    78 mercury 900 90hp

    The rectifier may be bad. You can disconnect the (2) yellow stator wires from the rectifier and check the resistance with a meter. If you don't have a meter, check for sales at Sears. You can get a very serviceable digital VOM for under $20 and they usually have something on sale. I picked...

    45hp shifting reversed????

    Maybe the "bump" between Reverse and Fwd is worn out such that it'll slide back to Reverse then Neutral. At least it was an easy fix. Pretty odd, though, with the shift cam looking like this:

    1965 mercury 1000 not grounding?

    Sounds like one of your problems is a lack of proper ground. The powerhead is at negative-ground via the black battery cable, connected right to the side of the block. But, the upper cowling, front and rear cowling supports, and lower cowling are rubber-mounted for vibration reduction. So...

    1966 mercury 1100 solid state distributor swap/conversion

    The 1250 and 1000SS both have a similar-style distributor which will separate from the distributor drive, same as your 1100's dual-points distributor. The body of the distributor is different, though. But still has the same 4-bolt pattern. The distributor in the eBay link isn't one of those...

    evinrude Lark 6 - 40hp, Surging. (MFG gypsy)

    Looks like your motor is 'circa 1964. It certainly could be a weak fuel pump; there are diaphragm kits available and it's probably a good idea to do a rebuild. If it turns out to not be an issue with the fuel pump, you'll probably need to pull the carburetor for teardown/inspection/cleaning ...

    Water Pump Flushing Attachment Merc 1500

    Sorry, I thought yours was the 1500 with the older L/U! Too many posts to remember I reckon! :facepalm: So I'll retract the "morpodite" description, you have a Wonderful 1500 with a lovely L/U! :lol: Your comment jogged my memory; the old, old engines had a metal screw that went into...

    1988 Mercury 70hp Rebuild, finally got my Block Back!

    Well, since these are aftermarket replacement bolts, you'd have to rely on their engineering to have confidence that they make a satisfactory product. You could send them a query asking about the thread length. The original bolts are 'stretch' type and the longer threads are probably part of...

    1976 Mercury 1150 Idle Adjustment

    To increase idle speed, you would adjust the "Idle Stop" on the "Stop Bracket" that mounts to the front of the distributor. Don't touch the "Throttle Stop" or Spark Adv" screws unless you're doing a more extensive tuneup. Loosen the locking nut and turn the screw inwards (CW) to increase idle...

    Swivel Bracket Broken 1969 Mercury 7.5

    The cover that interferes with access to the top mounts is held onto the lower cowling by 4 screws, 2-per-side. Just pull the cover and you'll be able to get to the upper mounts. HTH.............ed

    Fluid in float...

    Yes, they are; the floats in all 3 carbs are the same. Haven't personally seen a lot of failures in the newer-style plastic float, but things do happen! The hollow-chamber style of that float would make it more prone to getting a leak and filling with fuel, whereas the older...

    Swivel Bracket Broken 1969 Mercury 7.5

    A freshwater motor is certainly worth fixing, and it increases the chance that you won't have too many issues pulling the motor mounts out of the saddle. I found a pretty good pic of the mount assy on eBay, I'll post it here so you've got an idea of what one looks like. The only special tool...

    1988 Mercury 60HP

    Here's a "quick & dirty" carb clean that sometimes works if you just have some material lodged in the idle circuit: remove the silencer assy in front of the carbs so you'll have access. Turn the idle mixture needle clockwise until lightly seated, count and record how many turns that took...
