Re: Johnson 48 hp SPL
I was given this outboard gentlemen told me it was running on one cylinder only. i'm gonna change plugs and check the coil or could it be something different. model number is VJ48ESLCCC serial# G7757001 not sure what year
first things first, check for spark to each plug, then check spark from the plug...if you have spark in both, check compression, if still running bad, rebuild the carbs...
you have a 1988
I have the same motor...they run rough....they seldom run smoooooth
especially on the rack on muffs
good luck
