If they are "pull to open throttle", then pretty much any remote will work, But you'll need to transplant the electrics as they will have slightly different wiring configurations / loom plugs at the engine end from manufactuer to manufacturer. The mechanism inside is identical.
I used a Tohatsu remote to test my Yam last weekend, it's the same unit in a different box.
Teleflex do a nice cheap "mechanical only" one if you can transplant the electrical string......
If thats any help.
