Re: Motor size
I had(going now with a new Suzy DF140) an old '87 115HP 25" Yamaha on my 20' Seafari. The best WOT i hit was 34MPH.
Up here in mostly choppy NE days for fishing/trolling, it served me well. I will admit, on a flat calm day (which does not happen often) ..... it really feels dog slow!
So you main question, "will a late model 115 Johnson push this boat with 60gallons fuel and 3 adults". Sure! Will you be happy with the performance, maybe. Might help your decision, if someone has a 130HP to see if there is a significant diff in the performance #'s.
I like the rule of min HP = 75% x 175HP(max for my boat) = ~130HP.
Also note, the Florida boys seem to like their HP. So they might feel that the 115HP is underpowered, where in NE it seems to be more of the min HP.
Hope this helps ... Good Luck - Nick
