guys please help the newbe to chose a engine for his first boat

[Spi D]

First i want to say thanks for your time guys i realy mean it .
to be honest i am not a fan of speed and i was not aware pulling a sky will need so much power . I will use the boat with my family and friends for non thriling water experiance like cruising up and down rivers and mainly fishing so power and speed is not important for me .the important part is to be as good as possible on the fuel so i can aford to go out and actualy do it.so as long as it is not slower then the current ( so i am not in 1 way street) i am happy

The Glastron is not the right boat for that. Designed for speed it need to move forward at good pace to at all perform as meant to.
