This Solenoid is an adequate OEM replacement, at an incredible, low price.
Size: PP67-712 V1
This solenoid replaced a bad 350 Chev. Mercruiser starter Solenoid. It works perfectly with only a minor, simple modification of the mounting bracket . (Hole centers were slightly off needing only 1 new hole drilled on the engine bracket only. A very easy mod.) The Solenoid body itself is an exact match for the OEM and works flawlessly at a price that is literally 10 times less than what the Manufacturer charges.
