I have a 99 evinrude 225xi w/ intermittent shift problem.
Very hard shifting from F to N and to R.

A couple of times managed to get it into N and
RPMs went high (~2000rpm). One time
engine code light was set; but then went off.

I turn off boat and restart later and
NO PROBLEM! works great can't get it to repeat.
Hours later, problem returns. Very hard shifting
can't find N. Have to force it from F to R

If the problem would persist, I am sure I can find it
but when it works well most of the time, it is
hard to diagnose.



It does sound like a sticking interputer switch or stiff bushings in the
engine linkage. Any time a CHECK ENGINE lite comes on, an error code is
saved inside the motor's computer. It is accessable with a laptop or PDA and
the appropriate software and interface cable. See a knowledgeable tech.

The interupter switch only works when shifting out of gear into neutral, and
only when in the water with a propeller on the engine, it will not operate
when the motor is running on the flusher.

Remove the control cable and move the motor shift linkage by hand while
turning the prop to line things up. It should shift freely with 2 fingers on
the shift lever mounting stud. If not, remove the gearcase shift rod screw
and try again. If it is now smooth, then the shift rod most likely is
binding inside the gearcase cover where the oring seals it.

The switch should move freely inside its holder. Look for any burrs or nicks
in either the plastic or the metal that could restrict movement.

Make sure the boat's shift cable is adjusted correctly with an even "throw"
between forward and reverse. If the problem developed soon after any
gearcase or water pump work, perhaps the shfit rod height adjustment is
incorrect.

If you do it yourself, make sure you follow the factory service manual step
by step.
