Location: Eau Claire, WI | I'll second what Baldy said. Bad gas has a certain odor to it, you'll know it if you ever smell it, almost like turpintine.
Add a can of Seafoam, fill the tank and run it down to 1/4 tank and from then forward always ensure you use a fuel stabilizer. Additional additives you may want to cosider once or twice a season depending on how much you use your motor are: Seafoam, for fuel system and top cylinder cleaning and lubrication. Ring-Free to help prevent carbon deposit build up on the rings. This applies to both two and four stroke motors.
I personally use Seafoam every other tank and one bottle of ring-free per season for good preventative maintenance. You can purchase Seafoam and any auto parts store, most marine dealers, and Farm & Fleets. You can purchase Ring-Free at most marine dealers since Yamaha and Merc recommend it's use.
Merc ELPTO 60's and 75's have been great motors, very reliable and good longentivity. If it's a four stroke, it is most likely a Yamaha power head in that era. They too are good motors.
Hope this helps. |
