Hey guys and gals, this is my first post. Seems to be a lot of good info on here so I thought I would ask a simple question. Can I put a kicker motor on my 1989 Procraft boat? And how big of a motor do you think I should get? It's an 18' boat and pretty heavy. The 150 horse Mariner is just too big to troll with. Any ideas will help. Thanks!!
