When the winter chill starts creeping in, the all-too-familiar sadness of the end of boating season follows closely behind. Preparing your boat and all its equipment for winter can take time, but it’s important, and luckily, winterizing your Seakeeper is simple!
Your Seakeeper needs to be prepared for winter if any of its components or its sub-systems will be exposed to freezing temperatures during winter storage.
Winterizing your Seakeeper only requires five simple items. Make sure to gather all these items before you begin.
First thing’s first – close the seawater intake seacock that supplies the cooling system. Next, you want to prepare the seawater strainer. Open the seawater strainer and remove the screen. Clean the screen and strainer housing of any debris. Remove any water that’s in the strainer housing before reinstalling the screen.
Now, does the seawater strainer installation allow for pouring antifreeze into it?
YES – Great! This is going to be easy!
NO – No worries, there are just a few more steps involved.
On your Seakeeper display, tap the wrench icon to open the Settings Page, then press and hold the wrench icon for three seconds to open the override screen. If you are using a Seakeeper 3.5″ display, enter code 4442 when prompted and push the right arrow key until you see the screen with overrides. Activate Seawater Override and allow the pump to draw antifreeze from the bucket, funnel, or strainer. Add antifreeze as it’s needed to ensure the hose end stays submerged in antifreeze and no air is drawn into the seawater pump. Continue to purge antifreeze through the system until you see clean, undiluted antifreeze coming from the discharge hose. Then, deactivate the seawater override setting on your display screen by tapping the checkbox again.
If you just used the strainer body to add antifreeze, then simply close the strainer. If you removed the suction hose to add antifreeze, then reattach the intake hose to the seacock and tighten the hose clamps. Finally, reattach the discharge hose to your overboard drain and tighten the hose clamps.
Make sure the seacock remains closed until winter is over and your Seakeeper is returned to service. When you’re ready to hit the water again, simply open the seacock valve!
Taking the time to properly winterize your Seakeeper and boat means you’re less likely to encounter damage in the spring and you’ll be ready for stable fun as soon as your hull hits the water!
