Getting no power to the boat

[Jerry12179]

I have a 1999 Maxim 1900 SR. I was changing the spark plugs and hit the starter which made a spark. I now have no power go to the fuse box. I tested all fuses including the inline fuse by the battery and they all fine. I am getting power coming out of the battery after that fuse. Also my trim motor is working fine but that is it. I am wondering if anyone knows if their are any other fuses that I dont know about. Any help would be greatly appreciated.

Re: Getting no power to the boat

I dont know if this helps you, but I accidently popped a fuse on my outboard and though it was the fusebox fuse.......well ended up being a 30amp fuse inside my motor underneath the cover twords the back. It was hard to see because it was a very small mini fuse and holder. Hope this helps.

Ayuh,.....

Your boat might be New enough to have the little square Fuse mounted on the Starter......

If it Does,.... Take it off,+ give it the "Float Test",....
Then put the Wire directly on the Starter Lug......

Re: Getting no power to the boat

most later model mercruisers have a 70 or 90 amp fuse on the positive battery cable starter lug, shame on Bondo for advising to ditch a circuit protection device. . if yours has it and it poped it means it did its job and prevented further damage.
yours also may have a 50 amp resettable breaker, usually mounted near the engine harness connector.
but no never ditch circuit protection. some years back my friend had a Toyata truck, had a short in the headlamp circuit that kept tripping the breaker.
one night he cut a small piece of copper tubing and installed it to get home from work.
truck burned to the ground on 174 near godly TX.

If you found all the fuses,and all are good....then you might of fried the Electronic ignition,i'm not sure,but i do know its a very sensitive piece of electronics,so if you have the owners manual check all fuses,and if there is still no power to the starter,try the solenoid,if no luck there,buy a chiltons and do a process of elimination,As you already figured out,disconnect all batterys prior to doing ANY type of electrical work.Good Luck.

Re: Getting no power to the boat

what did you drop to cause the spark and where?
battery cable check- do you actually have power going to the starter, jump out the starter solenoid. if that works ,you have power to there, if it dosent ,you have a bad battery cable connection pos and/or neg.
starter works, key dosent- check that plastic looking square thing on the starter ,a fuse link.from there power goes to the 50A breaker mounted on the engine.

Here is a picture of the fuse. It bolts directly on the large terminal on the starter.
