Warning buzzer-Engine Oil low?
Hello everyone,
Powering our 2009 Hurricane 237, we have a 2009 Yamaha 150 HP two stroke, with 425 hours. Engine has been well maintained and runs great. About a month ago, I got a low engine warning buzzer. The small oil tank ( inside the engine cowling) was a pint low, and the remote tank needed oil. I decided to exchange the existing oil with a fresh batch of Yamalube. I have since taken the boat out three times, about six hours running the engine. Yesterday I again experienced a low oil buzzer. The small tank was about a pint low, but the remote tank was full and did not send oil to the small tank? Is there an oil feed pump that runs from the remote tank to the engine oil reservoir? Anyone still out there with a trusty old Two-Stroke that can provide some insight? Thanks....Lawnie

@Lawnie... There is indeed a pump that will be used to draw oil from the main tank into the small side tank when the oil levels start to drop.I don't own/have a Yamaha, but I do believe that they have an tank float switch that detects it, and triggers that pump to fill the small tank from the main. So it could be a switch problem, or possibly a pump problem.Here are some detailed threads you may find useful.------------------------------------------------------------------------------2010 Hurricane SS 188 OB

Its most often a bad sender or float as nquirk mentioned. Its usually a pretty easy fix by replacing the unit inside the tank.

I just went through that. 2002 24' fun deck with 2002 yamaha 150. after having a couple experts check it, they decided it must be the CDI which costs about $2000. I decided to do some checking myself. I checked the continuity on the boat wire harness and found that the yellow wire had none. It turned out to be that some if the wires were corroding, so I replaced that wire harness and it fixed the problem. It also fixed the periodic tilt problem.
