I'd have to check my manual, myself, to see the actual procedural step-by-step. But for my setup ('00 250HP OX66), I think it's something like... trim the motor up and put it on the rest, then open the manual release and fill. Trim down and up and repeat. I would 'assume' it's something similar for yours, but that's not guaranteed.2000 Yamaha OX66 250HP SX250TXRY 61AX103847T

that system was funky and there have been some updates and parts changes along the way.
