Is there a certain height requirement for the oil injection tank in comparison to the outboard? This would be for a 150 mercury in a Bayliner Trophy center console. The current tank (was) fastened in a hanging shelf at the tansom about 2' (left of) from the outboard. The holder for the tank broke and I want to sit (fasten) the tank on the floor of the same area...about 12" lower. Will this affect proper operation of the oiling system? Thanks.
