See how to remove the cylinder heads head on your Yamaha F225 in this video from Boats.net.
This engine is in need of serious work, and in this video, John will show you how to teardown the powerhead on your F225. If you’re replacing the head gasket on your F225 or doing a complete powerhead rebuild on your Yamaha outboard, this will help you get things broken down.
We’ll start by removing the belt, and then we’ll remove the exhaust plates on our F225. Then we’ll work on removing the cylinder heads on our outboard. That’ll involve removing the valve covers, the camshafts, and then removing the heads. Then we’ll remove the tappets and valves, where we’ll get a closer look at what’s going on in this engine.
