How are the speeds calculated? What size boat? Current?Originally Posted by gazza2006au

Thanks this is a useful guide.
Heaps of testing videos on youtube with various Haswing models connected to watt meters and hand held gps devices
Any thoughts on the whipper-snipper style trolling motor like this, with a longer shaft: https://www.ebay.com.au/itm/2-5HP-2-...frcectupt=true
Although I'm mainly going on the river, don't want to end up grossly under powered if using electric. If 1hp =55 to75 pounds then 2.5-3hp should be sufficient to get to a nearby ramp (?)
So you have power consumption and speed over ground. What about other variables? Hull? Current? Windage? Is it going to get my 575 30km from the Gardner Banks in 1m swell with chop on top into a head wind with 2 POB and a 14kg red in the esky. Probably not but Youtube

youtube "haswing protuor" you may be surprised... i just watched a video of one pushing a 27 foot commercial boat
Short you're pushing a boat through water not flying a kite in the wind..
If u pick a decent motor with plenty of extra thrust wind would be no factor as the electric motor is thrusting through water and not air, wind would just put a bit more force on the hull which an ekectric motor over the recommended size will just poeer through
Just because the wind is blowing 45kph doesnt mean the current is flowing 45kph which the water is your propulsion force and to be factored in
You're boating in a river, toss a couple of paddles in the boat.
heres a laugh
$1.20 for alitre of fuel = 9kw hours
100amps at 12v =1.2kwh
so 1 litre of fuel = 7 100 amphour deep cycle batteries, minus friction and inificencies from heat and friction
a long shaft 4 hp yamaha is about 2k second hand with a inbuilt tank, significantly cheaper then a 24v electric setup and all you need is a 5l jerry can to run for hours
Small auxiliary/kicker/spare motors are usually more trouble than they are worth, they never get used, never get maintained, and when/if you need them, they won't start, add to that, extra weight on one side, which in a small boat is a big issue, you are just creating headaches.
Could you find me a youtube clip of that?
Cheers Matt
im not the you tube expert
and noelm
i ran a 9.8 tohatsu long shaft on a 4.8m stacer with a high thrust low pitch sail prop and worked well used it to troll as could troll slower then the 70 main engine when livebaiting offshore
Also used it on a 12foot tinny to let the kids use when away on breaks to the coast
nevers a broad statment not everyones lazy and indifferent to their safety and backup devicesand they do work for some
almost every trout boat has a kicker engine for trolling on them
Dakr, I think you are over thinking things. Make sure your motor gets a good overall service and any necessary repairs and have some faith in it. If you can't get past the idea of not having a spare motor then by all means get an electric mounted on the bow as you will find it absolutely the best if you decide to flick some plastics, vibes etc. I e en use it bait fishing these days, my anchor hasn't seen water gor about 2 years. Chasing prawns was another upside, move into position, cast the net and with the remote move away from the mangroved.
So easy move a few metres one way or another, hit the anchor lock and fish an area for 5 mins or so then move on.
They run them because they need to troll VVEERRYY slow, slower than you can manage with a larger outboard. They were popular in some places as saltwater trolling motors back in the day, as most of the larger two strokes hated idling for hours on end. Foule dplugs and all that, safety wasn't always the consideration.
That is the problem with the world tho fuel is just to cheap for the bang it gives its what makes the world go round mechanically we are no where near comparative fuel to electricity and we will need a huge break through like going from Ni-cad to lithium pilymere but untill than battery power wont be as efficent however with solar power u can make recharge for free kind of after the intial investment but that is just like buying a new 4hp 4 stroke outboard
