Blowing 90amp fuse on my Mecruiser boat motor 

It’s located on the starter motor, not the alternator. Good video though 👍

That would be the starter my guy

is it possible for the engine to start and still run if this fuse is blown?

You say it's on the alternator, but it's not, it's on the starter solenoid. I have lost volts at the helm so am looking into this fuse, just trying to get access as it is not easy to get to!

Thanks for a great video. Helped save me a bundle of time

so why did it blow??

I just discovered I had this issue and going to replace it this weekend. I mapped out all my wiring and with no power at the ignition key or at the starter relay input this would be why as the red wire here runs up to the circuit breaker and then over to those two items so I am sure this is it. Great visuals on the video to show this!

Hi mate is this the correct fuse for omc cobra 4.3 many thanks

I know exactly what blue mine I don’t leave my boat running when there’s kids in it and my friend left it running. I accidentally tried to start it twice while it was already running. 😂😂😂 once I turned the boat off it would not start again replace the fuse. Everything’s fine don’t start your boat when it’s already running. 🤣🤣🤣

We’re there 2 cables connected to the battery side of the fuse?

It would be nice and if you could see what the video was showing you

Is it hooked up to the alternator or starter?
