Bison electric outboard is a trolling motor that I have had extensive experience using on the Norfolk Broads.
In addition. to the following review, I have attached a Youtube link below this article to a video that demonstrates the capacity that this Bison electric motor got tested by myself.
The Bison electric trolling outboard motor is for small dinghies, canoes, kayaks, lightweight fishing boats, and rowing boats. In my particular case, I tested the electric motor over several weeks on a Broom Saturn speed boat which weighed more than 400kgs. Hardly its intended purpose, however, the waters were calm, short distances to travel and having a supply of solar panels and 12-volt leisure batteries. It was too tempting to resist.
The first thing I was to realise was that after I used the electric motor, I was always left with a flat battery. Even with the introduction of two 100 watt solar panels, I was unable to fully charge the battery even in the greatest sunshine. As good as the solar panels were, it became apparent very early on that what was essential was a 12-volt leisure battery that could be removed at the end of the boating session with great ease. The battery had to be portable. In addition, the battery was heavy and I would strongly recommend paying the extra for a purpose-built leisure battery case that is designed to be portable. Once you are done boating, you can pull it out and take it away to recharge. Solar panels are great but they serve to top up batteries rather than deep cycle charge.
With multiple speed settings on the Bison electric motor, it is very true to say that going slow is always your best option. Just stick it on the lowest setting and bring some patience into the boat trip. Putting the speed setting on to its highest setting does kick in with some torque and the vessel will respond favourably. However, the power draw is very high and the battery levels will drop immediately. The clue is in the terminology, 'trolling'.
These motors are not designed for racing across the breaking waves of a seashore. They are designed for an additional engine on top of a petrol outboard or for pushing a canoe/kayak along. With a hydrodynamic vessel like a canoe and being sensible with the selected speed, one could expect to cover some miles.
If I went on the lowest speed setting, I was just able to make a journey from Wayford Bridge to Sutton Staithe and then crawl back to the final stages. That was a round trip of approximately 6 to 8 miles. Taking into account the boat was not far from half a tonne in weight. So a kayak or similar would be able to make the same journey with significantly more speed.
If I was to purchase another Bison electric motor, I would use it on a hard hulled kayak, canoe or as an additional outboard motor on a dinghy as a backup or for quiet travel as you may require for fishing.
My only negative experience with this electric outboard motor was I noticed the bracket fixing bolts began to rust. These are where the outboard attaches to the transom of a vessel. I found it odd that they were not stainless steel. To be fair the outboard was left outside throughout the season, however, the corrosion was minimal and possibly may not have happened if the engine had been removed after each use.
One other experience I would like to add is that because it was so quiet to use the electric outboard motor, I recall travelling along the river one sunny afternoon and I heard a slight rustling in the reeds on the riverbank. A beautiful deer poked its head above the reeds out of pure curiosity to see what I was. Normally, the deer would be invisible with the sounds of the thumping inboard diesel engines of boats.
