Hi all,

I am trying to identify a part that came on my boat. It's an 88 procraft. We went fishing (after MUCH rains) and the boat runs fine (and has been).

We started the boat up after fishing most of the morning and it started 'buzzing' loudly. The sound is/(was...I'll explain in a minute) coming from this black circular speaker looking thing.

We screwed the terminals down that connected to each polarity (black and red) and the noise stopped. Since then, my speedometer now works, when it didn't before. The engine still is peeing, no smells, and doesn't appear to be getting hot.

Is that "speaker" a warning for something else (like heat), or for the speedometer, or for the impeller, or an aftermarket horn etc?

I ask about the horn part because it took me 6 outtings to discover where my horn was. It's the old push button kind, and it was painted over to match the boat, so I never saw it.

It's about 3 inches and only has ground, positive, and then a wire which I guess ties into the electrical system maybe? This part looks aftermarket. (i.e. it just hangs from under the console).

Yes I am sure I'll get 10 replies stating to have it checked, but I don't want to pay the $65 an hour to have something looked at, when it may be nothing....follow me?

Thanks for your help.

If the speaker you are talking about is your horn then i would suspect no problems.   It could have shorted out from corroding wires and started making the buzzing sound.  Dose the horn work now that you have disconnected it?  if so then you disconected something else.

If you had a picture it would make this easier.

I didn't disconnect anything. The horn works, this is completely seperate from the horn. My horn is 'glued' into the hull, this is something hanging down. I have a picture I can post tonight.
