Freezing water expands, which can easily crack an engine block or ruin a manifold. As part of our Boat Winterization (I/O & Stern Drive) Service Vancouver, our team meticulously drains the entire cooling system of your Mercruiser, Volvo Penta, or OMC stern drive. We clear all water jackets, manifolds, and hoses, then flush the system with premium, non-toxic marine antifreeze to guarantee complete freeze protection throughout the coldest months.

Stern Drive Gear Lube & Oil Change | Boat Winterization (I/O & Stern Drive) Service Vancouver
Water trapped in your outdrive gear casing will freeze, expand, and shatter expensive internal components. As part of our Boat Winterization (I/O & Stern Drive) Service Vancouver, we drain your outdrive gear lube to inspect for water intrusion, contamination, or metal shavings that may indicate developing issues. We then refill it with high-performance marine gear lubricant and change the engine oil and filter, ensuring your stern drive is protected against corrosion and dry starts come spring. Our comprehensive Boat Winterization (I/O & Stern Drive) Service Vancouver helps safeguard critical drivetrain components, extend equipment life, and keep your vessel ready for the next boating season.
Fuel System Stabilization & Treatment | Boat Winterization (I/O & Stern Drive) Service Vancouver
Leaving untreated fuel in your boat for months leads to phase separation, gum deposits, and fuel line degradation—especially with modern ethanol blends. As part of our Boat Winterization (I/O & Stern Drive) Service Vancouver, Aokboats treats your entire fuel system with commercial-grade stabilizers. We run the engine to ensure the treated fuel circulates completely through the fuel lines, injectors, or carburetors, preventing varnish buildup and fuel system contamination. Our professional Boat Winterization (I/O & Stern Drive) Service Vancouver helps protect critical fuel components, maintain engine performance, and ensure a smooth, reliable first start when boating season returns.
Fogging Internal Engine Components | Boat Winterization (I/O & Stern Drive) Service Vancouver
When a boat sits idle in humid winter air, condensation forms inside the engine cylinders, leading to destructive rust and surface pitting. As part of our Boat Winterization (I/O & Stern Drive) Service Vancouver, we apply a specialized marine fogging oil directly into the engine's air intake or cylinders. This coats the valves, cylinder walls, and pistons with a durable protective barrier that locks out moisture and prevents internal corrosion during long-term storage. Our professional Boat Winterization (I/O & Stern Drive) Service Vancouver helps preserve critical engine components, extend engine life, and ensure smoother, more reliable performance when boating season returns.
Battery Care, Terminal Protection & Diagnostics | Boat Winterization (I/O & Stern Drive) Service Vancouver
Freezing temperatures can completely kill a sitting marine battery, leading to premature failure. As part of our Boat Winterization (I/O & Stern Drive) Service Vancouver, we disconnect your boat's batteries, thoroughly clean the terminals to eliminate acid corrosion, and apply a protective dielectric grease. We also load-test the battery to assess its overall health, advising you on whether it should be maintained on a trickle charger or replaced before the next boating season. Our comprehensive Boat Winterization (I/O & Stern Drive) Service Vancouver helps protect your electrical system, improve battery longevity, and ensure reliable starting performance when it's time to get back on the water.

Our custom-fit covers create a tight, weatherproof shield that sheds snow, ice, and debris, complete with support structures to prevent sagging and mildew-resistant vents to ensure proper airflow underneath the wrap.
