Hey all...
I have a 77 55hp Evinrude on a 16ft '75 Ranger. I just bought it, knew it needed work, and dove in.. lol...
Replaced new are:
Carb kits (increased jet size in idle circuit)
Fuel Pump / Filter
Power Pack
Coils
Rectifier
Fuel Lines (ALL) w/ bulb
Fuel Tanks
Batteries
Light wiring
Here's the problem.... The engine will run fine for a short time..(5 to 20 min), then stall so suddenly, it is as though you just turned off the key. With timing light connected, I see no spark while cranking...After anywhere from 20 min to 1 hour, it will restart and repeat the same process.....
When it does run, it runs very well....
I think I have lost more hair with this boat than the two teenagers have caused...lol
But just recently, (yesterday) It ran for about 30 min (NEW RECORD) woohoo!!, Then wouldn't shut off (had to ground the kill switch wire to kill it)..It did this twice yesterday, and did NOT stall either of these times (each run was about the same distance).
Is it likely for the ignition switch to be causing such a stalling problem?..
I have a new one that I will be installing today, just wondering if anyone out there might help me with this...Is there anything else likely to cause this that I have not replaced?..(timer assembly)...I have NOT had the flywheel off yet.
As this is my first outboard to work on, I am at a loss...
Auto mechanic for 10+ years....(but I am beginning to understand, that means NOTHING) lmao.
