Evinrude 150 gas leak

[jutila]

I recently acquired a boat powered by an Evinrude 150 "Spitfire" series engine. When pumping the fuel prime bulb, gas starts leaking from the side of one carburetor (top on right bank). The gas comes from what appear to be fillers in the casting on the side of the carburetor, an odd place to see fuel weeping out. I have photos if that would help.<br /><br />This apparently continues after the engine runs, too, because I noticed a sheen on the water when I stopped the engine. (I don't want the Coast Guard to cite me for an oil slick!)<br /><br />So, does this mean a carb rebuild? If it does, how does one go about resetting it with six of those babies working together?<br /><br />Thanks for the help!

Hello jutila and welcome to iboats.<br /><br />Sounds like you have a stuck float. That allows the gas to keep coming until it floods the carb and pours out the vent screen. I you don't know when the last time the carbs were overhauled, then I would suggest that you have all the carbs done and the rest of the engine checked out as well. You may save yourself a big chunk of change down the road.<br /><br />Good Luck and keep us posted.

Re: Evinrude 150 gas leak

Thank you for the response - good advice. After writing my initial post, I realized I didn't include the year of the engine - 1993. The hour meter shows 185 hours, and by the looks of the engine and boat, it seems accurate. Probably more hours accumulated on a kicker.<br /><br />IF I chose to go after the rebuild kits myself, can you suggest a good source? I've done plenty of automotive carburetors, but when there are six lined up, it's a bit more intimidating. I assume there's some type of timing/vacuum instrument to ensure that all six are working together.<br /><br />Again, I appreciate the response!
