My wife and I purchased a 1978 Montauk 17, which came with a 2001 100hp Yamaha fourstroke, which runs fine and has given me no problems. I am admittedly new to this type of boat, grew up on a small pontoon.

Several people at our marina have told me that motor is too heavy for my boat and that I need something lighter. Is there any truth to this? If so, trying to figure out if the Etec 90 or YamahaF70 is a better choice. Any thoughts? Its usually just us two cruising, occasionally 4 people. We dont venture out in rough conditions by choice.
