I have a similar situation that I need help with. My first mate, bless her heart, "got distracted" while casting off the stern line, and (you guessed it) it got caught in the prop. NObody else realiezed what had happened. I put the boat in reverse and started backing up, but after a few seconds the motor quit. I was able to start it another time or two, but as soon as I put it in either forward or reverse it died. After that the little button on the throttle control that disengages the gears stopped popping back out like it did before. Now when I try to start the engine there is no response at all, no clicking, no turning over, no nothing. The batteries have plenty of charge in them, I can raise and lower the sterndrive easily. IT seems to me like there might be some kind of safety lockout at work, but I don't know about that. This is an old boat, 1979 with a Mercruiser 888 sterndrive and a single handle control Mercontrol #C-37782A1. I took the prop off, but couldn't see anything amiss there. I took the panel apart as much as I could to look at the control, but I couldn't see much there except that there is what appears to be a small (1/4"?) vacuum tube attached to the bottom side of it. I couldn't tell what the other end of that vacuum tube was attached to, but its not just flopping loose., so seems to still be attached wherever it goes to. This all happened about three weeks ago, and I need to figure something out so that hopefully I can get it started and winterized before the weather turns. Thanks in advance for any help or info you can offer.
