That should be the correct one BUT ...... I have been fooled before. The best thing to do is remove the old one so you can measure the thickness of the ring gear and the diameter of the step on the flywheel where it sits. Pioneer shows 3 different 168 tooth GM ring gears. They vary in thickness and inside diameter. If you can measure yours and post the numbers here I can let you know which one you need. I have sold 5 of the FRG168S in the last few years and they have all been to marine customers. I have never sold one of the other numbers.

Awesome will do!! hoping to get the motor pulled the rest of the way down this Saturday so I'll get it off and do some measuring

I just did one of mine recently. You can warm up the ring gear itself with a propane torch for a few minutes (focus heat on ring gear not flywheel) and tap it off. Clean up the flywheel with a little steel wool, bake the new one in the oven at 350 for 10 minutes, drop it right on making sure it's evenly seated and then just let cool on its own. As mentioned above make sure you put the bevel side in.

Yup that's the plan...haven't had time to mess with it been working like crazy lately...hopefully it goes as easy as everyone described!!

It will, just take your time. Also, it's best to set flywheel up on a pair of blocks to work on.
