Mariner 80hp 1983

Hi

Anyone know how to remove this disc so I can get to my trigger? Not sure if there is a nut holding it down. I have a washer in the shaft that won't come off or should I tap it off?

There is usually a nut in the center of the inner flywheel. Once that is removed, Mercury uses a standard fitting that screws into the large threads around the but, and a bolt thru the fitting. Tighten the bolt and hold the fitting ith a wrench, and the inner flywheel will pop off.

The flexplate should not be taken off.----Flywheel is removed as 1 unit.------Use the factory style puller ( I made one years ago.) ----Or use a puller and 2 threaded holes bolts of the 8 to do this simple job.

When you reinstall flexplate, make sure it is in the correct position, or it will screw up your ignition. It is easy to do, simply set the #1 piston to TDC, using a screwdriver thru the plug hole. Turn the flexplate until the decals indicate TDC, line up the nearest hole and install the bolts with some blue locktight on them.

We marked the timing before taking it off.

Thank u for your advices. Will pu the plate back on and use a pully to take it off
