How to Use This Calculator

Enter Boat length (ft), Engine type (0=outboard, 1=I/O, 2=inboard gas, 3=diesel), and Number of engines.
Set Generator (0=no, 1=yes), Air conditioning (0=no, 1=yes), and Marine head (0=no, 1=yes).
Adjust Shrink wrap (0=no, 1=yes) as needed.
Review the Total winterization cost ($) result.
Use Engine winterization ($) and Water & plumbing systems ($) to inform your decision.

How the result changes with Boat length (ft)

Boat length (ft): Overall length of the vessel.
Engine type (0=outboard, 1=I/O, 2=inboard gas, 3=diesel): Propulsion type. Diesel and inboard engines cost more to winterize.
Number of engines: Total engines to winterize. Twin engines double the engine service cost.
Generator (0=no, 1=yes): Onboard genset requiring separate winterization.
Air conditioning (0=no, 1=yes): Marine AC system with raw-water cooling to drain.
Marine head (0=no, 1=yes): Marine toilet and holding tank system to antifreeze.
Shrink wrap (0=no, 1=yes): Protective shrink wrap cover for winter storage.

Total winterization cost: All-in cost including labor, materials, and shrink wrap.
Engine winterization: Fogging, flushing, oil change, and cooling system service per engine.
Water & plumbing systems: Fresh water drain, head antifreeze, and holding tank service.
Shrink wrap: Material and labor for protective shrink wrapping.
Generator & AC service: Winterization of generator and air conditioning systems.
Materials & supplies: Antifreeze, oil, filters, fuel stabilizer, and consumables.

Identify Input Parameters
4 parameters
Boat length (ft) = 24, Engine type (0=outboard, 1=I/O, 2=inboard gas, 3=diesel) = 1, Number of engines = 1, Generator (0=no, 1=yes) = 0 = 7 input(s) provided
Calculate Total winterization cost
Total winterization cost = laborSubtotal + materialsEstimate + shrinkWrapCost + storagePrepCost
1128.75 = $1,128.75
Calculate Engine winterization
Engine winterization = engineCostEach * numEngines
225 = $225
Calculate Water & plumbing systems
Water & plumbing systems = round((freshWater + headCost) * 100) / 100
244 = $244
