45hp evinrude problems

[ttouch459]

i have a 1996 45hp evinrude outboard motor that starts jerking abruptly if it goes above 2000 rpm's. it sounds like it is starving for gas. the guy i bought the boat from says he replaced the fuel pump, and i replaced the fuel line, any ideas what this might be? i tried to clean the fuel filter screen, but i am not sure what the best thing to do that with is.<br /><br />any thoughts would be greatly appreciated.<br /><br />thanks.

Is the tank venting properly?<br />If you squeeze the primer bulb when it starts coughing will it recover?<br /><br />Tried spraying pre-mix from a bottle directly into the carb? This should tell if its fuel or ignition related.

TTOUCH459 I am in agreement with KEVINH make sure the tank is venting properly. I would use carb cleaner or something like it to clean the fuel filter screen.

Re: 45hp evinrude problems

make sure your carb doesnt start to choke that could do it

Can you get it above the 2000-2500 RPM mark? If not sounds like its dropping into S.L.O.W. mode. <br />If it is not overheating, could be a bad temp sensor or powerpack problem.
