I have a 2001 150 hp evenrude. The manual I have does not specify the plug part number or the plug gap. The engine came with Champion 955m XC12PEPB.
Is this the correct plug for the engine? What should the gap be? Someone told me the plugs have to be oriented in the right position. Is that true?
Sometimes after a few miles of running at cruising speed I get a check engine light and sonar alert. I just shut it off for a minute and start back up. It will often run another several miles before I get the alert again. Sometimes I can go a mile and more often I can go 20 miles without another alert. It is so random I don't know what to make of it.
The plugs seem to carbon up sooner than I'd expect. I have been sand blasting them and putting them back in. Is this worthwhile?
I have been using TCW-3 Evenrude oil since it was new. I was just told that I need to use Evenrude XD50. Is that true?
Thanks in advance for any responses. Mike
