I've had several people in Ontario suggest that salt water and aluminum boats do not mix. While in Nova Scotia I noticed a majority of flounder fishermen in alumium boats. Is there a problem? Can I dock my 22 foot aluminum boat in salt water for the summer season or should I trailer it and rinse after every use? I have the same questions about my 175 hp outboard motor. The unit is 25 years old but in mint condition. I would consider a new ETECH which is supposed to do well in salt, if it were necessary.
