What should you do immediately if a boat motor catches fire?

 If a boat motor catches fire, you should immediately shut off the fuel supply, and try to put out the fire with an extinguisher. It is very important to have fully charged fire extinguishers on hand. As soon as you notice the fire activate the extinguisher and do not panic. In order to prevent fire remember to clean the bilges often and maintain proper gear stowage, make sure short-tie cables are properly connected...

I'm not sure what your asking buddy.. but i know that you can weld two peices of steel by pure force and pressure.
