thrust bearing?

[killarney_sailor]

I have been sailing for more than 30 years and have run into something totally new to me - a thrust bearing. I have been told that it is a wonderful device and dramatically reduces the noise and vibration from a diesel. Anyone have one of these on their boat?

Like that?
Thats about the smallest marine thrust bearing I can find, other than thrust bearings that may be in your transmission.
Thrust bearings are designed to suppot high axial loading (fore and aft loading). You probably have to have some serious HP to need a thrust bearing, or for a thrust bearing to have any real significant advantage.

or is this more your speed?



There may also be a thrust bearing in your engine.

I have to correct myself....
Pretty much every engine has thrust compensation built into it, even little outboards. I think what you are asking about is an independent thrust bearing in between the drive and the prop.

I haven't seen it, but I think it is like that one from Evolution Marine. It is not in the engine but a separate unit. Allows the engine to be mounted on soft mounts because it does not have to resist the push of the prop into the shaft. Just wondering why I had never heard of one - perhaps they are just on largish boats/engines?
