Fixed 4.3 Merc IO
Size: 96158T-1PCS
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.
Size: 96158T-2PCS
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.

Great Banana Plugs
Size: 6 Pairs / 12 pcs
I recently purchased these FosPower banana plugs to tidy up my speaker wiring, and they’ve been a significant improvement over bare wire ends. Installation is straightforward: strip the wire, loosen the two tiny set screws, slide the wire in, tighten everything down, and then screw the barrel back on. Once assembled, the connection feels secure and tight, making it much easier to swap gear around and reducing the risk of stray strands causing a short. The standout feature of this design is the dual set-screw clamp. It firmly grips the speaker wire without relying on the outer collar to “crush” it in place. I’m using 12-gauge wire, and it holds well for my setup. Initially, the plugs may fit snugly in some binding posts. Once seated, there’s no wobble, but it might take a bit of extra push the first time. The set screws are small, so a bit of precision is needed. Use a small flathead screwdriver and don’t over-tighten them. Overall, these plugs feel well-made, look clean once installed, and fulfill their purpose as banana plugs: making speaker connections quick, neat, and reliable.
