Was at the Algonac Harbor Club for the weekend Antique Boat Show. On return to Jefferson Beach Marina cruised through Metro Sunday morning. In the back basin the starboard engine over heat bell went off. Temp was 280 degrees. Probably the Impeller. Shut it down and limped to the south wall. I am with Boat US for insurance which comes with $50 towing which will get you about 50 feet of tow. But, purchase supplemental tow insurance of $500 for I think $79. Called US Tow and they were there in 30 minutes. Towed me to Jefferson Beach and into my well. Tow charge was $337 but no charge to me. We all hate insurance premimums but supplemental insurance paid off for me. By the way, the Boat US tug driver was very experienced, professional and prompt. A good experience and saved lots of bucks.
