Review YAMAHA Oem Snowmobile Engine Motor Splined Crank fits ENTICER 250 1977–1979

The Yamaha Enticer 250 motor, model number 8H4-15100-00-00, is a mid-sized engine that was produced for use in various watercraft applications during the late 1970s. This particular engine features a two-stroke, single-cylinder design, which was a common choice for personal watercraft during this era.

The crankshaft of the Enticer 250 motor is an essential component that plays a crucial role in powering the engine. It is a splined crank, which means that it utilizes splines on the connecting rod to transmit power from the crankshaft to the piston. This design provides increased strength and durability, making it suitable for the demands of marine use.

TheEnticer 250 motor's crankshaft is made of high-strength material, likely either steel or aluminum, to ensure the engine can handle the rigors of continuous operation on the water. The engine's dimensions are not provided in the model number, but it is known that the crankshaft is approximately 381mm (14.96 inches) in length and features 14 splines on the connecting rod.

This crank is supported by bearings at both ends. The crankshaft main bearing is designed for durability, made of a high-performance bronze material. The crankshaft counterweight bearing, on the other hand, is responsible for balancing the reciprocating forces of the engine.

Additionally, the Enticer 250 motor's crankshaft is equipped with a crankcase ventilation system. This system helps prevent negative pressure from building up inside the crankcase, which can lead to issues like crankcase explosion.
