I'm undertaking the major task (for me anyway), of removing my old OMC Seadrive, installing a swim platform/transom bracket and a new Yamaha 150. My boat has some type of aftermaket controls, maybe Morse, but I haven't noticed a brand name on them. The tilt/trim button is on the throttle lever and the ignition swith is stand-alone mounted in the console. When I purchase my new outboard will I have to buy the Yamaha controls, or is common to convert this type of controls from one brand to another? Also, if anyone can give me any tips on mounting this transom bracket, it would be more than appreciated! Thanks, Treb...
