Direct replacement on my 95 SeaRay 175
Size: PP67-712 V1
My boat started to have issues with not turning over when I used the ignition switch. Replaced the switch and had no effect. Replaced the solenoid and that fixed the problem. Good price, so I replaced all 3 solenoids (Trim/ starter). Solenoids had all needed hardware (nuts/washers)

They Fixed My Boat
Size: PP67-712 V1
My boat wouldn’t start, and the outdrive wouldn’t go up or down. So I bought three of these solenoids and replaced the starter and both trim motor solenoids/relays. Now it starts right up with no problems and the trim motor is working again also. I have a 2006 Stingray boat.

Poor quality
Size: PP67-712 V1
Poor quality. Replaced a starter solenoid on a mercruser 4.3. Right off install it would click but not make a connection to start motor. Confirmed this was the culprit by jumping the terminals. After testing multiple times found it worked a little less than half the time.
