Electric motor to power a dinghy
We have a trawler and an 8' Livingston which we use as a tender. Generally we
go back and forth to shore but occasionally will explore a small cove we may be anchored in. I've been using a 4HP Johnson (2 stroke) but it is failing, as am I. 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 |

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 had a 7' Livingston that I am happy to be rid of, as it was too heavy to handle and tended to like to take on water over the bow when power was cut. I replaced it with an inflatable, which runs a little bit wetter in big waves, but I will take it out in stuff I wouldn't even consider doing in the Livingston. |

I guess I'll stick with the Johnson, for a while, anyway. I agree with your comments about the Livingston 'box', but as much as I'd like to have an inflatable, I really don't have the need for A) speed and 2) range. Putputting to the dock and back is about it, or setting the odd crab pot near the boat, or looking around a small bay. Would be a waste for an Avon, like hooking Secretariat to a wagon for toddlers. |

Chuck, the only other thing I can think of is going with a Honda 8hp
electric start. Weight about 100lbs. I thinks it's the only one, that small with electric start. You would think that as the population gets older building electric start 2hp + 4hp would make sense.

The trolling motor battery is more hassle and WEIGHS MUCH MORE than a
little outboard. Then there's the 14 hour battery charging every time you use it. What? You got no AC out in your anchorage to charge the battery? Neither does the dingy dock...dammit.

I'd go with a nice little 4 stroke Honda or Yamaha outboard.

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!
