Boat Motors

Most modern boats are propelled by an engine and fewer people prefer sailing them. Only tradition enthusiasts choose the old way. Boat motors will give the boat’s quality and security that a sailor, a fisherman or a family needs when enjoying a vacation. Knowing how they work will prevent unfortunate accidents or undesired financial expenses.

The three key components of boat motors are: the propeller, the engine and the drive system.

The propeller is best to be chosen by a professional. It usually has to match the boat in order to obtain the best performance, in terms of both acceleration and speed. Propellers should be cupped towards the back of the blade to avoid the slipping of the propeller – it should go right through it. This slipping will create air behind the propeller which damages and reduces the boat’s acceleration. Generally, it is better to choose stainless propellers that have high performance and longer resistance than to pick an aluminum one.

The most popular engine for boat motors is the four-cycle internal combustion gasoline engine. This type should always be well ventilated to avoid explosions or other accidents that gasoline may produce. For larger ships of commercial purposes or other sport vessels it is best to acquire a Diesel engine which will not generate any explosions but which will surely be a lot more expensive.

The drive system can be inboard, outboard or inboard/outboard. This leads the engine’s power into the water and controls direction.

The inboard system gives good balance to the boat but, because of its size, the boat will lack inside space. This system is best suited for those driven by speed and boat power. Although handling and fuel efficiency will still be a problem. Moreover, you have to take the whole boat to a repair shop and it is a lot more complicated to get it fixed thus more expensive.

The majority of outboard boat motors has a two-cycle stroke engine and are perfect for powering small boats, offering good fuel efficiency. With a four-stroke outboard, balance between the boat and the motor’s weight should be carefully considered. The outboard system is low cost, easy to carry, easy to get it fixed and it takes up little space off a boat’s interior. Many companies still manufacture two-stroke outboard engines, because of their light weight. Four-strokes can come out light but the price is much higher. Fuel efficiency for outboard systems are preferred by those who go on long fishing trips, fishing charters or travel for business.

Inboard/outboard systems have the engine located inside while the other components are outside, maintaining the balance of an inboard system. The major drawback is the expensive preservation due to its complexity.
