Is it possible to replace a motor mount?
Unfortunately in order to replace these mounts with a different model or brand would have entailed a far more costly and time consuming job due to differing bolt centers for the mounts. The three point design of the Ericson motor configuration is dependent on the rather stiff lateral design of these mounts.
What causes a motor mount to get loose?
One thing I often see that destroys motor mounts prematurely is the lack of properly tightening the stud nuts that clamp the motor mount bracket. If these nuts are allowed to become loose the motor mount bracket or bell housing ears will vibrate over the threads and wear them away to nothing.
How to remove motor mounts on a sailboat?
In order to remove the motor mount lag bolts I used multiple socket extensions, which made this a quicker and easier job. For a 34 foot sailboat this engine room is quite loaded with gear.
Is it bad to mix and match motor mounts?
With a three point motor mount design, or even a four point design, mixing old and new mounts is just a poor choice. One thing I often see that destroys motor mounts prematurely is the lack of properly tightening the stud nuts that clamp the motor mount bracket.
How do you remove a failed motor mount?
Using a socket and long extension, remove the motor mount bolts on the engine side. Then remove the motor mount bolts on the chassis side. Slowly raise the engine using the jack. Check every full pump to see if you have enough clearance to remove the failed motor mount.
What happens when you replace a motor mount?
Not only was the engine sitting far to low in the shaft log, and the shaft was thumping it when the engine was in gear, it was also not passing through either the shaft log or the cutlass anywhere close to parallel. The minute the cutlass was pressed out the shaft sprang up and pressed itself into the top of the strut.
Is it normal to have three motor mounts?
Three motor mounts is not the norm in boat building and almost all engine manufacturers ship engines with four mounts, generally with very good reason. The minute I put a wrench to the front mount, in order to adjust it, and thus drop the shaft from impinging on the top of the strut, the motor mount stud began to spin in the mount.
Where to put scissor jack when replacing motor mounts?
The small scissor-jack is critical on engines like this when replacing motor mounts. The camera angle makes this area look a lot more roomy than it really is. The scissor-jack fit quite nicely between the engine bed stringer and the engine.
