I have a 2003 200 hp Yamaha Vmax 3.1 L fuel injected ob. While I was running on the water ,the constant alarm that I believe is the oil alarm went off. The oil in the resorvoir was low and I refilled it. The alarm stopped. It came back on a few minutes later. If I trim the engine up so the prop is just under the water it runs with no alarm. If I drop it down lower ,it alarms. Any ideas? There is water coming out.
