Hey all,
I’ve got a 2001 25HP
Model 25EL
Serial 0T310530 (I included the serial because I can’tfigure out how to distinguish between the 3 different 25EL’s listed inboats.net when looking for parts)
Anyhow, I went from firing right up to a couple weeks laterhaving no spark.
Let me try to preemptively answer as many of the questionsany of you might throw at me. As well asjust listing as much info that may be useful.
So I’m open to suggestions and even some smart ass commentslol.

- Theboat is stored on a dry dock but is sitting on brackish/salt water. Socorrosion is always a battle.
- Iam educated and employed in the field of electrical and electronics testingetc. But finding correct data on acceptable resistance or voltage drop oncomponents on this motor seems to be few and far between.
- Ihave checked and repaired or replaced all visible connections from theswitchbox to the starter solenoid, starter, rectifier, coils, kill switch, etc.
- Ihave tested both the kill switch and the neutral safety switch. As well aschecked for spark after bypassing them and manually defeating them.
- BecauseI could not get much info, I purchased a new switchbox in hopes of itcorrecting the issue, but still had no spark.
- Andyes…… just to make sure I wasn’t shooting myself in the foot, I swapped thespark plugs themselves lol.
- I’mnot sure what kind of values I should see when testing the stator, trigger andcoils. So any help on those would be greatly appreciated. Also if anyone has awiring schematic on this motor, that would be helpful.
So I’m open to suggestions and even some smart ass commentslol.
