Hey guys! I've been away for awhile working on my new boat and truck. Im almost finished with my boat and I started on the motor. Well I cleaned the carb and tried to fire it up, it turned over great, good compression but wouldnt crank. So i started going over everything and discovered i had no spark. I pulled the flywheel and cleaned up everything. Still nothing so I'm am stuck, i dont want to just start replacing everything until i find the problem so if i could narrow it down with yalls help i would greatly appriciate it.

Get the Suzuki OEM shop manual, a volt/ohm meter and follow the instructions.
That's the best answer you are going to get, especially if you plan on keeping that antique.
40 hp pushing 1200 lbs of load (boat, engine, gear, passengers, fuel) will go fast enough
to pound your kidneys to a pulp running in a chop.

:cool:

My 25 yammie had a cylinder with no spark after checking everything I could think of I started stretching the wires and it turned out one of the connectors was bad. I hope your fix is as easy

That's why I recommend a volt/ohm meter. Works great for checking circuit continuity.
Also checks the resistance in a wire, alerting you to hidden corrosion before it becomes a major problem.

I started messing with the motor again today and i checked the fuse and it was fine. so i tried to turn it over again and checked spark... Nothing... so i pulled the ignition coil to check for a part number or something and the only thing on it was " mitsubishi electric 6510" i tried googling it and nothing so i dont even know how much to expect the repair to be. I would like to have a newer 40 but money is a major factor. If anyone wants to trade my suzuki a 1999 mercury 25 long shaft and maybe a little cash for a newer 40hp id be the happiest person in the world and i might even name the boat after you. haha

You already checked so it doesn't matter, but if the fuse was bad it wouldn't turn over, not turn over and no spark.

Disconnect the main wiring harness plug and use a remote starter, to see if the key switch is bad, Wait is this a remote or tiller?

Does this motor have 1 coil or 2?

Nope, you spend money on the proper tools (volt/ohm meter)
and get the Suzuki factory shop manual for your specific outboard.
In it you'll find complete instructions, pictures, step by step
walking you through the entire process. You can't do the job right
without the proper information at your fingertips.

Not Seloc, not Chilton, not Clymers....get the Suzuki factory manual!

or you can try looking in here...
