Lifting engine to replace motor mounts

Post by earlylight »

If your engine is tucked well back under the cockpit sole and you merely wish to raise it up sufficiently to replace the motor mounts, try this trick. Place a deflated basketball, volleyball or soccer ball under the engine's oil pan.. Now, just inflate the ball sufficiently to get it raised the required amount for the work ahead. This trick works quit well.

Say now, interesting idea. I'll try it but am curious if I should take the shaft end of the business apart first. What's your experience.

YES....disconnect the shaft coupling from the transmission BEFORE you loosen the engine mounts.

Would new mounts reduce engine to boat vibration issues? My Perkins 4-108 rattles all that can when it runs, especially at lower rpms.

Mounts seem old.

There are a number of things that can cause vibration including:
Lose engine mounts (either at the engine or the bed logs)
Old and tired engine mounts
Poor shaft alignment
A worn cutlass bearing
A shaft that is not true (bent)
A bent prop or a prop out of balance
A badly fouled prop
