????.. Valve shim clearance is guaranteed for life...???

The inline 6-cylinder Mercury Verado 225 HP is one of the few supercharged outboards on the market designed to provide robust low-end torque. That means the engine can produce snappy mid-range acceleration and plane at a lower speed. Its unique overhead cam design means that the valve train does not need maintenance for life.

LOL.. a whole bunch... why??

How to remove the lower unit on a Mercury outboard motor ...

Try adding a plane to the lower unit of the outboard motor.
SE Sport 200 Hydrofoil
This will plane out the boat quite well.

have the fault codes read and if it shows a problem in the exhaust area then it would be a fair bet it has affected the performance of the engine.

If it is 2-stroke engine check oil level and the oil level sensor.

If you know the year or model number, you should be able to find the diagrams at http://www.crowleymarine.com. Otherwise call, I've known them to be really helpful.
