    Got home last night and took a picture of the serial # on the carb which I posted below. The rubber hose from the fuel pump to the carb is hooked up and is free of any obstruction since I was able to blow thru it (just used my breath). My ol eyes read the serial # as being 17082403 3543...

    1988 4.3 OMC with Rochester Quadrajet carb issue

    The quadrajet carb on my 4.3 OMC was replaced ~4 yrs ago due to an air leak after a rebuild which wouldn't allow us to adjust the low idle mixture jets. The mechanic intentionally left the linkage off of the throttle side of the carb so the 4 barrels wouldn't kick in and said that would give...

    1988 OMC Cobra 4.3L Shifting issues

    Main Question: Can a sticky or worn remote control shifter at the helm cause the shift assister on the engine bracket to hold the ESA arm on top of the lobes when shifting INTO gear? I have read many posts here stating the ESA should only actuate when you are coming out of gear and that make...

    1962 Evinrude 18 Hp Model 15036M

    Hey everyone, My father passed down this 1962 Evinrude 18 Hp outboard to me. It had been sitting for a couple years and rolled over nicely when pulled the cord. I mixed new gas 24:1 and got it fired up in a trash can full of water. Ran fine. I took it out of the water and checked the...
