hi darren
i can give you any help you need about bait boats because i have built 2 of my own
are you going to use the boat on a lake which can become choppy?
because if you are you will need a bit of weight to the boat and the best way to do this is to have a lead acid battery which are heavier than nicads and they have slow drain so the boat will not just die in the water because the battery has run out
with the motor you can just mount it on a small piece of wood and glue it into the hull with epoxy resin
i do advise to put a deck for electrics but also put them in a sealed container with a 1/4 hole for the electric wire to come out
also do you know what electrics to use
hpoe this helps and if you are unsure of anything please feel free to ask questions
