Warning horn

Came on this morning, not WOT, pulled throttle back to idle and it went off. Checked oil and it was full, serviced recently. Any suggestions? Thanks

Sounds like water flo problem, did you put an impreller in when you serviced it??

Temp alarm....Your water pump impellor probably needs replaceing.

Replaced when serviced, top and bottom, good strong stream from hole.

May be an oil injector then, dont play with it. What about the oil tank under the cowling???

4 stroke, 75hp merc

Water separator on the motor? Mine is a 250 merc 4 stroke, has a water separator on the motor that will set off alarm when it has water in it.

You sure? Take off the cowling and snap a couple pics, post 'em up.

If you want to be sure what it is, you'll have to take it somewhere they can hook it to a computer. That will tell exactly what is setting off alarm.
