How do you troubleshoot an outboard that seems to be alternating from using 1 cylinder to 2?
My 25 hp evinrude seems to be shifting back and forth between using one and two cylinders when given full throttle, but works fine at slow speed. What might this be? How do i find out if that's the problem? and how do i fix it?
Trouble shoot by starting with the simplest changes.
Replace the spark plugs with the correct type and heat range for your year model engine. Champion QL77JC4(1990), L77JC4(1980), J4C(1970) from my parts list - but 2000 year model has 4 different plugs specified depending on the particular model - so do not assume the plugs in your engine now are the correct ones either - check carefully.
A set of new plugs in a waterproof container along with basic tools are essential for any two stroke.
Spark plugs can fail for a number of reasons, and sometimes only after a few hours use. Constant fouling indicates fuel mix problems, low compression, constant idling amongst other things.
If there is no change by swapping out the plugs you would check fuel, possible damage to ignition coils (hairline crack etc.) and if the plug caps are even on tight.
It's probably the plugs only.
Good luck.
