Reply To: Power Head removal 1972 Merc 110 9.8hp

Bill is spot on. The powerhead adapter is the block that the powerhead is attached to, and the studs from the powerhead go through this to the drive shaft housing. The adapter is also held to the drive shaft housing by a single bolt below the spark plug. The lower pan is attached to the adapter by three rubber mounts, (These often are broken and are expensive to replace.) I have repaired them by welding studs to the bottom of these mounts and adding a rubber bushing.
The only thing you want to be aware of is if you don’t plan to remove the adapter, then be careful to not disturb the gasket between the adapter and the drive shaft housing. Also pay special attention to the plastic spacer on the water tube under the powerhead. I have found many of these that have melted and have severely restricted the water flow into the motor.
