We have 4460 with dual Mercruiser 8.1l inboards. I am wondering if it’s good practice to turn off the engine batteries and fuel source when we leave the boat for a couple of weeks and close the engine and generator seacocks

We have 4460 with dual Mercruiser 8.1l inboards. I am wondering if it’s good practice to turn off the engine batteries and fuel source when we leave the boat for a couple of weeks and close the engine and generator seacocks Couldn't' hurt. Having said that I always turn off my engine starting batteries when leaving the boat and just leave my house battery on. Boat stays plugged into shore power with battery charger on. Never thought about closing the gen/ac seacocks but couldn't hurt. Those should be exercised every once in awhile anyway. I don't have engine seacocks as I have outboards. On my boat if something starts leaking and my bilge pump runs or cycle, I get a text to my phone and then I can call someone onsite or run down to the marina. Great piece of mind ( siren marin boat monitor) Rob |

I have an '07 4460 and don't do any of what you ask about. I just plug into shore power, batter charger is on, and I leave the boat; all battery switches on, seacocks open. I agree with rlazar that it can't hurt to turn them off but I guess it's up to you. I do worry that opening and closing the seacocks too frequently can cause additional problems, but as rlazar alludes, it might also be an advance warning of an issue.

I think, especially if you aren’t using the boat to leave the batteries on and charger charging them. I pretty much turned off everything else on my 4460 and my 33 now when leaving the boat. I never turned the fuel off on my 4450, but it was a diesel.
