Brushes for Oildyne Pump

I have a 1985 oildyne pump on my Mercury outboard for a power trim unit for my boat. The brushes in the motor are a copper composite and about 3/8 of an inch square and one inch long. The unit will no longer work because the brushes are worn out. No one in town has the brushes. There is an Intertech corp. logo on the motor housing. Can you please help me find some brushes?  The motor is in good shape.  I was told that graphite brushes will not work in that motor.  Don


Our local auto starter repair shop fixes them. Some Mercury dealers handle Sierra parts and they have replacements. Check if your local dealer can get you the brush kit.
