1972 43' GulfStar Trawler electric conversion begins.
First step is to refinish the bottom. Some blister repair and glass over the exhaust ports and unused through hole fitting.
Need to remove the diesel engines and epoxy coat and paint the bottom to get ready for launch as soon as possible.
I will tow the boat about 20 miles in the water to my house where the electric conversion and topside restoration will happen.
With all the weight I am removing I am a little concerned about ballast and stability.
I have no idea about expected performance.
It will likely not be fast.
I want to mount 15 300W solar panels to it. When the boat is not in use I plan to feed the solar power to my home.
I will use salvaged Prius motors for each shaft. I will weld the axle differential rigid and use MG2 (larger traction motor) via the 4:1 gear reduction to the propeller shaft.
I will couple the boat shaft via a rigid mounted thrust bearing to the Prius half shaft.
The extra motor (MG1) inverter bridge will be used for a solar charge controller boost and a single phase house inverter/ battery charger.
Battery capacity is TBD. The batteries will be the most expensive part of the conversion.
