Some more updates -
Added a Noco Gen 1 Mini charger with a 110v inlet plug. No more clipping automotive battery charger leads on to my buss bars to charge! This charger will not only save me time, but it's designed to keep the battery healthy. Much better than charging it 2-3 times a season like I did before.
I had a 2hp Yamaha motor which ran great but it was stolen

. It was slightly underpowered for ocean trolling and the internal tank was a PITA. I picked up a 1975 Johnson 4hp for $225 that was sitting for 4 years but started when I bought it. Figured I'd replace the impeller and be on my way...
Unfortunately the drive shaft was frozen in the crank. Took me two days of penetrating oil, tonnes of heat and swearing to break it free. After removing the power head, I had a bunch of gaskets to replace. Long story short, I ended up rebuilding the starter, carb, fuel pump, replaced the fuel lines and plugs, cleaned a ton of carbon from the head and exhaust manifold...etc.
$400 all in and this thing looks and runs like new. I'll take it.
