1. A marine drive for propelling a marine vessel in a body of water, the marine drive comprising:
a motor housing having a first housing portion and a second housing portion which together define a motor cavity;
an electric motor nested in the first housing portion and being configured to cause rotation of an output shaft extending from the first housing portion;
a vibration isolating joint that couples first housing portion to the second housing portion, the vibration isolating joint comprising an isolating connector assembly having
an elastomeric member clamped between the first housing portion and the second housing portion and being configured to limit transfer of vibrations from the first housing portion to the second housing portion, and
a compression limiter that prevents over clamping of the elastomeric member during assembly of the motor housing.
