yamaha 150 2 stroke alarm

[tjm]

Took my 2003 Yamaha 2 stroke out the other day and the alarm starting to sound. This means it was either oil or overheating. Shut down for a few minutes, filled the engine mount oil tank with emergency switch. Started up, alarm still sounding, started to head in and alram shut off. Ran around the lake for a bit no problems at full throttle. Slowed down and put in idle with in minutes it was alarming again, would not shut off. At home checked all wire connections with oil injection system, seems to work. Any way to verify? What about the overheating part? How do you verify? Any help would be great.

Re: yamaha 150 2 stroke alarm

My impeller, poppit valve or anything with the water pumps has never been changed. Where do I find the water pump parts? How do you tell if they need to be replaced? Any help would be great. Any schematics would aslo be great.
