I have a minn on my 21 seapro walkaround mounted on my outdrive,i love it.when the water goes flat it is nice to stealthy troll .It does have an advantage when the fish are high and spooky.when waves are 2 foot or less i can troll against the waves max 2.6mph.when the waves kick up i use the minn with the waves and main motor against the waves.Mine is 55# 24 volt older model.batteries last 6-10 hours depending on setting.Its also great if you want a drift and the lake is flat when everyone else is out of luck you are moving and covering the water you want to at the crawl speed perfict fore erie deries and harnesses.
