Inboard engine mounts

[MarkR]

I'm trolling for information on the engine mounts (or engines for that matter) Seacraft used on thier inboads in the mid '70s.

I'd like to replace my mounts, but can't find replacements. I don't want to replace the entire assembly, just the component that does the work with the isolating material in it.

I believe the mounts are original, there has just been a few chevy small blocks bolted and rebolted to them. So, if I even knew who's engine the original was (crusader, marine power, rolls royce?), I could research it from that end.

...anyone replaced these pieces?
