I have a Yami 200 HPDI that runs awsome, but will not draw from the expansion tank in the boat automatically. I have to use the override switch to pump oil from the expansion tank on the boat, to the small tank mounted on the egine. I have replaced the oil sending unit on the motor with a new one. I know the new one works because if the tank on the motor get low, it will put me into rpm reduction mode.
Thanks in advance for any insight on this.
