Selecting propeller usually takes precedence over the size of propeller with original machine.2. The pitch of propeller is the most important parameter of ship speed, followed by diameter. As the name implies, the bigger the pitch, the faster the speed! But we should also follow the following points: the ship's own weight, or heavy load to use small pitch propeller, ship light, speed fans can choose large pitch, the bottom of the V, deep V and shallow V will also affect the speed of the ship!Propeller is a vulnerable component. There are several points for attention in the use of propeller.1. Rubber sleeve is used for shock absorption and protection of gear box. It can relieve vibration at the moment of engine start-up by rubber sleeve. When the propeller rotates at high speed, it encounters reefs, wood, or entangled with ropes and fishing nets, reaching a certain limit. Rubber sleeve will slip to protect the engine. Drive shaft and gearbox assembly! So the propeller can not be used for a long time under load or overload, which will cause damage to the engine!2. The blade of the propeller bends or breaks when it is impacted violently. In this case, please put out the fire immediately, stop traveling, hoist the machine to check the damage of the propeller, then rekindle the engine, check whether the engine is damaged or not. If you can start and sail, please come ashore immediately or go to the nearest maintenance station to repair the machine professionally and replace the propeller.There is a big gap between water navigation and land travel climate and rescue. For your safe travel, we sincerely recommend that customers have spare propellers and propeller fittings on board!
