My first post! Re power for a new to me 1973 Seafari. After reading what
others have done and not wanting to overload my boat I am thinking about
the new 2014 90hp e tec pontoon model to get the gear reduction to
turn a larger prop (maybe four blade).. My fishing is mostly trolling at
2 1/2 mph most of the day and hopefully being able to plane at something
above 20knots going in and out. Only have the 30 gal tank and may wish
to try a few overnights............
