Hello, I have a 2004 Johnson 175 2 stroke outboard that is on the boat I purchased last year. I rebuilt the carbs (float bowls, gaskets, etc), 2 new 24 series batteries, new NGK plugs to replace the old champions,plastic timing wheel on top (old one cracked pulling it off to replace bad starter, raw water pump, lower unit gear lube. All items were Johnson factory, no aftermarket junk. I was running it on the main fuel tank then switched over to a clean 6 gallon fuel tank.
I have a spark checker attached, and also tried cranking it with a few squirts of ether (I don't like using it but just wanted to see if any cylinder would hit). I had it running on the driveway last year after I bought and and did the above work to it and it did seem to cut out a few times on me.
All of the connections are clean, I have proper 12v and ground to the starter and engine block, trim works just fine, key switch cranks the engine just fine, key switch also operates the choke. When you turn the key on the dash gauges do come to life and the 4 red LEDS come on as well as the ignition beep.
The one thing I have noticed is someone ran and additional grey wire (tapped into the tach grey wire above the voltage regulator and run all the way up to the tach, the original grey wire was removed and left there). When I was running the boat in the driveway and boat ramp, the tach was working but I do remember it jumping around a bit. When I crank the engine now, the tach does not move.
The engine is clean and not all corroded (on a 1997 21' hardtop walk around fishing boat-saltwater use).
Thank you in advance!!
