5hp overheat & stall problem ?

[Dan in MASS]

I have a 5hp Mariner outboard. I believe it is a 1994 model. If I run it in the water for more than a short run it suddenly sounds like it loses power and stalls. To me it seems like it over heats. The cover over the motor seems hot and it smokes a little. How can I fix this ? I bought the boat a couple months ago and only have taken it out three times. The first time I didn't go out far enough for it to happen and the last two times it did. I am new at this boat motor stuff but I am very mechanically inclined. Please tell me how to fix it. <br />Thanks, Dan

Re: 5hp overheat & stall problem ?

If you're going to do your own work, get a manual. You're going to have to replace your water pump. But if you've run that motor repetedly with that overheat problem, you probably have serious cylinder and piston damage.<br /><br />Is it a 2-stroke or 4-stroke? Oil???<br /><br />Finally, a lot of first timers think it's okay to run the motor for a minute or two out of the water. It isn't. You burn up the water pump that way.<br /><br />Cross your fingers that you still have something to work with. If that motor stalled and you couldn't pull it over, you probably have a big problem. If it still turned over okay, then you may have gotten lucky.

It's a 2 cycle engine. It pulls over good. It refires after it cools off for a couple minutes. When it refires it has full power. <br />,Dan
