That was easy
take it to Flordia.Just kidding. Yes, if it will drink. Take the hose off the through hull. Place it in a bucket filled with anti-freeze and start the engine. If it does not start sucking the anti-freeze up stop right awayI used to jam a funnel into the hose and secure it with the hose clamp. Have someone else start the engine and keep pouring anti-freeze into the funnel. It works. You should also run some fresh water through the engine to get the salt out, if you sail in salt water that is.
