Replacing Waste, Water Systems
You can bring it to MarineMax or its expert technicians can come to you. One of the first things MarineMax does to begin the winterization process to your boat is flush its systems, including switching out the oil, oil filters, fuel filters and lower unit oil.
Using car antifreeze on your boat engine is a no-no. Yes, you want to flush your boat engine with antifreeze as part of boat winterization but only if it’s marine-grade. Automotive antifreeze can actually destroy both your cooling system and engine block. MarineMax technicians are adamant about making sure marine-grade antifreeze is used everywhere freshwater comes through the craft. Remember: If the pump still holds water inside, it can burst during the cold season.
Cleaning Insiude, Outside
From the time MarineMax technicians step onto your boat, cleanliness is top priority. They take special care when winterizing by tidying up sinks, counters and areas where they’ve worked on boat parts. You want to follow up this step by taking items like clothes and food out while your boat is sitting for a few months.
