Small Outboard Motors

Portable outboard motors are of course the most common way to propel your boat across the water. These units are completely self-contained with everything that is needed to motorize your boat and they are especially designed to hang on the rear of your boat to not only move it, but to steer it as well.

They are further designed to raise the motor up out of the water when there is danger of damage or even getting seaweed and other aquatic plants and foreign material fouled in the “screw”. When the boat is in motion the operator of the boat will sit in the rear by the transom and not only control the speed of the boat but also steering it as well.

There are different types of portable outboard motors and not all of them will be good in every situation as you may already realize. Now, you may be one that prefers not to row your boat using oars, so you may end up buying a small motor that is a couple of horse power to get you around your pond or lake. You certainly wouldn’t consider trying to mount a 60 horse power motor on it. It’s far too much and would likely sink the boat before you could even get anywhere. That said, you would want to try to put the smaller motor on a large boat either because then you would be barely moving, if at all.

So there are a number of different things to consider, and of course pricing may be one of those factors as well depending on your budget. Another consideration is whether or not you might want one of the portable outboard motors that are of the jet propulsion variety as opposed to one with a prop. It is said that these get much better fuel economy on the slower speed and so may be something else that you would like to consider before taking the plunge.

The most important thing, is to sit down and think about the type of boat you want to power, then choose the size of the motor based on that and then further choosing from the many different models available on the market.
