I want to put a trolling motor on my '86 Bayliner Capri. It is a 19', deep v-hull fiberglass boat. How much thrust do I need from the trolling motor, and does it matter if I mount it on the bow or on the transom? I am leaning toward the bow because it does not look like there is much room on the transom, but I could be wrong. Any help or suggestions are appreciated.
