| Post subject: | 1990 - 2.3 Cobra |
I have been helping a neighbor get his boat going and a few more have been pulling their problem children out as well. One neighbor has been stumped for over a year. He has a 1990 170 Horizon with a 2.3L (ford) Cobra outdrive. (It has been about 5 years since the boat was actually running. ) He just cant get it to start. When he got it, it had a bad starter which he took to a local rebuilding shop and replaced it. Tried to get it started and started down the path of diagnosing. attached a fuel can directly to the pump, Made sure if you pump the throttle it squirts fuel. He replaced the cap, wires, points, coil, plugs etc. Still no luck it just a sputters dies and it seems to WANT to start. I had a question that is bugging me. The starter rebuild shop mentioned that some boat motors run in the opposite direction to their car equivalents. Is this true ? What direction should this engine turn ? (perhaps his rebuilt starter is cranking it backwards) Does anyone know the firing order ? (I want to make sure his wires are on correctly) |

Most run in the same direction as a car. They can be order "reverse rotation" for twin engine applications. It sounds like clogged idle jets or other passageway in the carburetor. I would buy a carburetor kit (preferably from NAPA or similar and not from marina) and rebuild the carburetor. |

Is the OMC 2.3 the same as the Merc 165? If so, my buddy had similar probs with his. I documented it here: http://www.smwebhead.com/phpBB3/viewtopic.php?f=11&t=11921 Hope it helps. |

I suggested he rebuild the carb as well. My gut is telling me it is plugged up and that it needs to be rebuilt from sitting all that time. Since he replaced the wire I have to confirm they are on correctly. If it is like a car the firing order for a straight 4 cyl should 1342 correct ? I will have to figure out what position is #1 on the distributer (plan to use the finger test for TDC). #1 should be front of the engine or back ? |

It is a descendent of the 2.0 used in the Pinto/Bobcat/Mustang II. As noted your first step is to rebuild the carb, make sure the fuel system is clean, maybe you should remove the cover for the sending unit on the tank and take a look in there. You may need to get the tank cleaned. |

Thinking the same thing. We actually bypassed the tank all together. We connected a external fuel tank to the fuel pump (std mechanical) so we didn't have to be concerned with what was in the existing tank. I'm going to push him to rebuild the carb. Interim im going to check to make sure he put the plug wires back on correctly. Thanks |
