My fellow Monty sailors! My M-17 "Little Breeze" has a 4hp Yamaha OB that has a small internal tank holding only about a quart of fuel (45-50 minutes). I wish to add small 2-3 gallon external tank but so far have been unable to find a tank that will fit in the small starboard lazarrete which is only 11"x 14"x 10" deep. Any suggestions or experience out there...Thanks. Arnold Sharpe, M-17 "Little Breeze", sailing out of Portland Oregon on the Columbia River.
