Trailer and solar boat
I'm glad I've decided to change out the bearings on the boat trailer. They aren't in bad shape, but the inner seals are gone. I've compensated by keeping everything well greased. The downside of that is that grease leaks out and splatters all over the wheel.
As it turns out the local auto parts place has to order the new seals all the way from Ohio. I'm glad I'm not stuck on the side of the road while waiting for parts to come in. Even though the bearings look good, I'm going to change them anyway. Might as well since everything is all apart. The old bearings look good enough to save for emergency spares.
Some years ago I built a wooden box to act as a sort of lazarette on the sailboat. It held a 6 gallon marine gas tank. The gas motor is long gone and I've been using an electric trolling motor to move the boat. I'm thinking of mounting a second battery in the box along with a charge controller. My 50 watt panel would just about fit on top of that.
The boat currently has just a 30 watt panel. That's been sufficient to run the boat's electronics and the trolling motor. If I use the motor a lot it may take a few days for the battery to charge up. That's not a problem here on the lake. It might be on the ocean.
That's why I'm putting in a second completely separate solar electric system. Both the trolling motor and the boat's electronics are connected to the battery with jumper cables. It would be easy to switch them from one battery to another.
The trolling motor moves the boat at about half the speed of the gas. That's sufficient for moving in and out of anchorages and marinas. In a pinch, it will move the boat for quite a few miles. While not as fast as gas, it's a whole lot more convenient. The motor is quiet and I'm not hauling gas around. Plus, the batteries are charging from the sun.
The best part of this project is that I do it without spending any more money. No, the best part is that it will actually do the job. The money thing is bonus.
