While winterizing my boat ('90 Forester Diva 1800) today I noticed that the plugs were showing signs of wear. My plan is to get new plugs now, and store them with the boat key so I don't forget to change them next spring when I pull them to clean out the fogging oil.
My manual recommends Champion QL77JC4 or L77CJC4 @ .040, or QUL77V for sustained high speed. I have three questions about this:
1. What is considered 'sustained high speed'? I don't troll with the motor at all, and I occasionally take my grandkids out tubing for an hour or two. Would you recommend the QUL77V for this?
2. All the current charts I've seen show a .030 gap for the Q/L77JC4 plugs. If I stick with this plug, should I be using this instead of .040?
3. None of the spark plug charts I've found online list the 110HP motor. They all go from 100 to 115. Should I feel left out?
Thanks.
