    Hardest engine to work on????

    What do you consider to be the hardest outboards to work on? I've basically only worked on Evinrude OB's but am considering opening a small shop to work (mostly as a hobby) on some local boats/motors. Just wondering if there are any you would suggest shying away from if someone brought one by?

    1988 V4 110 HP. After all frustration and rebuild I finally got to move accross the lake today. I still had a similar problem (no WOT) until I removed the engine cover and then it ran fine. Put the cover back on and it does the same thing. Needless to say I fished today with no cover but...

    Carb question

    88 Evinrude V-4 Low speed orifice (on both carbs) doesn't have a screw. It looks like something has been hammered in place. I first thought this was the cause of my poor performance (barely pulls) until I found a leak at the fuel connector. Just curious to see if the orifice description was...

    Just finished my rebuild, and all went well. I did however end up with a couple of vacuum lines I didn't get marked... One small line out of the by pass cover, and one off the bottom of the carb base plate (lower port side). Engine starts great, and runs good, just the occasional back fire...
