Fully gold plated inside and out! I initially got the amazon basic connectors for the same price, but was disappointed in the tiny burgundy positive label they had. It was also very dirty inside the connector and it wasn’t gold plated through out the connector. These are excellent in quality and have a bright red ban on the connector! You wont be disappointed and beats out Sewell connectors for the price!

Decent, but be careful of frequent use.

Size: 12 Pairs / 24 pcs, Size: 12 Pairs / 24 pcs

The looks are very nice, functional if left alone once assembled. After that I would leave them alone otherwise you risk the main male portion just coming loose of the housing, sound quality is decent, nothing to write home about, but again, not very durable. If they could fix that 1 thing, these would be very good buy and value, the rest of each plug is hefty and well made.

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.
