1988

I found a mixture of sites for the information one owner of a 1998 25 hp evinrude says that it is a 2 stroke with a fuel mix ratio of 50:1 as 25:1 is a bit smokey another site says that the recommended octane fuel rating is 87 although it might run better on 91 best advice is to find an evinrude service dealer and get the right information as the later 25 hp units are etec engine which will be 4 strokes

2 cycle, 50:1

known as maintenance !! they dont clean them selves and more you use them more times you need to check and clean them ! unless they have shorts or damaged wires etc these engines are simple and reliable ! if your getting lots of dirt under the flywheels then check the top crank seals not leaking as this will foul the contacts also !

Hi PaulCertainly you can. We use mid-grade or supreme in our Honda 15 outboard all the time. If the higher octane isn't needed, no harm done. After all, with a boat motor, it's working hard all the time and the higher octane certainly can't hurt.Hope this helps.-Steve

Remove the 4 spark plugs , number 1 is the top piston so put it to tdc then with a screw driver feel through each plug hole for which is the next piston to come up to tdc etc etc till you have written the order ! 1,2,4,3 or 1,3,4,2 !!

Have you replaced the impeller in the lower unit recently? If so was it in pieces? I would start there.
