As for solar charger, great idea unless the boat is stored indoors, which we do.

You may not need to go fast, but most alternators do not put out anywhere near their full output at low engine RPM.
My advice is to check your battery voltage with an accurate meter before you turn the battery switch on the next time the boat has been used for a day (thus the battery should be charged), then sat at least overnight with the switch shut off (no load on battery). If it's fully charged, you should see 12.6V; 12.4V means 75% charged, 12.2V would mean 50% charged and anything in the 11s is really bad. You should always aim to store the boat starting with 100% state of charge.
