Someone posted awhile ago that their motor would not get full power but with different plugs,not the champion, would achieve full power. My plugs are RL86Q, not C. Could this be a problem? They are champion plugs also.

What is the model number of you outboard? Not all models use the same plug.

Re: 84 evinrude spark plugs

When I start the motor and pull a plug wire it stalls. Iput in new condensers thinking that was the problem. Wrong. Where should I go next. P.S. It does seem to run better but still not right.

OK. I hate to ask, but is the compression sufficient?.

Re: 84 evinrude spark plugs

With a compression gauge. It has a specific purpose. It measures psi in your cylinders. Can get at any local auto parts/wal-mart store for about 15 green backs. Do this first and post back results. A friend that work on motors may have one you can barrow!
