Have an older Mercury 40hp 2 stroke. This Solenoid worked perfectly. It is not that easy to install, due to the design of the engine. It does require a bit of patient and the right tools to do it. If you have big hands and don't do this type of repair to often, call a friend that is better than you to get some help :) I have an older engine but it runs like charm. I will order an extra Solenoid and place in the box of "important spare parts" for the future. Very good experience for the purchase and overall quality of the part.

Perfect fit and works great

Size: 96158T-2PCS

Perfect fit and works great. It is great that it comes as a 2pk. I replaced both with no need to change wiring, and kept the working one I had, as backup.

It works as it should...

Size: 96158T-2PCS

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.

Fixed 4.3 Merc IO

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!
