Hello, i have a yamaha enduro 15hp 2 stroke. 3
hey Chaser2
Have you tried to turn it over with the spark plugs removed and in neutral? This sounds "fishy".. remove the cowling... spark plugs OUT... try to turn it over.. see which way the flywheel tries to turn..THEN try turning the engine (KEY OFF/IGN OFF) by using your hand on the flywheel.. DO NOT turn it backwards,,,you will "kill" the water pump impeller.. IF you cannot turn the engine over by using the flywheel. you should be able to "feel' what's happening.. If you feel the pistons or rings are stuck... try liberally spraying some WD40 into the cylinders through the spark plug holes... reinstall the spark plugs and let it sit until tomorrow... If it is still locked up, you can always remove the head and see whats happening.. all you will need is a new gasket... and some Permatex 80064 High Tack Spray-A-Gasket Sealant. DO NOT use any form of silicone sealant - PERIOD!!!!!!!!!!
After you have sone all this, reply to me and let me know what you have found... thanks
Yamaha Malta outboard won't idle
Hey Frank, has anything happened to this outboard? It might just be time for new spark plugs..if it is not running well, it might be time for a carb clean and set. ..no biggie.

Not enough information, but there are two things I didn't read about you checking. Make sure the fuel quick connection on the engine (and possibly the fuel tank) is locked all the way in first, Then see if your fuel pump is working. Disconnect the fuel line from the carb and, holding it in a gas can, have someone turn on the ignition. If It's an electric pump, it should start running fuel, if mechanical, they'll have to crank it a little to get fuel going. If you get plenty of fuel that way, your float in the carb could have gotten stuck, or something in the line got into it.
