    Question How big of a jet motor??

    How big of a jet for a 1448 Jon?

    I use to own a 1648 Lowe Jon with a Johnson 25/18 jet. It had a standup console and would do well on the Little Su, 20 Mile, Kenai etc. Not a speed demon but got the job done with 3 adults. Most would say that this is a underpowered setup. I agree, but the package is very light and if you do not overload it can be done.

    It depends on the boat construction and weight. I have a lightweight 1448 that would sink if I put my 25hp powerhead jet on it. That boat is rated for a 10hp prop and that's all it can handle. We call it the coffin boat.

    If it was me I'd search for a 25 or 30hp 2-stroke powerhead with a jet. An equal power 4-stroke will be too heavy.

    Default If you use a 2 stroke............

    Go with 40 hp at the powerhead. I have setup/ridden in two different 1448s with 40s [25 - 28 jets] and they were both great. I can't comment on 4 strokes, but beware of weight if you go with a 4 stroke. The smaller 25/18 like someone suggested would be okay as well if thats all you could find.
