YANMAR 4JH5E Diesel Inboard Engine 54 hp
There is no flimsy engineering on the Yanmar 4JH5E marine engine. It has a gear-driven camshaft that operates push rods for the eight overhead valves and a cast iron cylinder head and block. The engine has a crossflow head, with the exhaust manifold to port and a relatively low-pressure inline fuel injection pump to starboard.
The Yanmar 4JH5E marine diesel is in essence a four-cylinder version of Yanmar’s three-cylinder 3JH5E. Adding another pot increased the engine/gearbox weight by 15 per cent but the maximum power is 38 per cent higher and torque is 35 per cent greater – and at lower rpm. As is the case with most four-cylinder diesels versus their triple counterparts, the substantially lower vibration is not only kinder to accumulated flab but also your hull if of timber construction.
