Problem fixed: The oil leaks and the trim drops

It is quite old, so it is necessary to replace the motor wiring, but the same kind can not be found in Japan? I am in trouble if I can not find it yet.

My experience was ok but I had to wait 4 weeks to get a water pump gasket for a Mercury outboard. That is way too long. I normally get parts much quicker from this supplier.
by

Problem fixed: No water from tell-tail tube.

The gasket under the water pump wear plate that came in an after market repair kit was the incorrect gasket for this motor. I installed the proper gasket and the pump works fine.

great store i well be back
