Hello
I?m having running issues with my 120hp 2002 Johnson w/ about 40 hours on it.
The motor has not been fiddled with, only things changed were normal routine maintenance parts.. Spark plugs, water pump, filter, etc.
Okay, this is a little history of what happened.
The motor was running completely fine up until last week.
Until I took the boat out into rough seas for a few hours. The motor started to run real rough and had loss of power, so I pulled of the bonnet to find the two left side plug wires hanging off.
Assuming this was the issue I put the wires back onto the correct plugs to find the motor still running just as rough as when they were off.
I just figured that I had fouled the plugs from loading up the cylinders. So I drove the boat home (about an hour)
When I put new plugs in at home the motor runs a little better but not even close to what it used to.
The idle is extremely rough and the boat shakes until about 2500 Rpm then it clears out and runs smooth.
I?m getting spark at all cylinders
Compression is perfect on all cylinders
I pulled all the plugs out again after putting another 3 hours on motor and all looked exactly the same.
Any advice or help would be greatly appreciated
Thanks in advance... Rich
