I would like to know the proper size outboard gas engine that I should
put on a 18-ft aluminum semi-V/deep-V boat.

According to Tracker web site, they stated that the max HP for their
16-ft deep-V aluminum boat is 40HP. I would assume that the max HP of a
similar 18-ft boat "may" be around 50HP (?)

Obviously, this 50HP figure is just the maximum limit. And I may want
something smaller than 50HP to save gas, to reduce noise, to reduce
weight that an electric motor has to pull. But if I go to the other
extreme by getting a very small engine, I may spend too much time
"getting there" especially against the current. Somewhere between the
maximum and the minimum, there may be a horsepower rating that is
appropriate for my need.

Let explain what my needs a
- Put the gas engine in a 18-ft alumimum boat.
- Carry 4 adult males (let's say 750-lb total).
- Use it strictly for fishing, not for skiing.
- I like to drive my car at or below speed limit,
not over it. Likewise, I operate a boat at
moderate speed only.
- Want a quiet engine (I guess I need a 4-stroke
engine).
- Want to save gas money.

What size gas engine should I get? A range of horsepower should be
fine.

Thanks for any info in advance.

There should be a plate on the boat giving the maximum horsepower for that
hull and the maximum number of people or weight allowed.

Bigger engine may not use more gas. Unless you run it wide open. The
smaller engines can use more fuel, as they have to be run in the upper range
of the throttle to get the performance required.
