Hello, I have a 2004 - 150 HP, 2 cycle, carbureted Yamaha Outboard and had the alarm go off this weekend. I pulled the boat of the garage and started the engine for the first time of the spring using a hose and muffs. I have used muffs a hundred times and never had a problem. After about 10 minutes of running the alarm sounded. The engine was never running at more the an idle except for a few seconds when it was choked at start up. I checked to see if water was pumping and found nothing unusual. The pee stream seemed normal. When the alarm sounded I immediately shut the engine off. Turning the key to the on position, without starting the engine, produced the alarm again. The on-board oil tank was full and the external oil tank was half full. I believe it was an overheat alarm as the shaft of the motor felt warm. I connected the hose to the hose port near the cowl and let water flush through the system. The water coming out felt warm. A little while later when I turned the key the on position the there was no alarm. The T stats and impeller were changed in August or September 2009. Any thoughts? Should I be concerned or is something that should not be a problem when the outboard is run in the water? Thanks

I have a 2004 Yamaha 150 2 stroke. I noticed an oil leak the other day and would like help finding the source of the leak. It is a 2 stroke so there is no motor oil. The oil that is leaking is not the same color as the 2 stroke oil I put in the oil tank. It is an amber color like normal automotive motor oil and thicker than 2 stroke oil. The leak is minor - no puddles or anything, just residue that has leaked down the outside of the motor. The red marks on the photo indicate where the oil is leaking and where it has settled. The motor runs fine and I have not noticed any performance issues. The tilt and trim work normally also. Can anyone help? Is this a crisis and I shouldn't use the boat until it is fixed or can I wait and fix it later in the season? I don't want to miss the last half of summer while my boat sits in a repair yard, but I also don't want to create a bigger problem. Thanks
