Are you using the chain-and-sprocket shaft coupling arrangement T'struck provides, or some other coupling arrangement? Did you use standard motor mounts, or did you hard mount the reduction gear rails more or less directly to the hull?
I have a T'struck kit operating nicely on a test bench, and have not yet started an installation. Our local installer, as recommended by T'struck, told me on the phone that they would need to use motor mounts and some other items not provided by T'struck that he did not detail in that conversation.
So, the few reports in this group over the past few weeks by skippers of recently launched e-boats of uncomfortable levels of vibration who are using the Thunderstruck motor kit, and T'struck reduction gear got me wondering again about the best way to mount the system, and also to couple it to my shaft prop.
The chain-and-sprocket arrangement is not common in this application. It's stated that this arrangement can help compensate for slight misalignment between reduction shaft and prop shaft, but I'm skeptical. Can that approach be as good as, for example, a flexible shaft coupling such as those from R&D Marine or from Vetus? (These are more expensive, I recognize.)
My existing diesel motor mounts are shot so I can't reuse them. And my existing shaft coupling is a solid-style, split type, so would require precision alignment. Would using new motor mounts allow enough adjustment to ensure a precision alignment?
Any success stories out there?
