2 Stroke Vs 4 Stroke Outboard Motors

2 stoke vs 4 stroke outboard

If you are purchasing a new motor for your recreational boat then you will need to spend some time choosing between a 2-stroke outboard motor and a 4-stroke outboard motor. Both of these types of outboard motor have their own pros and cons, and it can ultimately depend on your budget and your personal preferences. Here are some quick pointers to help you to understand both types of motor:


2-stroke outboard motors

2-stroke motors are generally less expensive to buy than 4-stroke motors, and they are usually less costly to maintain because the components are widely available. Because of their simple design, they are very easy to get to grips with, without prior technical experience. If you are looking to buy one of these motors second-hand, then it is usually very easy to find a good model at a decent price. Most models offer fast and accurate acceleration, and they are lightweight, so they are unlikely to create weight issues on any boat.

Unfortunately, 2-stroke engines are responsible for more pollution than 4-stroke models, especially when they are non oil injection models. As well as potentially polluting the water, some models can produce a lot of smoke and create far higher levels of noise pollution than 4-stroke motors do. Occasionally, 2-stroke motors can be difficult to start, which can cause some issues for anglers if they are a long way from civilisation. Some areas also restrict the use of 2-stroke motors.

4-stroke outboard motors

4-stroke motors produce much less smoke than 2-stroke motors do, and they are also less of a pollution risk. They are very quiet and smooth when out on the water, meaning that aquatic and marine creatures are less likely to experience significant disturbances. These are some of the main reasons why 4-stroke motors are accepted on all bodies of water. Because this sort of motor is very reliable, owners rarely report trouble re-starting motors whilst out on the water. However, if repairs are needed, they tend to be more expensive than repairs to a 2-stroke motor would be. As these engines do not need a mix of gas and oil, they offer  better fuel economy than 2-stroke outboard motors are able to offer.

4-stroke motors are generally heavier than 2-stroke models, meaning that it may not be possible to use one on a boat which has weight restrictions. These motors can also be more expensive to buy, even when buying second-hand. As technology on these motors is constantly being improved, it can be much harder to find a good value, top-spec motor through second-hand channels. Because there are significantly more parts in a 4-stroke engine than a 2-stroke engine, it is much harder for amateurs to be able to maintain their own engine. If a part malfunctions, it can also be much harder to source a new part. Because these engines are larger and heavier, it can also be more difficult to transport and store these engines when they are not in use.
