Mercury Tracker 40 Powerhead Teardown | Mercury 40HP 2-Stroke Powerhead Disassembly | Boats.net

See how to tear down the powerhead on your Mercury Tracker 40 2-stroke in this video from Boats.net. This motor was basically seized up when we got it, and a look with the borescope showed some real damage in one of the cylinders. In this video, we’re going to disassemble the powerhead on our Mercury Tracker 40 2-stroke to see what can be saved and what needs to be trashed. We’ll work out way around the engine first: removing the intake and carburetor, and then removing the electronics on our Tracker 40. Then, we’ll use a flywheel puller to address the flywheel, and after that we’ll crack the engine open. And oh boy, wait ‘til you see that piston.
