What type of motor is it - fuel injected or carburetor?

When you say the motor will not shut off or the shut off switch doesn't work - how long does the motor stay on? - seconds? minutes?

Does it run extremely roughly when it is trying to shut down?

So how do you shut down if it keeps running?

 

If it is a carburetor motor - it sounds like an issue of very bad timing adjustment

When was the last time the motor was serviced?

 

It has a carb. The engine runs great/smooth. Has lots of power. Starts quickly. Only every now and then it will not shut off. When it does happen, the kill switch also doesn't work and so I turn the key slightly like if I wanted to start. Then I can go back to off position with the key and the engine shuts off.

So far I've only replaced the ignition.

After engine is warm, occasionally the engine will not shut off. Also, the engine shut off switch does not work.

Any ideas why this is happening some times?

[Fresh Water Tank]

Just brought a used 2001 220 Explorer sport. Boat is in great condition, but did not come with any owner manuals. Can anyone tell me where the fresh water tank would be located?
