The #1 Mistake Perryville Boaters Make When Winterizing (And How It Costs Them Thousands)


As the vibrant Missouri summer gives way to the crisp autumn air, boat owners in Perryville and the surrounding Perry County are faced with the annual ritual of winterizing their vessels. For many, this process is a race against the first freeze, a series of checks and balances to protect their prized investment from the harsh realities of a humid continental climate. While most boaters are diligent, there's one critical mistake that we at Perryville Mini Storage see time and time again, a costly oversight that can lead to thousands of dollars in repairs: improperly winterizing the engine's cooling system.


The Heart of the Matter: Your Boat’s Engine

Your boat's engine is its heart, a complex piece of machinery that powers your adventures on the water, be it a fishing trip on the Perry County Community Lake or a leisurely cruise. However, that same engine can become your biggest liability when winter arrives in the 63775. The number one mistake we see is boat owners failing to properly drain all the water from the engine block and replace it with a quality marine-grade antifreeze.

It’s an easy mistake to make. A simple oversight. Perhaps you think you've drained enough water, or maybe you underestimate the severity of a Perryville winter, which on average brings 11 inches of snow. But here’s the hard truth: any water left in your engine block will freeze. And when water freezes, it expands by about 9%. This expansion exerts immense pressure on the cast iron or aluminum of your engine block, leading to cracks that can be catastrophic.


A Costly Mistake: The Price of a Cracked Block

A cracked engine block isn't a minor repair. In most cases, it requires a complete engine replacement. The cost of a new marine engine, coupled with the labor to install it, can easily run into the thousands, if not tens of thousands of dollars. Suddenly, that beautiful boat that brought you so much joy becomes a source of significant financial stress. This is a devastating blow that can cut your next boating season short before it even begins.

Beyond the financial cost, consider the lost time and frustration. While your friends are enjoying the first warm days of spring on the water, your boat will be stuck in a repair shop. The memories you planned to make, the family outings, the peaceful moments of solitude – all put on hold because of a preventable mistake.


The Solution: A Proactive Approach to Winterization

The good news is that this costly mistake is entirely avoidable. The key is a thorough and meticulous winterization process. Here’s how you can protect your boat and your wallet:


Read Your Manual: Every boat and engine is different. Your owner's manual is the best resource for specific winterization instructions.

Drain Completely: Ensure every drop of water is drained from the engine block, manifolds, and hoses. Don't rush this step. 

Use the Right Antifreeze: Not all antifreeze is created equal. Use a non-toxic propylene glycol antifreeze specifically designed for marine engines. A 50/50 mix with water is typically recommended to provide protection against freezing and corrosion. 

Stabilize Your Fuel: Fill your fuel tank to about 90% capacity and add a marine fuel stabilizer. This prevents condensation and keeps your fuel fresh. 

Change the Oil: Old oil contains contaminants that can damage your engine over the winter. Change the oil and filter before storage. 

Protect from the Elements: A proper cover is essential. While shrink-wrapping is a great option, a high-quality, custom-fit cover will also do the job.
