I ordered a Saito 91 4-stroke from Horizon, and it is supposed to arrive in the mail tomorrow.

I'm curious, did you guys who used a similar engine do anything special when mounting it? I am a little concerned with the vibrations that a large 4-stroke will produce, and I'm thinking of using a Du-Bro motor mount with the little rubber grommets to absorb vibrations. Of course, this motor mount will not work with the existing mounting holes. In order to use the Du-Bro mount, I'll either have to drill new holes (and somehow install the blind nuts in the existing firewall) or perhaps install a 'sub-firewall' to mount to the existing firewall (at the expense of extra weight of course).

Perhaps I'm being too paranoid with regard to engine vibrations. Did you guys just use a regular glass-filled mount for the 91 4-stroke or did you do something more extravagant?

Thanks in advance,

Dave
