It’s like trying to fill an oil drum with a shot glass.

Re: Solar charging
worthless for out on the water
next to worthless for a trailered boat marginally useful for a boat docked or on a mooring for keeping the battery topped off (bc the bilge pump may have been running)

Re: Solar charging
It's basically a trickle charger. It won't help while out on the water. I agree with NJSquatch, invest your dough in a second battery.

Re: Solar charging
You’d need a lot of solar for any benefit, and even then it would be for recharging not for on demand power...
In the RV world where solar is pretty popular, the minimum suggested wattage is 200 watts worth of panels. That typically allows you to replace the power lost in your battery after using the lights and water pump each day... I would think the demands for a trolling motor would be much higher and you’d need even more... Lastly, it’s usually not practical to install solar panels on a boat since you don’t have a large enough surface area to mount the amount of panels needed for any real benefit, other then maybe a trickle charger/maintainer.

Re: Solar charging
I had a small I think 5 watt solar panel on a boat I kept docked in the water. The boat was not self bailing so the auto bilge pump was needed to get rainwater out. Other than that starting a small outboard and running a small fish finder were about the only load on the battery and I used the boat maybe once or twice a week. In my case it kept the battery topped off pretty good but I had a very limited load on the battery...Charlie
