Re: [Electric Boats] Motor mounts

Mike and Eric on separate post - thanks. You confirmed what I was thinking.

I seem to recall I used the lightest (load) marine motor mounts I could buy. I think the one I bought had a load of 150 lbs but, I could be wrong on that it might have been more. The motor after all weighs all of 47 lbs and was probably still over kill. But, it was the lowest load availible. The motor mount is probably more useful for helping to align the motor to the shaft than vibration. As compared to the diesel which has a lot of moving metal parts swinging around the vibration is minimal with EP.

As folks are mounting electric motors versus ICE are you finding the need to have motor mounts for vibration reduction?

I am assuming that the electric will "run" smoother but also know that the electric motor and larger prop should have more shearing potential.

I am considering the difference between R&D motor mounts - small shear (model 800-041) and shear loaded (800-010). There is also just a general compression mount (model 800-036) which should address vibration but seems silent on the shearing.

Here is their website with dimensions and general tolerances.

Thoughts from the group?

Capt. Mike - s/v Bianka - curious on your Thoosa installation since that is the motor I am going with as well.

As always, many thanks for any advice from the group.
