Electric motor to power a dinghy
Chuck,
It is not necessary to have a big heavy battery if all you want to do is run to shore and back. Lawn tractor size batteries will do what you want at a reasonable weight. If that is too heavy go with two small 6 volt batteries. I leave mine in the dingy and hook to a charging line connected to my house batteries that keeps the dingy topped off and ready to go. I find this much better than fooling around with a finicky 4 hp motor. Ron |

Electric motor to power a dinghy
Well it certainly helped my outlook. I have looked at the Walker Bay (Great,
now something else to lust after.) and it clearly has less water resistance than our Livingston, though as the L is technically a 'multi-hull' it may not be as great as one would think. I found your motor, I think. Forty FOUR pounds of thrust, and weighs 34 pounds to ship (The 'Waterfowl' model... right?). That's manageable. The Series 24 battery runs between 72 and 105 amp hours and 41-50 pounds in weight. It sounds as though your use is similar to ours. This is more like what I had hoped for, including the prices of things. We do have ample power on the trawler. Though we don't have an independent generator, we do have a large 'cruise generator'. We use an inverter overnight and when we up-anchor and get out of the bay and up to some sort of speed we cut that in and recharge. Adding a little 24 to that would be nothing. Is your 24 of the larger amp-hour persuasion? I'm ready to roll on this. Thanks - Chuck Rick Morel wrote: Chuck, I'll add in my 2-cents. Over the past 3 years I've used a Walker Bay 8 with a 40-lb (or is it 45-lb?) thrust Minnkota and type 24 battery. No complaints at all. I added a trolling motor connector to the motor and battery, and to my house bank so the trolling battery can be charged. Once it is, it's plugged into a small 10-watt solar panel for "maintenance" charge. This on a sailboat with solar and wind charging, and occasional engine run or at a marina. I would think on a trawler charging would be no problem. The trolling motor is very light, the battery not so light. However, the type 24 is not bad at all. Less trouble to transfer actually, than a 3.3 HP outboard I had. It's large enough to give 2 hours at "wide open", which I seldom use, and supposedly about 5 or 6 hours one notch below. All I can say for sure is using the durn thing a lot during 4,000 miles of cruising, I've never run out of juice. Most of the time the closest to shore I could get was about a quarter mile. Did a lot of exploring, sometimes 4 or 5 or 6 miles according to the GPS. During that time we bought an inflatable and the 3.3 HP outboard. The Walker Bay turned out to be the best almost all the time. The only thing the inflatable was best for was getting in and out while diving. The outboard was used on the Walker Bay some, but as above, it really was more trouble. It did give about twice the speed. Bottom line I guess is I sold the inflatable and outboard and kept the Walker Bay and trolling motor :-) Hope this helps!

I leave it at home but rowing a Livingston is no slice of Heaven. So I want power again, but more reliable and hassle-free for the limited use. Does anyone have experience using an electric trolling motor this way? What kind of motor and/or battery rig did/do you use and how heavy are the parts? I'll appreciate hearing from experienced users. Thanks S/V Final Step http://www.morelr.com/coronado/ |

Is there some advance in 4 stroke technology of which we're unaware? Perhaps, but you should be. The 2- stroke has, for some time, been known to be very polluting. There is a push to go to 4-stroke, and I think California has passed some regulation in that regard. Our daughter is a card-carrying NOAA tree-hugger. I would not be able to conceal buying (or even continuing to use) a 2-stroke, and yes, I *am* afraid of her! (:=D |

I believe he said reliable and hassle free.......plus 'quieter' would be a
bonus for me...not to mention cleaner. anonymous wrote in message ... On Mon, 13 Oct 2003 02:45:00 GMT, "Don White" said: I'd go with a nice little 4 stroke Honda or Yamaha outboard. When his primary concern is weight? Is there some advance in 4 stroke technology of which we're unaware? |

WalMart's Auto Department battery rack has a very nice 75AH size 24
battery marked "Trolling" for $39.95. Bought one today for my little electric..... On Mon, 13 Oct 2003 17:14:52 GMT, Chuck Bollinger wrote: Well it certainly helped my outlook.

Minnkota sells a bunch of electric trolling motors that would work, but you have to deal with a battery which may weigh 50# or so, much heavier than the 4 hp Johnson, (I have one, a 1987 model that weighs 33#. I love it!) although not quite as awkward to handle. I once read something that said 15# of thrust is approximately equal to 1 hp, but then a whole bunch of posters chimed in with the information that thrust and hp were as different as apples and chipmunks, so..... I have a Minn Kota Endura 30 on Near Cove (Walker Bay 8) which pushes it just fine. I just replaced the 22NF (25lb) with a Series 24 (35lb), but if weight is a problem go with the the 22NF.

I'm convinced. Bought a new 75AH 24 battery and shiny new prop for my
$12 Minnkota 35 from the thrift shop today....er, ah....tempered with a new set of aluminum oars, just in case...(c; If that don't work, I'll put the 3HP Yamaha someone gave me on it.....
