Broken 20-Ampere Fuse Holder

Postby PATXBill » Sun Jul 23, 2017 9:00 pm

I have a 1987 Evinrude 225, E225TXCUB on my 1984 Outrage 22. I've been trying to track down a very intermittent starting problem--intermittently the engine won't crank. In the process I damaged the 20-Ampere fuse holder on the port side of my engine. The connection was brittle--ironically, the fuse was intact--and when I opened the fuse holder, I inadvertently tore out the wire that connects to the top ring of the fuse holder. Is there any way to correct this? [A way to] splice a new fuse holder?

The fuse seems extraordinarily seated in the fuse holder, and it may in fact be corroded together. Advice welcome!

Replace the 30-year-old fuse holder and fuse. Use a modern in-line fuse holder. Look to BLUE SEA SYSTEMS for an appropriate fuse holder. Install the new fuse holder by making in-line splices into the circuit.

The best forum to discuss electrical problems encountered on small boat is the SMALL BOAT ELECTRICAL forum.

Also, most Evinrude outboard engines have a 10-Ampere fuse for the ignition key and accessory circuits. Double check the engine service manual or operating manual to verify the proper rating for the fuse.

Thank you, Jim. Your response confirms what I thought, but wanted to ensure I didn't damage anything further. I very much appreciate the link to the Blue Seas fuse holder.

I have the service manual and have been performing all of the tests indicated. I have examined the fuses and will check again and replace. The intermittent nature of the problem leads me to believe it is a bad ground somewhere, but I have checked and cleaned all of the ground contacts I can find. I will continue to investigate.

Any updates will be posted to the Small Boat Electrical forum. I was unsure which forum to post, I now realize that the Small Boat Electrical is not limited to accessories, distribution, etc.

Just wanted to thank JimH again. I replaced the corroded stock fuse holder with the Blue Seas product Jim recommended. I also rechecked, cleaned, and tightened all grounds. Engine fires up reliably now, and noticeably quicker. I believe the deteriorated fuse connection was the cause of the intermittent failures. I am now turning attention to an overheat problem that occurred on my test run. That will be in another thread if warranted.

Hi Bill--glad to hear you got the new fuse installed and the effect was positive (to make an electrical pun).
