Push starting your boat
I had a Trojan Group 24 that easily started my 3GM30F

Auto-pilot is also nice on long runs. So what happens if my batteries accidently get run down? My old Yanmar 1GM could be han cranked but my 2GM, no. However, while looking into the engine compartment one day while under sail, I noticed my prop shaft was spinning like mad cuz I hadnt put it in gear (Yanmar says put it in reverse). So: maybe not so useless Idea #3727 Can you release the compression of the engine with the decompression levers, get going good under sail with engine in gear an use the spinning prop to sorta "push-start" the engine with you suddenly giving it compression? I might try this next time I am out. Unluckily, your (and our) prop freewheels in forward. If you slam it into reverse, you would try to start the engine in the wrong direction. Best would probably be a solar panel. Turn everything off for an hour or two and even a 12w panel might give you enough juice: 2GMs really don't need much power to start if everything else is in good shape. Changing my mind: Best is two battery banks. Only draw from one at a time, but always charge both. And upgrade any of your battery leads that is less than 1/0. We can start off one of our group 31 batteries during the summer even if it's showing about 11.5v. (When it's chilly, we need better voltage, but I haven't checked it since I upgraded our cables.) -- Jere Lull Xan-a-Deux ('73 Tanzer 28 #4 out of Tolchester, MD) Xan's Pages: http://members.dca.net/jerelull/X-Main.html Our BVI FAQs (290+ pics) http://homepage.mac.com/jerelull/BVI/ |
