Allright guys, I'm new to the site and this is my first post. In April i bought myself a 2009 Lund WC14 deep-V aluminum boat. Since i got the boat i've been using a 36lb thrust minn kota trolling motor to push me around the lake. After saving some money, i just bought a brand new Nissan 15hp 4 stroke outboard. Now, ive read through the owners manual a couple of times just to make sure i didn't miss anything important. The question is about mounting the motor on the transom. I have it centered and i have the clamp screws tightened (hand tight only). Is that all that is needed to keep that thing tight against the transom so it dont fly off the boat if i hit a big bump? The manual does say that there is an option to drill a hole through the transom and actually bolt (the stern bracket) it to the transom. Should i do this......really dont want to drill through the transom. Or do most of you guys do this?
