Nissan 3.5 NS3.5 A flywheel

I have a Nissan 3.5 outboard it is a NS3.5 A. It has been a great little motor BUT suddenly I have no spark. Replaced the plug still no spark, check the continuity all seems good now to pull the flywheel, and get to the points, condenser and magneto. Here is the problem anyone ever pulled the fly wheel on this motor? The flywheel appears it is in a housing which is part of the motor so you cannot get under the flywheel with a puller as most motors. There is also not a couple of threaded holes on the flywheel to screw a couple e of bolts in to attach the puller to, some motors have such. I have never had a motor like that but am aware of such. If anyone has pulled a flywheel off a Nissan 3.5 motor I would like to hear from you. I hope it is something easy and I will feel stupid for not figuring it out myself.
 
You do use a puller. It does thread into the flywheel with 3 bolts. If your motor is so old that it has points, you will be hard pressed to find points and condenser.
 
Bring the flywheel nut up to the top of the threads of the crank shaft. Tap the nut, softly, with a hammer. Hopefully nothing at all happens. That's your starting point. Now tap it with slightly increasing force until the flywheel pops loose.
 
Yep, that works as well. Did you ohm-check the ignition coil? Points usually wear gradually, so unless the condenser took a dump, you may not even need to pop the flywheel.
 
NAPA has the cutest little flywheel puller should be a site for tool porn. Yes the problem is the coil. But pulling the flywheel needs to be done for my state of mind anyway. I understand this part is hard or nearly impossible to get. Is there a cross over part available? The coil is a Mitsubishi F6T405. Thanks
 
The coil is NLA (no longer available) from Tohatsu America. You may be able to cross over to something, or a dealer might have new old stock on a dusty back shelf.
 
This is an old thread but may benefit from some more input.

Pulling the flywheel is easy with a home-made tool. To make the tool, take the pull-starter off, then take off the yellow metal "cup" that is mounted on the flywheel after first marking which holes have the bolts in them. Cut a metal plate (reasonably substantial, please; I used 1/8" steel) to be somewhat larger than the largest diameter of the "cup". Position the "cup" in the middle of the plate and mark out the metal plate with the centres of the holes that had the bolts. Drill these holes with a 1/4" drill bit. These holes should form an equilateral triangle.

Now drill a fourth hole at the centre of the triangle, also 1/4". Put a 1/4-20 bolt through the hole and tighten a nut on it. With the plate oriented so that the 1/4-20 bolt in the centre of the triangle has its head against the end of the crankshaft, bolt the plate to the flywheel using the three bolts that originally held the metal "cup" to it. Don't use the lock-washers, however. Adjust the three bolts so that the plate is roughly parallel to the face of the flywheel.

Now tighten each bolt by a 1/4 turn. Repeat until the flywheel pops off.

Save the metal plate for future motor repairs.

Hope that this helps.

Why not? I was looking for a way to solve this and I found one. Why wouldn't there be someone else who could benefit from my idea?
