R&D Flexible Engine Mount (Shear Type / 250 - 563LBS / 3/4" Stud)

R&D flexible engine mountings have been designed and engineered for the rigours of marine engines. The flexible engine mount has added features of being fail-safe, working within controlled limits and able to withstand a roll-over test. The mount is soft vertically and at right angles to the crankshaft to isolate vibrations, as well as being able to cope with propeller thrust. It is a low height mounting to absorb vibrations better. Maximum clearance between the underside of the height adjusting nut and top washer must not be more than 10mm. If more height is required use a spacer under the mounting casting.
