Hi,<br /><br />I have a 1993 v6 Mercury o/b 175 HP, Carb... It has a ARCO trim motor that burned up on me... <br /><br />History: This is the 2nd problem I've ever had with this motor in 10 years, the 1st was High voltage 2 years ago, I replaced both Voltage Regulator which solved that problem.<br /><br />Back ground: We used the boat for 4 days in a row prior, no issues!(24-30 hrs) Trim/Trailer working fine.. I backed it into the drive way, lowered motor, unloaded and cleaned it up and left it alone...<br /><br />Problem: On the 5th day, late afternoon getting ready to take it out, I found the motor was all the way up and I alway leave it down to drain the water out... I am 99% sure it was down! I pressed the down button on the side of the motor and I just clicked (solenoids)... I put the charger on the battery, that checked ok, and the motor would turn over so it was at full charge. I pressed down from the trim at the helm and still the same result... My guess was the trim or trim motor at that point...<br /><br />I took it apart to find out that the trim motor was fried!! Like the up button was stuck on some how??.. I have replaced the trim motor, but I'm afraid of what may have cause the problem, and that it might do it again??? <br /><br />I have checked both switches, and they seem fine, they both spring back to center position and they don't stick at all.. Checked with a multi meter too...<br /><br />With the new trim motor installed, the switches and solenoids seem to be working as they should (tested, 5 hrs of sking) no issues, no hickups... <br /><br />I plan to buy a battery switch, right now, I am just pulling the + battery cable... The motor cost too much to chance it!!!<br /><br />My gut on this is: 1. the up solenoide engaged with the sun beating down on it. or 2. someone held the button too long and burned it up.. (I have a retarted boy who visits next door, and has been caught playing in my boat before, so.. <br /><br />Normally the boat is kept locked in the garage, so it out of reach of the sun and the boy next door, but while on vacation, I was leaving it out cause we were using it everyday...<br /><br />Any one eles had a problem before?? <br /> <br />As a precaution, should I replace the Up solenoid?
