I don't see any spark at the plugs.

The spark plug cap on a Yamaha outboard consists of a wire spring inside a
rubber boot that pushes over the sparkplug cap, instead of a proper metal
cap. The wire spring shoves it way back up into the cap because nothing
holds it in place. The other end of the wire spring is simply shoved into
the center of the sparkplug wire with nothing really holding it but the
rubber cap. When this comes loose, of course, (not if), there will be no
or very low spark at that plug and the Yamaha will run like crap.

Unplug the rubber cap from the sparkplug.

Use needlenosed pliers to pull the metal spring back into the hole where
teh spark plug cap fits. Make sure the upper end of the spring wire is
still shoved up into the plug wire so it will get the HV pulse and
CAREFULLY wiggle it down over the spark plug cap until it seats. If you're
careful, you can feel the cheapass spring stretch over the cap...

It's crap...It's YAMAHA!

Larry,

Quite often your posts are very insightful, but sometimes they reek of
personal bias which often isn't born out by other's experience. This
is such a post.

I don't know which Yamahas you've looked at, but mine has a "proper"
metal cap. The problem is with the stator as the coil is an open
circuit.

Re the "It's crap...It's YAMAHA!" I would very much disagree. I've
owned 15 HP Yamaha 2 stroke motors for 5 years and have had ZERO
problems until now. The motor has started one the 1st pull and hauls
two people with dive gear on a plane with no issues. You can find
parts for Yamahas everywhere in the Caribbean, which is not the case
for other vendors. I used to own a Nissan 9.9 and it was next to
impossible to get parts for it. Honda and Mercury are rarely seen
down there other than when owned by cruisers. They may be good
motors, but just pray that you don't need parts.
