where's my 50A main fuse

I have A 1989 Sea Sprite 1900 and am looking for the 50A fuse that supplies the fuse block. I was thinking it would be up under the dash but after tracing the wire I had no luck. I did not know if it would be an inline fuse.
Thanks Jim

What's the engine?

Mercruiser I/Os have a main circuit breaker near the connector that connects the harness to the engine. The harness contains a heavy wire that runs to the helm and connects to the ignition switch. From there, most power to the accessories are individually fused from the ignition switch connection.

Are you having problems?

Thanks Rick, I'll give it a look.
I had the boat out for about 4hrs on the river with no problems. When we were trailoring the boat we hit some mud in a shallow area and the engine cutoff. Went to restart and the nothing happened. I tried the blower and pump and neither one worked. I checked the battery connections thinking they may be loose but they seem to be fine. I tried the trim which did work and is on a seperate 50A fuse.

Rick,
I found the fuse. It was on toward the back of the motor on top.
Thanks for the help.
Jim

Glad you got it fixed. Was it a fuse or the red button circuit breaker?

It was the glass fuse. It had the 50A fuse for the trim right beside it. If I would have known that I would have just swapped them out in the water and not had to paddle the 20ft to the trailor.
Live and learn.
