I run a 1992 175TXRQ Yamaha with 580 hours. Great motor. The previous owner disabled and removed all major components of the oil injection system for reasons unknown to me. Two trips ago the alarm sounded continuously and the motor dropped into safe mode after about 15 minutes @3200 rpm. On the tach, a pointer was flashing above the "low oil" indicator. (I remember it dropping into safe mode last year while running at full throttle, but I don't remember which indicator was flashing that time).
I researched this forum and read many posts by Rodbolt explaining the basics of the system operation. I found a similar problem described, and tried to duplicate the solution. Bypassing the reserve alarm was accomplished by jumping the black/red to the black at the connector in the bilge. The "full" indicator now shows a constant pointer. But I could find no white/red or black near the location of the engine-mounted tank, which is now missing of course. While searching the wire bundles for these colors, I found a pink wire on the stbd side of the powerhead which was corroded completely through. The wire leads to a brainbox of some kind mounted on the rear of the powerhead, maybe 10 in wide and 14 inches tall, with the emergency oil transfer toggle on the port side.
I repaired the pink wire and we took it for a ride yesterday. After 25 minutes at 3200rpm, the alarm souned, dropped into safe mode and all three pointers were flashing above the three oil indicators on the tach. We shut down for no more than 5 minutes, and restarted. We ran the motor for another 30 minutes @ 2500 rpm, no problem. Later that day we ran for 40 minutes @ 2900 rpm with no problems.
Near the location of the engine mounted tank, I can only fiind light blue wires, and a small (1" x 1/2" x 1/2") encapsulated component with three wires leading to it just lying next to the powerhead.
Can anyone take an educated guess what I've missed? I can only assume that the previous owner bypassed the primary tank sensor and the crimp has corroded, but I'm apparently looking for the wrong color wires.
Thanks
