First Winterization

[TomSearay350]

Took ownership of a 1991 Sundancer 350 last month and now I’m gathering information about winterizing. Lots of great information on this site. Let me summarize what I know so far for folks to comment on:

1. Engines

• Fill gas tanks, add stabilizer
• Run until warm, close fuel supply and fog engine (I use Marvel Mystery oil poured into carburetor).
• Change coolant
• Drain muffler canister? – how’s this done?
• Does heat exchanger get drained? How?
• Remove raw-water impeller
• Drain raw-water supply, hoses, strainers, heat exchanger? – how’s this done?
• Clean and lubricate as required
• Change oil
• Missing anything???

2. Water systems

• Drain water tank, faucets, head, etc. Blow-out?
• Pump-out waste tank
• Bypass water heater and drain – add any antifreezer?
• Add pink antifreeze to fresh water tank – how much?
• Run faucets (hot and cold) until solid pink
• Add additional antifreeze to head, flush – should antifreeze be added to waste holding tank?
• Ice maker – mine does not work, so I will disconnect hose from solenoid and drain until pink
• Missing anything?

3. A/C - Heat pump

• Blow-out through water outlet with compressor
• Pump in antifreeze
• Close seacock?
• Missing anything?

4. Missing anything?

Thanks,

Tom

OK, can someone point me to a comprehensive guide to winterizing a boat like mine?

Thanks,
