What size fuel tank does my older Key West Boat have?
Almost without exception, if your model is still in production you can check the current spec sheet on that model and find your tank’s capacity. The exception is in the 186 series where they were introduced in ’04 with a sixty gallon tank which was replaced with a forty gallon tank in ’06. Because of more efficient hull construction combined with fuel miserly engines, we found it simply did not need that much fuel. The out of production 1700CC carried a 17 gallon tank under the console, and the 1700DC had a 20 gallon tank under the floor.
