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.

Great Banana Plugs!
Size: 6 Pairs / 12 pcs
These FosPower banana plugs work very well. I have used dozens of these great FosPower banana plugs over the years, and they definitely work as advertised. When comparing apples to apples (or bananas in this case....lol), all Banana plugs work virtually the same way, and these banana plugs are no different. Strip speaker wire, unscrew banana plug cover, loosen speaker wire retaining screw(s), insert speaker wire, tighten speaker wire retaining screw(s), screw on banana plug cover, and wallah, a secure/conductive speaker/amplifier wire connector is created. Albeit, some banana plugs require the speaker wire to be splayed over a hollow post, and then they are held down by a screw-on retainer/cover. However, I much prefer these FosPower dual retaining screw type of banana plugs for their speaker wire holding ability. I always use high quality 14 gauge OFC speaker wire with these FosPower banana plugs, and they work perfectly together. I have used these FosPower banana plugs with many different speaker and amplifier brands over the years, including Klipsch, Pioneer, Polk, Denon, Dayton Audio, and Fosi with no problems at all. They just work, and work well. I have never had a FosPower banana plug break, release the speaker wire or short out, in all of the years that I have used them. Yes, these FosPower banana plugs do fit rather tightly into the connectors, at first, on a lot of speaker and amplifier brands/models. However, after the initial "squeeze" the banana plugs will lossen up, and become easier to install and remove. However, they still retain their great holding ability even after the initial squeeze. In order to overcome this initial "tightness," I usually just stick the FosPower banana plugs into a connector of an old portable amplifier, before assembling them, in order to squeeze them before inserting them into their final speaker or amplifier destinations. This is especially useful when working in tight places, where there is not much room to work in order to push the FosPower banana plugs into their tight connections firmly. Overall, I highly recommend these FosPower banana plugs. I am currently using them all over the house and shop for home theater and music listening (and testing projects). Just be aware of the tight fit in some speakers and amplifiers. Also, the 2 very tiny speaker wire retaining screws can be a challenge sometimes. Just use a good standard blade jewelers screwdriver, and be careful not to remove the retaining screws all of the way or over-tighten them. Once these things are mastered, using these FosPower banana plugs becomes second nature. Have fun!
