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.

Looks beautiful, but the weight is too great. Even without the charger it would
be something like 230#.

I'm beginning to get the picture that, for practicality, the answer I am
receiving is "No".

Thanks for the reply.

Thanks for the reply. 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.

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!

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

I totaly agree with that post. I have a 8 foot Bombard with a Minnkota
30 and a 32ah gel battery that I can pickup with one hand by the
handle. I put the motor on the transom and hang the battery from the 2
big butterfly screws. I also added a plug in the line that I can
connect to the boat to recharge. I siliconed a small digital voltmeter
to the battery so I can keep an eye on the voltage.
I am planning to add a small solar panel on a post at the back of the
dinghy so that I can get some charging when I leave it at the dinghy
dock for hours whilst visiting some place.
It doesn't go very fast but it gets there silently, smokelessly and
smelllessly (is that even a word?)

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

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
