Change the fuel filter and see if it helps. Disconnect the throttle cable and work the carburetor by hand and see if it helps. (Cables improperly adjusted).

Next, try drawing vacuum through the distributor dashpot and see if the spark is advancing. The vacuum should hold and the breaker plate should move.

Next items would be to check vacuum pressure. Then check fuelpump pressure. Finally the prop can affect the engines top RPM, Thats about all I can think of, Good Luck.

Why does my mercruiser engine die when put in forward?


Something is too close to the coil wire , CAbles(steering and throttle ) either up front or on the engine do flex when moved.Checkthe movement and operating clearnces at both full and idle positions. All tests can and should be done with engine off, due to Dangerous prop exposure. Good Luck and I would like it if you tell me what you ultimately find. _Ned_

Why is it hard to start my Mercruiser 7.4L MPI after a hot run?


Electric choke? Try retrofitting a manual choke. I think the electric choke is closing over a hot engine, thinking that the engine's cooler than it really is. A manual choke will allow you to start it with no choke at all when you know the motor's already warmed up.

HAVE YOU HAD YOU THROTTLE BODY AND OR YOUR CAM SHAFT SENSOR CHECKED OR YOUR AIR TEMP SENSOR ? IT MOST LIKELY SOUNDS LIKE YOUR AIR TEMP SENSOR IS'NT LETTING ENOUGH AIR IN OR OPENING YOUR MASS AIR FLAP ENOUGH WHEN ITS COLD OUT CAUSING THIS.

Good idling speed


This all depends on when you are reading the rpms becaus ethe engine will run faster when you first start it to bring it up to operating temperature than it will drop down to about 700-800 when the engine is warm. i recommend letting your engine warm up, than read your tach and if it is still reading 1000 rpms than reduce it down to 700-800. your ECU will compensate for this when your engine is cold.

this could also be a possible bad Idle Air Control Valve because your engine speed should be regulated by the computer.
