Hauling out is easy. Getting ready for winter is where most boaters cut corners. A quick reminder before you shrinkwrap: moisture and old fuel cause more winter damage than most people expect. Flush the cooling system, add fuel stabilizer, check the zinc anodes, and ensure your engine is protected from the inside out. Then wrap it tight and vent it right so condensation doesn't get trapped.

Your impeller is a small rubber part with a big job. It pulls cooling water through your engine, and that water is what keeps it from overheating. Over time, the vanes harden, crack, or break off, and the flow drops before you notice anything wrong. A worn impeller can leave your engine running hot, and that damage is far more expensive than the part itself.

That's why most boaters replace it once a season, and why it's smart to keep a spare on board. Find the right one for your engine at MarineEngineParts.com.

Heading out of the water soon? Before your boat goes into storage, take a few minutes to look at the steering system. It's easy to overlook, but it's one of the best things you can check before winter.

A quick look can tell you a lot. If the wheel feels stiff or loose, or the cable doesn't move as smoothly as it used to, that's worth a closer look now rather than next spring.

Engine Running Hot?

Before you panic, swipe through and check these three things. 9 times out of 10, an overheating engine comes down to one of these, and they're all fixable.

Here's what to check:

1️⃣ Water Intakes & Strainers — Weeds, mud, and debris blocking water flow is THE most common culprit. Look under your boat and inside your strainer basket.

2️⃣ Impeller Condition — Worn or cracked blades stop water circulation cold. If it looks rough, replace it.

3️⃣ Thermostat Status — A stuck thermostat stops cooling water from reaching your powerhead. Salt deposits and corrosion are the usual suspects.

Caught a problem? We've got impellers, thermostats, water pumps, zinc anodes, and every cooling system part in stock. Same-day shipping if you order today.
