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.

Low quality. Recommend something from a better brand.
Low quality. Seemed fine until the first one I ordered one of the terminals broke off with very little tightening force. The replacement i had ordered worked for a few days then quit working altogether. Overall disappointed.
