    1992 115 hp Yamaha carburetor float height

    I have a 1992 V4 115 HP outboard with two carbs. Each carb has 2 floats and 2 needle valves. I have removed and cleaned the carbs but would like to set the float height. Any idea what that spec is?

    twinscan floscan help needed

    Jon, Is this the meter that you have? If so, are you saying that only the starboard engine is showing a GPH reading when under way or it just that the totalizer Gallons used is incorrect? How difficult would it be to swap the twp sensors to see if the problem follows the port sensor? I agree...

    cooling system pressure check

    Other than checking the cylinder compression (on another thread) I am also testing the cooling system for a possible leak. I got a loaner Stant style pressure tester from Autozone and then checked online for directions on how to use. (http://ww2.stant.com/repository/documents/JB-1164_20091.pdf)...

    Crusader 8.1L compression test?

    What is the correct procedure for doing a compression test on an 8.1L EFI engine? On an engine with a distributor you would disconnect the high voltage center wire at the distributor and ground it. Since this EFI engine has coils for each cylinder, should I just disconnect the spark plug...

    Crusader 8.1 V-drive Coupling

    I am in the process of replacing the coupling on one of my Crusader 8.1L V-drive engines. I was able to remove the old coupling using a wheel puller I loaned from Autozone. What is the best procedure for installing the new coupling on the shaft? Should I coat both surfaces with anti-seize...

    8.1L exhaust gaskets

    Perhaps someone can explain the purpose of the wing plates used between the manifold and riser, and riser to elbow on the 8.1L Crusader engines with heated risers. The diagram I have seen shows a pass-thru stainless steel wing plate sandwiched between two gaskets. Since the riser and manifold...

    Mercury 350 help

    Several years ago my son picked up a Mercury 350 (35hp) and it has been in storage ever since then. Never used by him. We don't have an Operator's manual and I can't even figure out how to remove the cover. I also have no idea what year it is. The only serial number I have found is 2258146...

    Evolution of modern practices in todays newer boats...looking for a few answers

    Attached is a picture of where the anti-siphon valve is located on my 1990 Silverton with Crusader 454s right on the top of the fuel pickup tube. I have heard that some owners have removed them, but this is not a good idea for the reasons already cited by others. Erich
