Regarding 40 hp Yamaha 4 stroke on 14' Lund. I expressed a concern to
the dealer that I couldn't troll slow enough with a 40 hp for
trout/walleye etc. He suggested installing a trolling plate to slow the
boat down. Later however he mentioned that some people don't recommend
using a trolling plate on a 4 stroke.

Anyone using trolling plates on a 4 stroke? Any comments would be
appreciated.
