Fuel/Water separation filters
I've been doing a few winter jobs on my boat and trailer including winterising the engine, a Mercury 90hp (4). Do I needto replace the separation filter every season? I had a new one fitted last spring and probably did no more than 25 hrs at sea all summer, due to the sh1t weather we had. I have dosed the remaining fuel in the tank with Startron to prevent the petrol going stale so i am thinking there may not be any need to change the filter?
