre-mixed tank.
Anyway, I do have the OMC original OEM service manual and capped off the VRO2 system as stated. Motor started and ran on muffs in driveway, with no alarms, but I know better than to diagnose things when running on muffs. I do get the confirmation 'self diagnosis' beep when the ignition key is 1st turned to ON.
Launched (finally!) for this season on SAT and 15-mins into the motor running at high idle (1000 to 1200 RPMs) at the dock to warm up, while I did other chores to get ready to set out ... and I get an intermittent warning horn BEEP every 1-1/2 seconds or so. Wot the .. ??? As per my service manual, this motor only has 3 alarms - overheat (SLOW mode, constant warning horn beep, low oil (short beep every 40 seconds) and no oil (continuous short beeps). With the VRO disconnected, I should have zero alarms.
So it appears I have a phantom 'no oil' alarm. Any ideas? I tested the overheat alarm circuit by grounding the OB-side of the tan lead from the powerhead to the block with the key ON and it sounded continuously as it should.
... I admit to being kafuddled ... w/ service manual and all ...and I've been around OMC motors for 40-years ... LOL.
