need to find oil pump

I have a 1988 Yamaha model #V6EXCELXG Serial #701268. I was told that my oil injection pump needs to be replaced as it is passing 2 cycle oil when trailering the boat. This part is discontinued through Yamaha. can anyone tell me where to look for an oil injection pump?

the oil pump on motor wont put out oil until motor is running, turning the pump

you may have a bad oil control unit or sensor but doesnt sound like a inj pump

oil pump

I think the oil is leaking out the shaft seal into the crank case then coming out the lower carb or the crank case vent hose that goes to the intake. so you can't fix the seal
