I am considering a 22ft Osprey for use in saltwater. I contacted Manitou concerning what I would need to do to make this pontoon saltwater ready and was told the following:

Seal the bottom keel, weld along both edges and cap off the end

Install second transducer bracket and mount sacrificial anodes on both

Have the bottom of the boat and tubes covered with a salt water specific hull paint

This will be my first boat and I need help putting this in simple terms that I can understand. Should I pass up this boat and keep looking?

You woudlneed to do that to any pontoon you bought not just that brand.

Sealing the keel is to keep barnacles and other critters from living in the keel, you need an anode on both tubes to keep from having problems with electrolosis and the bottom paint keeps critters from growing on the tubes.

Is this necessary if the boat will be taken out of the water each day?

I sure would. You may not have the barnacle issue but you'll still be battling corrosion.

Electrolysis is a nasty thing. Not only will a galvanic reaction occur between 2 or more dissimilar metals, it will be manifested by salt water (an electrolyte) . You should also note that electrolysis will occur from even the slightest current transferred through your motor or outdrive by merely leaving your battery connected or motor running. It most oftentimes is slight, but it does occur in addition to the charge and interaction created by 2 dissimilar metals. Metals take on a life of their own and how they react, or sacrifice one to another, depends on where they are on the Noble scale. So, make sure always that your sacrificial anode is in good shape.
