Outboard motors dominate today’s boating market. And with good reason. Today’s outboards are powerful, quiet, reliable, easy to service, and offer excellent power-to-weight ratios, as well as outstanding corrosion resistance.
Why are outboard motors so unreliable?
Why are boat engines unreliable? Many boat engines are “unreliable” because they are not taken care of correctly. While some boat engines are less reliable than others, there are common engine issues that appear from overuse, ill-maintenance, or low-quality materials.

Are outboard motors more reliable?
Outboard motors are known for their reliability. The drawback of this motor style is its power level. Larger boats simply cannot rely on one outboard motor alone, unless you want to spend your life savings in gasoline.
Why do boat motors not last long?
First, diesel engines typically last longer than gasoline engines. There are two main reasons for this. One, at a given boat speed they turn fewer revolutions, usually about a third fewer. When an engine turns fewer revs per mile, pistons make fewer trips up and down the cylinders and valves open and close less often.
What company makes the best outboard motors?

Which is better 2 stroke or 4 stroke outboard motor?
The fuel efficiency of a 4-stroke motor can be 50% better than that of a 2-stroke motor with the same HP. As for environmental concerns, 4 stroke outboards produce far less harmful emissions, which can be as much as 90% cleaner than those from a similar sized 2-stroke motor.
Which Yamaha outboard is the most reliable?
According to FishTalk magazine, the Yamaha F150 produced after 2005 is often considered “one of the most reliable four-stroke outboards ever produced.”
How often should you change spark plugs on 2 stroke outboard?
PartsVu recommends religiously inspecting your spark plugs annually or every 100 hours, replacing them if they are fouled or damaged, and always replacing them every 300 hours.
Is 1000 hours a lot for a boat?
The number of hours that a marine engine runs is very dependent on the amount and quality of maintenance over the years. The typical gasoline marine engine will run fine for the first 1,000 hours. It is at this juncture that the engine starts to exhibit small problems.
Is 500 hours a lot for an outboard motor?
In the Midwest, 500 hours is “high,” even though it isn’t. I wouldn’t bat an eye buying a motor with 1,000 hrs…. but the price should reflect it’s use, because the next guy won’t pay top dollar for it either. Big 4 strokes are good for 5,000 to 6,000 hours.
Is it better to have an inboard or outboard motor?
Because it will usually weigh less and be a more-efficient design, an outboard motor will typically deliver better fuel economy than a sterndrive. … However, most sterndrives can not be tilted completely out of the water, while most outboards can clear the water when tilted all the way up.
Are outboards more reliable than Inboards?
Inboard motors, for example, tend to last longer than outboard motors. And maintenance requirements, based on hours of use, often favor the inboards. Inboards on average can run 1,500 hours before tune-ups, while the outboard counterparts typically run 750 hours before service is needed.
