Hey fellow boat enthusiasts! Today, we tackled an intriguing challenge at Water Sports Central with a Crownline 220 surf, known for its incredibly cramped engine compartment. Here's how we managed to install a heater in what seemed like an impossible space. (Click to go to Video)
The Challenge
The engine compartment of the Crownline 220 is notoriously small, making the installation of a heater seem like a daunting task. However, with a bit of creativity and know-how, we turned this challenge into a success story.
Choosing the Right Heater
Given the space constraints and the climate where the boat would mostly be used, we opted for a compact heater model. This heater is so small that you could almost install it anywhere there's room for your hand. You can find the heater here: Xtreme Heaters Small, 400 Watt Heater
Installation Process
-
Mounting: We found just enough space on the back wall of the engine compartment to secure the heater. It was a tight fit, requiring teamwork to hold the heater in place while we screwed it down.
-
Heat Distribution: The strategic placement of the heater allowed us to blow heat directly across the back of the boat, where cold air tends to enter through the outdrive, exhaust, and manifolds. This setup ensures that the heat circulates efficiently, keeping the entire engine compartment warm.
-
Electrical Considerations: For boats without shore power, we showed how to ingeniously run the power cord outside. We installed a waterproof plug on the side of the boat, making it easy to connect to an extension cord or home power when the boat is on the trailer.
Sealing the Deal
-
Fresh Air Vents: These are necessary for regular operation but become heat leaks in winter. We demonstrated how to cover them using non-sticky shrink wrap tape to prevent heat from escaping and cold air from entering.
-
Exhaust Management: Similarly, we sealed the exhaust to prevent cold air from entering, which could otherwise cool down the engine components.
Tips for Efficient Heating
-
Seal Every Gap: Just like you wouldn't run your home heater with windows open, sealing the engine compartment is key to maintaining heat. This not only saves energy but also extends the life of your heater and engine.
-
Attention to Detail: Every small hole or gap can lead to significant heat loss. Use materials like shrink wrap tape, which are gentle on your boat's finish but effective in keeping the warmth inside.
Conclusion
This installation proved that even with limited space, you can effectively winterize your boat’s engine compartment. By choosing the right heater, strategically placing it for maximum coverage, and sealing off potential heat leaks, you ensure your boat is ready for cold weather storage. Remember to register your heater, check your owner's manual, and perhaps most importantly, enjoy your boat knowing it's well-protected against the chill.
Stay warm, and happy boating!
