I'm thinking about rigging something up to control at least FNR and maybe throttle on the outboard so that it is mounted on the Tiller.. As it isn't in the easiest location to change whilst docking etc..

Has anyone come up with anything before??

I found this online but seems $$ for something that should be fairly simple to make.. powertiller.com

On my last yacht I had an outboard mounted on the stern on a bracket. The engine was never used for steering and the friction was tightened so it did not rotate. The engine was a 8hp Mariner with the usual gear change on the side. I made an extension out of a section of a fishing rod with a pivot joint at the gear change. The end of this extension finished up in the rear of the cockpit and it was easy to change gears when recovering a mooring etc. I never bothered about the throttle.
On my yacht tender outboard it has a long tiller with the handle that rotates to control the throttle. The carburetor has a cord that adjusts the rpm and it revolves around the tiller. I also have a kill button on the end of the tiller.
