I have about a 6 year old Evinrude 48 SPL that has a problem. It idles fine
and revs fine as long as it is not in gear but once you put it in gear
there is no power and it is hard to keep it running. I checked the foot for
gear lube and it seems fine. Put a water clamp on it and ran it in my
driveway and the prop turns freely. Rotated the prop by hand with the engine
off and it spins freely. Does anyone have any ideas?

Thanks for your input.

One cylinder is not firing.

Check your plugs and plug wires.

If it will run and rev out of the water, on the muffs, and then it has no power
IN THE WATER on the lake... your carb(s) need to be rebuilt.

Check the timing. Check for good, bright spark from the plug wires. Spark
that jumps a big gap. Lots of other things than carbs reduce power.

I vote for carbs. Having had several 45hp Johnsons for about 25 years, I'd
about bet on it. Bet it's been sitting for a while.

My first guess is low compression. Get a compression gauge and check.
Second would be carbs. Chances are it is not an ignition problem if it revs
fine in the drive and does not miss.

Thanks everyone for the replys! The plugs are the problem. One loose wire
and the other one fouled! Duhhhhhh.
I feel foolish. Once again, thanks everyone for the input.
