Fellow boaters,

I have been in the electrical construction industry for 15 years so I can do any type of electrical troubleshooting there is. The first two years I owned the boat it just worked! The only thing I did was change a bad lower unit and water pump guts. My dilemma is that in my plight to get my motor started this year, with some gracious members in another post, is that I am realizing that I really don?t have much in the way of mechanical tools and knowhow. Don?t get me wrong though, I have worked on cars and my last boat- it had a 4.3 with and Alpha One. I have the general sockets, drivers, open end wrenches etc.

I have a 1990 Force 120 L drive with the blue coils and would like to get it into top running conditions (after I get is started:(). I used a timing light some 20 yrs ago on a car that I owned and have seen friends use compression testers but don?t own any of these. Should I?

What are the tools I should have on hand for this motor? Can you all recommend any specialty tools specific to this motor like a stator tester or coil tester or possibly something that would tell me the strength of the spark? Any special tools for the fuel system?

A GOOD (mine cost $100)compression tester will always be a good thing in the tool box.A GOOD multi-meter(peak reading would be a plus).A plug wire removal tool.A screwdriver that's long enough to reach your air screw.A factory manual is good.
The L-drive is one of those units that is harder and harder to find parts and someone to work on them(I won't touch them).
They were only produced a couple of years and they figured they were not worth the trouble.Good luck with yours.J

Here is a tool that I made myself for testing the spark/spark plugs. I like this because it uses the actual plugs. If you have a bad plug, you have a pretty good chance of seeing it. Attach the cable to ground (the engine block) and you're good to go.

Ingenious, so you can actually see the plugs fire when they are on this tool? This is cool, maybe you should patent it.

I noticed that the coils on your motor are black and look a little different than mine, are these aftermarket?

Yes you can actually see the spark jump across the gap. I use a remote starter switch wired across the starter solenoid. Turn the ignition key to the "ON" position, attach the cable with the clamp to a bolt on the engine block. I can stand right next to the motor, press the remote starter button and watch.

Yes, these are replacement coils from CDI Marine Electronics. I have since upgraded to later model Mercury CDM ignition system.
