I use boats in Ontario & in Florida throughout the year. In Canada we fish even if temps are below zero and in Florida we fish in temperatures that are over 90F.
When I store boats for 1-3 months in-between usage I try and fill up the gas tank to prevent condensation and having water accumulate in the fuel but when I plan on using the boat again I always add K-100 Fuel Treatment to ensure that if there is any water in the fuel my engine will still be able to combust it. K-100 really makes “water burn” and keeps the flow going!!
