Minor Engine Issues

[Blackened]

G'day

Just been out for a run today, all of 53km for 11L of fuel at full noise with 3 pob.

Now, here's the issue, Engine is a Merc (US) 2000 model 9.9 2 banger.

Never ever misses a beat, but today after the big run I have tried to start her at home for a flush but nothing.

Pulled both spark plugs, top is clean like the day it was put in, the lower one is just the same with a slight bit of oil/gum on it. I had both plugs positioned near the block with the engine being pulled over and no spark was evident, nothing at all.

Any chance it could be the "switch box" the black box with all wires coming out of it at the rear port side of the engine?

Reason I think it may be this, is same symptoms were had when this happened last time, but fixed under warranty

dave, does it try to fire at all?

[cormorant]

Dead mans lanyard kill switch is where I'd be looking.

Honda, no fire, hence why I pulled the plugs.

Cormorant, checked that, all good

Personally i never use a plug to test the spark.
I just grab the lead and crank the motor over;D :P . Seriously though i use a phillips head screw driver. Why a phillips head? If you get the right size it will fit perfectly inside th lead end.

I put the screw driver roughly 5mm from a good earth on the head. Then with the plugs out of the motor i pull like mad trying to keep the motor still.

This way will tell you if you have spark for sure.;)

Just an update

Took the boat in for a check as I tried to run the engine but to no avail. One half arsed attempt at it firing and then nothing, nothing and more nothing.

It was due for the 12mth service as it was, and ended up the issue being the CDI pack (switch box, mongrel black thing with wires )

A BIG thankyou to Anthony from Marine Worx up on redland bay road at the back of capalaba. Comes highly recommended by myself and others for a good job fair price and good communication.

His number is 0422330846.
