Installed in my RV.
This product works well. It is somewhat difficult to mount. The contact points are a little too close together. These deficiencies are understandable given its low cost and small size.

Inexpensive part and YouTube knowledge lead to quick fix
Size: 96158T-1PCS
Solenoid went out on boat. After viewing multiple videos on YouTube I figured that my solenoid was bad. Ordered this and received a day later. Replaced the other one and this worked perfectly.

Worked perfectly!
Size: 96158T-1PCS
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.
