Used it in a pinch for stater relay... it works great. Be aware... Mine required metric sockets for the nuts... 10mm for large terminals - 3/8 was too tight and same for smaller terminals 7mm fit better than 5/16 that was too loose. The mounting holes are also spaced closer together than the OEM on a mercruiser 260 in a mid 1980's boat but easy to remedy with a 1/4" drill bit.

Engine wouldn't start reliably or consistently. I had no clicking either from the old solenoid even though it would start from time to time...motor starts perfect after install. Pretty easy install as long as you reconnect the right wires. This worked perfect!

Did not work.

I went to double check that I can read but it says 35hp-275hp and it sure didn’t work on my 200ho mercury so I do not recommend. If you’re on a time crunch don’t push your luck buy OEM like I am doing right after this review.
