2001 mercury 125hp 2 stroke

[Ed Harris]

Trying to get a mercury 125 hp 2 stroke running. 100 psi on all 4 cylinders but no spark on any of them. Where do I start looking?

 

[Ed Harris]

What size fuse is his fuse supposed to be? and
The two yellow wires coming from the stator connect to the two yellow wires on the rectifier correct?

Yellow wires are battery charging....completely separate circuit. You want the other wires Green/White stripe and White/Green stripe are your CDI storage capacitor operating voltage and the other bundle with purple, black brown, blue, and white are your triggers and dc supply.

The service manual for all engines in your series and year-models states that any compression readings below 125 one should expect problems!

Sorry for the typo I just caught it.... it’s a 2000 saltwater series but that shouldn’t matter much.... should it?..... do you happen to know what size fuse goes here
They had a 3A in it and it was blown but that seemed kind of small to me anyway.

Do a www search for pumps and find one or several like yours and look up the power or amperage spec. Fuse for 2x with a fast blow fuse.
