These are the 12 volt pumps on the remote tanks.What is a secondary oil pump?
I think there are two pumps, one mechanical on the motor itself and one electric on the remote oil tank. This assumes motors are SX models
I am in lewes delaware....what are you asking for your 2 pumps?I am repowering and I have to remove my remote tanks. I replaced both pumps about 2 years ago. Bought them new from SIM Yamaha. It’s gonna be a week or two until I get my hands and them, where are you located?
Thanks I have removes and tested both pumps and they do not spin when 12 v applied.Before you replace the pumps, are you sure they or it is bad? There are diagnostic steps to determine whether they are working correctly. Most common issue on the oiling system is clogging of the inline filter on the back of the remote tank. The tanks also can collect oil sludge. If you are sure the pump is bad that good but if you are not, you need to troubleshoot efore replacing the quite expensive part and then being disappointed.
