Are you looking for a trolling motor or the amazing, kick
you in the back, power of a 250 HP monster?
With some manufacturers offering a range of outboard
motors with 17 different horsepower levels there is a power level to suit all
Read studies and reports in the magazines, and also ask other users, of the
reliability of the new or used motor that you are considering buying. What is the guarantee, if any?
Repair Service and dealers
Depending on where you live or where you operate your boat, what back up is offered from dealers
with a depth of knowledge and commitment to service.
Ask around your friends and other users about the reliability of starting of any
motor that you consider buying. You obviously require fast consistent starts in hot or cold
Based on past experience with pull-start outboards, many users will not even consider
getting a model without electric start.
Some twenty years ago one company introduced microprocessor ignition. Is this
something that you should take into account?

There are outboard motors on the market that use lower gear ratios so that a bigger
prop can be used.
There are engines available that weigh from 10 to 30 lbs less than other motors with
the same power.
Is there an easy-to-use freshwater flushing device that lets you wash salt water out

Up to a few years ago, 4-stroke motors and the sea were a
very poor combination, but the situation has now improved dramatically. The protagonists for 4 stroke claim the
Most outboard motors have 2-stroke engines, like lawnmowers. 2-stroke engines are
lubricated by the oil that is mixed into the gasoline. The exhaust from a 2-stroke engine is smoky and contains
unburned oil, which pollutes the water.
On the other hand, 4-stroke outboard motors have engines like the one in your
automobile. The lubricating oil is separate from the fuel. It is not burned, and the exhaust is intrinsically much
cleaner and friendlier to the environment.
The EPA has mandated that all outboard motors sold after 2006 must meet the minimum
pollution standards that currently are met only by 4-stroke engines. It was important to us, philosophically, to
choose this option now.
Oil and maintenance
You fill the oil the same way you would fill a car. Checking your oil is also the
same, using a calibrated oil stick. And the filter is easy to replace. Changing the oil and applying a little
grease at key points will take care of your annual maintenance.
No mixing of oil and
It's very convenient not having to mix oil and gas. With 2-stoke engines, I always
had problems with this. For example, say your fuel tank is partially full, and you want to top it off before you
head up river. How much oil do you add?
Although many newer 2-stroke engines have oil injection systems so you don't have
pre-mix the oil and gas, this feature is not always available on the smaller models. And even with oil injection,
water pollution is still the main issue.
4-stroke engines run quieter than 2-stroke engines, especially at slower (birding)
speeds. This can make a big difference in your comfort level.
Better fuel economy
At slower speeds, 4-stroke engines can get twice the gas mileage of 2-stroke engines.
It's not so much the cost of gas as it is the increased range. With a 4-stroke, you can go further up river on the
same tank of gas and see more habitat.
No fouled spark plugs
2-stroke engines tend to foul their spark plugs and then sputter and stall. They need
more attention to the spark plugs to keep them running properly. Again, this happens more at slower speeds, the
speeds birders will tend to travel at.
While 2-stroke engines rely on gas or air to carry a thin oil film to critical
components, our four-strokes bathe every internal component in oil under constant pressure. Ports in 2-stroke
cylinders and pistons accelerate piston and ring wear. But there are no intake and exhaust ports in a 4-stroke
cylinder or piston, so they can run with tighter tolerances for longer life.
How easy to find replacement parts and spares ?
If you need e.g. props, pistons, starters, ignition gear, gears, tanks, bearings,
seals, caps, carbs, shafts, springs, are they easily available?
Vintage Outboard Motors
Enthusiasts of antique and vintage outboard motors generally
fall into two categories. First, there is the enthusiast or sportsperson who buys an old motor at a yard sale with
an eye on restoring and actually using it. Second, there is the enthusiast who performs a complete, authentic
restoration for the pure satisfaction of returning a vintage piece of machinery to its original condition. Often
this second motor will become a static display, displayed at the occasional boat show. There is a splendid
association that you can contact at vintage outboard
motors where you can read about other
enthusiasts and find out where they meet.
Using your outboard
It is always recommended that you read, and follow meticulously, the operation and
maintenance guidelines provided by the manufacturer in the owner's manual.
This list does not list all manufacturers of outboard motors. If your company should be
