Fuel additives for winter storage

[Glory]

Why would you start caring more about your, fuel, engine, injectors or any part more in the winter. You should take care of that stuff all year long.

In my case its to keep everything lubricated during winter layup. I have had two broken rocker levers from a stuck injector. Ive also had minor PT pump corrosion. My "hot mix" keeps everything loose for the five months that it is sitting.

Thinking of winterizing which I no longer do. Back when my dad had the 34 we left it in the water in NJ one year so we could use it for Cod in January. Some genius talked the old man into plugging the exhaust since being in the water all that damp air would travel up the exhaust and into the engines. Bad idea I guess it became a steam bath in there from the residual water in the exhaust and both engines had the valve trains frozen when we tried to turn them over in the spring.on a positive note it did push him into repowering with the Cats.

Hi putting my boat with Detroit’s in winter storage wondering what additives
are recommended all advice would be greatly appreciated

I've been using Biobor since 2013 with no problems, and I don't use a lot of fuel. One bottle easily does both tanks.

I bar my engine over in the spring just to make sure. Turning it over by hand will tell me if there are any issues. I have rebuilt both engines and don't need and more problems.

I can probably figure it out, but how do you bar the DD V's?

A 1-5/16” socket on a breaker bar and 3 or 4’ of pipe will do it.
