Just posing this question would you recomend or not ?
 
Not worth the risk, in my opinion. Running out of fuel mid-stroke can damage an engine, especially on carbed engines. Maybe not likely, but why risk it. If the engine will be laid up long enough for that fuel to get gummy, then just run some Stabil.

If you have an F150 or an HPDI, drain the VST if you will be laying the boat up for more than a month or so. Draining will remove more fuel than running until the engine dies. Otherwise, just use a stabilizer.
 
VST is this the filter thats before the carbs ?
 
If you have a carbed engine, you won't have a vapor separator tank (VST). That's part of a fuel injection system.

You can drain the bowls of the individual carbs, but it is a PITA.

With a good stabilizer like marine StaBil, you will be fine without draining the carbs.
 
At my yard, we have had issues with gaskets drying out when the bowls were drained for storage. The next season the cardb would leak of course. So, we usually don't drain the bowls. We treat the gas or some guys pump Marvel Mystery oil into the bowls for winterization.
 
It is supposed to prevent corrosion and keep the gaskets from drying out.

Not necessary if you use StaBil.

Bob, as the name implies, it's a 'Mystery'

Actually, guys have been using the Mystery Oil for years (decades perhaps) and I don't know if it helps but for sure it doesn't hurt.
 
I had the same issue as Seasick mentioned...drained the bowls in November and sure enough. next Spring the carb bowls leaked.....they need to stay wet...just good prepping of the gas as Doc mentioned is needed.
