Winterization
Boat Winterization
Water expands when it freezes, and there is no part of an engine built to survive that. Winterizing gets the water out, protects what stays behind, and turns the most expensive mistake in boating into a routine afternoon. Our technicians winterize boats and personal watercraft of any make, whether you store with us or take it home.
What We Winterize
Every System That Holds Water
Winterizing is not one job, it is a checklist across every system on the boat that holds water, fuel, or a charge. Miss one line and you can still crack something over a cold night in February, which is why we work through all of them rather than the obvious ones.
Engines And Cooling
The block, manifolds, and cooling passages drained and protected, since this is where freeze damage does the most expensive harm.
Outdrives And Lower Units
Gear oil changed and checked, which also tells us whether a seal has been letting water in without you knowing it.
Fuel Systems
Fuel stabilized and filters addressed, so ethanol does not separate and leave you with varnish and a boat that will not start in spring.
Freshwater And Livewells
Livewells, washdowns, pumps, and plumbing cleared, because the small lines are the ones most often forgotten and most easily split.
Batteries And Electrical
Batteries disconnected and handled properly, so you are not buying a new set every spring because they sat flat all winter.
Interior And Canvas
Bilges cleared, cushions and canvas dealt with, and everything left dry and vented so mildew does not take hold over the winter.
How We Do It
What Winterizing Involves
Every engine is slightly different, and what is correct for a Mercury outboard is not what a MerCruiser sterndrive needs. The order below is the shape of the job, and the specifics follow whatever your engine manufacturer calls for.
Water Out And Antifreeze In
The cooling system is drained at every point it holds water, which on many engines is more places than owners expect. Where the design calls for it we then circulate marine antifreeze so anything that cannot be fully drained is protected rather than left to chance. This single step prevents the cracked blocks and split manifolds that account for most winter damage bills.
Fogging The Engine Internals
With the water dealt with, the inside of the engine still needs protecting from months of sitting still. Fogging coats the cylinders and internal surfaces so they do not corrode while the boat is idle, and oil and filter changes go in at the same time so used oil is not left sitting in the engine all winter.
Fuel Stabilizing And Filters
Modern fuel does not age well. Left untreated over a winter, ethanol blends can separate and leave water and varnish in the tank and lines, which is why so many boats crank without starting on the first warm weekend. Stabilizing the fuel and dealing with filters and water separators avoids that entirely.
Lower Unit And Final Checks
Changing the gear oil is also the best diagnostic on the boat. Milky oil means water has been getting past a seal, and finding that in October means it is fixed over the winter rather than discovered as a much larger repair in June. We finish by checking the bilge, batteries, and anything else holding water.
Why We Stand Out
What Sets Our Winterizing Apart
Winterizing is cheap insurance done properly and an expensive false economy done badly. The difference is whether the person doing it knows your particular engine and actually checks every point that holds water.

Our Process
Our Winterization Process
Five stages, usually inside a single visit, and you leave knowing the boat is protected until spring.
Book It In
Call before the first hard freeze, since the last weeks of fall book up fast.
Drain
Every point holding water is drained and antifreeze added where needed.
Protect
Fogging, oil and filters, fuel stabilizer, and gear oil all go in.
Inspect
We flag anything we find so it can be fixed over the winter, not in June.
Store Or Collect
Leave it with us for indoor winter storage or take it home protected.
Frequently Asked Questions
Answers To Common Winterizing Questions
What does winterizing actually include?
Draining the cooling system and adding marine antifreeze where the engine design calls for it, fogging the internals, changing engine oil and filters, changing and checking lower unit gear oil, stabilizing the fuel and dealing with filters and water separators, clearing freshwater and livewell plumbing, and handling the batteries. The exact list follows what your engine manufacturer specifies.
When should I have my boat winterized?
Once you are finished using it for the season and before the first hard freeze. In this part of Pennsylvania that usually means booking through fall rather than waiting for the cold to arrive. One unexpected freezing night is all it takes, and the last few weeks before winter are always our busiest for this work.
What happens if I skip it?
Water left in a block, manifold, or line expands as it freezes and cracks whatever is holding it. The damage is usually invisible until the first launch of the season, and by then you are often looking at a rebuild or a repower rather than a repair. It is comfortably the most expensive avoidable mistake in boat ownership.
Do I still need it if the boat is stored indoors?
Yes. Indoor storage protects the boat from snow, ice, and sun, but an unheated building still drops below freezing on a cold night, and the water sitting inside your engine does not care that there is a roof above it. Storing indoors and winterizing solve two different problems, and you want both.
How long does winterization take?
Most boats are a single visit job. Larger boats, twin engines, or anything with extra plumbing take longer. If we find something that needs attention while we are in there, we will tell you before doing any additional work.
Do I have to store with you to get it winterized?
No. Winterization is a standalone service. Plenty of owners have us winterize the boat and then take it home for the winter. If you would rather leave it here, our indoor winter storage is available and the two are easily booked together.
Do you winterize boats you did not sell?
Yes. We winterize virtually any make and model regardless of where it was bought. Our technicians work on Mercury, MerCruiser, Volvo Penta, Evinrude, and Johnson, along with brands we do not sell new such as Yamaha.
Do you winterize personal watercraft?
Yes, and they are more vulnerable than most people assume. A jet ski packs a lot of cooling and plumbing into a small hull, so there are plenty of places for water to sit and freeze. They are quick to do and cheap insurance against an expensive spring.
Can I just winterize it myself?
Some owners do, and on a simple outboard it is manageable if you follow the manufacturer procedure exactly. What catches people out is the places water hides, since many engines have drain points that are easy to miss, and a single trapped pocket is enough to crack a housing. If you are not completely certain you have got all of them, the cost of having it done is a fraction of the repair.
Will you tell me if you find a problem?
Always, and this is one of the quiet benefits of the job. Changing gear oil shows up water intrusion past a seal, and general access shows up worn impellers, tired hoses, and corrosion. Finding those in the fall means they get fixed over the winter instead of ending a summer weekend.
How much does winterization cost?
It depends on the engine, the number of engines, and what else the boat has holding water. Call us with the make and model and we will give you a straight price rather than a range that would be wrong for most boats.
Do you shrink wrap boats?
If your boat is going home or staying outside, talk to us about covering it, since a good fitted cover matters over a winter and our shop makes and fits canvas. If it is coming into our indoor storage, wrapping is not needed at all, which is one of the savings of keeping it inside.
What about getting it going again in spring?
De winterizing is the other half of the job. Antifreeze is flushed, the battery goes back in, fluids and belts are checked, and the engine is run and tested before you take it out. Book it early, because the first warm weekend of the year sends everyone to the phone at once.
How do I book winterization?
Call our service department at 814-658-3464 or use the button on this page. Tell us the boat and engine and whether you want winter storage as well, and we will get you a slot before the cold arrives.
Ready When You Are
Book It In Before The Freeze
An afternoon in the fall costs a fraction of an engine rebuild in the spring, and fall slots fill quickly once the weather turns.
