It is a challenge to get everything to come together with the 3V. On IRV we have right at 100 hours of run time with current mount. On SR 7-1/2 i was hoping to use the mounting similar to the 5V but after 2 variants gave up and went to mount like ORV. Shake is absorbed in rubber bushings, that can be changed to softer or harder. Oil cooler on ORV is mounted to engine mount, on SR 7-1/2 it is mounted to engine. It came out of mount and needed additional clamps and bracing. Ready to try again
