I have a 30 hp Yamaha (with tiller) that I want to convert to remote
steering.

Is there a conversion kit I can buy?

The tiller control that came with my used sailboat has a remote
comprising a simple 2-way momentary switch on a 30' cable. The previous
owner used it to steer from the bow when dodging crab pots. I'd think
it'd work on an outboard tiller too. Check out the Simrad TP-10 at
