"I'll try to keep the question short and I would appreciate any/all response!
My 1999 50hp 4-stroke Evinrude has about 100 hours on it and I ran it yesterday for the first time since 2007. Just before putting it away in 07' I had the plugs, LU, oil and filters changed. I put fresh gas in the tank yesterday (93 grade) and it sputtered for a bit but ended up running great with the exception to my topic....
Prior to storing it, the overheat sensor used to sound, indicating that the engine was running hot. I had it checked and the thermostats were replaced but noting was found. The motor pees good and the water is warm to touch but not scalding. Once you kill the power, you can crank it back up and run for 10 min. or so until the alarm comes back on. While running it yesterday I noticed that I could run for longer periods of time if I kept the RPMs below a certain range (5000 to be exact). If I ran btwn 4500 and 5000 the alarm would not sound, but if I ran it any faster, the alarm would go off and I'd have to restart. Does this sound like an electrical problem or something internal. I had forgotten that the motor also did this before I stored it back in 07', so it is not anything new. I don't want to run the risk of damaging the powerhead if at all possible and was looking for some helpful advice. Also, even though everthing was replaced before storing the motor, I went ahead and put in new plugs, filter, etc. before running it over the weekend. Please advise.
Thanks,
Jason"
