I have had a couple of issues with my 2003 motor recently. I thought the battery was dead since it would not turn the starter when the switch was engage but a new battery and cleaning the connections made no difference.
I finally got it to turn over and it started right up. I decided after playing with the switch that it appeared to be an intermittent problem and most likely an issue in the ignition switch. I replaced the switch yesterday and thought my problems were behind me.
I took it to the lake this afternoon and after running the engine for about 10 minutes I was cursing down the lake at about 3000 rpm when the temp light and horn came on. I brought it back to idle and checked to see that water was flowing out of the cooling overflow, it was.
I cut the engine off and pondered the situation, then decided to check the switch to see if anything was shorting out or loose since the temp warning light and buzzer are in the wiring bundle that I pulled on yesterday while changing the switch. I found no problem and the light/buzzer continued to come on as soon as I turned the switch on....even without starting the motor.
After about 20 minutes I decided to limp it back to the dock. I made it back fine with no indication of the motor heating...other than the warning system. I trailered the boat home about 10 minutes from the lake and when I tried the motor at the house the alarm was silent. I started it with water hooked to the intake and ran it for 30 minutes at various rpm's with no over temp alarms. I started and stopped it several times and never got the alarm again.
This motor probably has less than 100 hours on it, I bought it new and it has always been stored on a trailer and only run in fresh water. I checked the intakes and found no indication of blockage. Water comes out the outflow normally and the water felt cool the whole time it was running.
Any suggestions on what to check or how to be sure if it is an indicator fault or actually a heat issue?
Thanks,
Forest
