Before you buy the propeller for the boat motor, you need to have some knowledge of its parameters and components parts.For example, the diameter, which is defined as the circle which describes blade.
Another property that must be taken into account - it is slipping.This characteristic appears because of the run-off water from the blades, and displays the difference between the actual propeller pitch and those given in the passport.From slip depends the efficiency of the motor.The smaller the value, the greater the efficiency.
Under normal conditions, slippage may not exceed 18%.Below are listed recommendations to help solve problems related to engine speed (when the actual number of turns different from those indicated in the passport).
And do not forget about the disk against.This term refers to the relationship of the blade space and circled.
And, of course, the most important parameter is the propeller pitch.From this characteristic will depend on the load, which is supplied to the motor boats and, respectively, the propeller.That is, there is a linear relationship: the more step, the greater will be the engine to produce revolutions, and, accordingly, there will be more movement speed.In this case, the diameter of the screw assembly is reduced proportional to the pitch.This means that the larger the last, the smaller the first.
So, as promised, we consider the solution is quite common problems.What if the real number of revolutions higher than that indicated in the passport?It is necessary to increase the pace.By increasing it to 2.5 cm, readings turnover decreased by 200 units.If the actual turnover is lower, the need to do exactly the opposite.
There is a company called Michigan, which produces not quite standard propellers.Produced by these blades outboards different parameters such as the diameter and the ratio of the disk.Use these products is desirable only after consultation with experts.
Next will be presented recommendations to help increase the range on Gliss, as well as a decrease in planing speed.
choosing the screw propeller, should take into account the ratio of the disk.For example, the company's products are capable of Michigan Wild blade with minimal loss of speed increase disk ratio.It should be noted, and 4-blade propellers Solas.Under the characteristics these units will reduce the speed when the motor will give the maximum speed.
Well, if you want to experience the maximum speed of your vehicle, you can use the following tips.First of all, it is better to use a stainless steel blade.And best of all, to the motor unit has been ventilated and polished.This combination of parameters provides a significant increase in turns.
lovers of high speed and walking on fishing rivers will be interesting to a propeller as Michigan Ballistics.With it you can increase the efficiency to the maximum.This is achieved thanks to the 3-blade system.
Thus, following the advice of modest, you can understand the range of products and select the propeller that is right for you.
