    Fit my Mercruiser 3.0 and works. I replaced the alternator and forgot to disconnect the battery. Likely touched some wires and blew the 90 amp fuse, this one fixed it.

    Worked perfect for my bayliner capri 185 with a mercruiser 4.3

    After making the unthinkable mistake of reversing the battery terminals, the boat wouldn’t start and none of the electronics worked. The hard part was finding where this fuse was; changing it was easy.

    Works as should, just a side note make sure you check out the starter solenoid that’s on your actual starter before replacing this. It could be a bad solenoid and not the actual fuse.

    Yeah, me too. This fuse blows fast, don’t it? And the sparks? Whew! This will fix it though. I bought mine with a battery switch. 😉

    The fuse was bad but I didn’t find out until after the return window closed,
