I recently purchased a boat with a 35hp johnson 3 cylinder engine J35VL3SIF.
The neighbor said it would need a CDI installed.
Bought a new CDI, installed, engine ran fine on muffs.
Maiden voyage on small lake, ran about 5 minutes and stopped.
Got it restarted, ran about 5 minutes and stopped.
Found that when I installed the new CDI, wires were against the block and melted together.
Returned the following day, installed old CDI, ran for 5 minutes then stopped.
No spark to any cylinder now.
Any suggestions would be appreciated.
 
Forgot to mention that temperature/choke sensor (2 wire) insulation on wires was damaged. Soldiered splice, and covered with insulator & friction tape.
 
Lets start with a compression test.----Post your numbers.-----Wires against the block should not melt.-----Remove the water pump impeller and post pictures of it.----
 
After further testing it was the stator.
The wires on the cdi box were pinched.
Put the new stator on and the old cdi, running like a charm.
Thanks for the input.
