Seaswirl schematic

[cudajim1]

I need to find a schematic for my 1987 Seaswirl Temp Sport. The horn is not working due to low voltage (around 9v) when I push the horn button, which isn't that much current. I need to know where the big fat red wire is getting its connection way back at the engine. I seem to have a voltage drop somewhere along the line.

the switch and gauge wiring will be in the motor factory service manual. schematics for the boat never existed.

you most likely have a bad connection.

Ok so where do I get a motor factory service manual?

Thru the dealer or the company that made your motor. Can't help you beyond that because you have not stated what motor you have.

You will find service manuals for engines, but nothing but owners manual for the boat itself. Very rare to find any type of wiring schematic for a boat.

The engine is a Chevy V6 3.8 litre.

No, the engine will be OMC or Mercruiser. the base components may have come from GM. but the schematics, electric, etc. is all mercruiser
