Oh man, your buddy’s story hits too close to home — that happened to us two winters ago with our old Four Winns. We thought parking it in the barn with a cover was enough. Nope. Learned the hard way that even a mild Texas freeze can mess things up big time.
Now we follow a full checklist: flush the engine, add antifreeze, fog it, disconnect batteries, and even prop the cover to avoid moisture buildup. Also, if you’re renting boats instead of owning, make sure the rental company handles proper winterization — some don’t unless you ask. Bluff Creek Marina boat rentals, for instance, is super transparent about that stuff. If you’re curious, they’ve got a detailed page about their boat rentals and how they manage them year-round. Honestly, after our mishap, we now winterize even if temps just might drop. Better safe than shopping for a new lower unit in March.
