Ole Evinrude

5 posts in this topic

Looking for alittle help...Got an old evinrude, 89, when i start her up, and she starts like a dream, the alarm in the controls goes off and stays on, this is on my pontoon. I am under the impression this is an over heating alarm???? The alarm comes on right away so there is no time for it to over heat and she is pumping water out real nice... Someone said it could just be the sensor, could this be? and where is the sensor housed.. Just can't afford the ninty bucks an hour to have it looked at!! Thanks guys for the help.

What horsepower? Is it oil injected? could be the oil injection/fuel pump (VRO). To eliminate the overheat warning, look for the sensor on the back of the block. It will have a tan wire connected to it. While the horn is sounding, disconnect the tan wire. Horn quits=bad temp sensor. Horn continues, it's coming from the VRO.

Ok, much easier to trouble shoot. Just do what I suggested then in regards to the temp sender.

it is the temp sensor most likely it is crounded somewhere, or its shot look for a tan wire comming out of the head bout 2" away from spark plug..and dissconect the connector trun on ignition if its quet the sensor is bad if it keeps buzzing look for a short somewhere.. ive had one that a mouse chewed on and it drove me insane trying to figure out why it wouldnt shut up!
