    Help! Removed wrong screw from lower unit!

    I have just finished swapping out an Evinrude Lark 40 for a Sea King 40, both look like identical motors. Last thing to check was the lower unit oil - but I removed the wrong screw, my book says it's the shift fork screw, and that I really shouldn't have done this. Question - is there a trick...

    Help changing out Evinrude lark 40 for Sea King 40

    My Lark 40 died, and I got a good deal for a Sea King 40 that runs great. I'm good with cars, trucks, and tractors, but I don't quite understand the wiring on these motors. I do have a manual, but the wiring diagram doesn't fit. I really just need to know about the kill wire, my electric...

    Help with carb and synch - 1959 35hp Lark

    I was given a boat and motor from my grandfather about 5 years ago. He claimed it had just been gone through at the boat shop and was ready to go. I brought it home and put it in a bucket to fire it up. After a bit of work it ran with lots of smoke but settled down and seemed okay. Took it...

    Water in lower while hoooked to a hose

    Hi all again,<br /><br />I just got my Mercruiser 140 back together, but my oil is turning to milk while hooked to hose in the yard. Since it's not in the water, does that narrow down what my problem might be now? Something simple like a water pump?<br /><br />Thanks for all the previous help...

    which order - lower or upper install first?

    I've just redone my lower end thanks to all the help found here (saved lots of $$).<br /><br />Now I need to know what is te best/easiest way to get it back together. Should I put the lower and the upper together then on the boat? Or the upper on the boat then the lower?<br /><br />Thanks...

    Mercruiser sterndrive help/parts?

    Hi there,<br /><br /> I have a 1973 boat with a mercruiser sterndrive. The lower unit seized up last year, so I bought a used lower for it, only it doesn't<br />fit. I guess the last owner had it rebuilt and didn't tell me. The one I bought has a short eight spline shaft, but my upper...
