Re: Frozen North - lucky escape!

Congratulations and well done on your unassisted escape! Now a question: Once you got it started why didn't you go west to open ocean then turn left till it got nice and warm?? Mid 80's here today, clear sky, winds ESE @15.

Re: Frozen North - lucky escape!

I own a 2gm20f as well, and learned a little about cold starting through experience. I took possession of the boat about 6 years ago in Maine in October. On the start of my trip home, we had a couple of mornings with ice on the deck, and I had real difficulty starting the engine. Eventually I learned that it really likes to be on full throttle when starting in cold conditions. Totally makes the difference on my engine ... on a cold November morning I used to crank forever to start with throttle at idle, some reduction on half throttle, but with full throttle, it reliably starts in seconds. You may well be aware of this, but maybe it will help someone who was as naive as me.

btw, someone posted that 12.1v corresponds to 20-30% charge. I think that comes from room temperature data. Resting voltage is a function of temperature, dropping at cold temperatures. There may well have been a lot more charge in the OP's batteries if they were cold. Battery meter is best, otherwise SOC estimation is just a wild guess without knowledge of battery temperature and a cold-temp SOC vs voltage curve.

Re: Frozen North - lucky escape!

Oh yes at -4C 12.1V is about 60 to 65% charged. My mistake.

However, that makes it, even more so, the case that the engine SHOULD have turned over, and it didn't. The OP should troubleshoot his cold cranking problem.

Re: Frozen North - lucky escape!

I doubt very much that the battery was at -4 c. I would think the inside of the boat was probably at least +5 - +10 c. However if the OP is/was using something like 40 weight engine oil it could make for some pretty slow cranking.

Re: Frozen North - lucky escape!

You didn't mention a cell phone as a back-up to your VHF. Your attempt to call the Coast Guard would only have resulted in them calling for a tow from an outside party, unless you declare your life to be in imminent danger. Belonging to C-tow and having a cell phone would have brought a boat to your location for a jump start, or a tow, as required, with no cost to you. Just a suggestion.

Re: Frozen North - lucky escape!

Unfortunately there is no cell reception past Croker Island.

To all those who are taunting me to move south ... I am coming soon!
