    E150STLCUR bogging under load

    the el cheapo carb kits (not oem or sierra or old aquapower/red rhino) and horrible! the gasket material disintegrates and leaves you picking pieces out of the myraid holes in your xflow carbs. very well could still be gummed up. the timer is getting full advance after around 1/2 throttle? cam...

    Wits end again - 75 V4 115. Will an oscilloscope help??

    those grounds do NOT look clean. wouldnt hurt to do a continuity check on all of them. not sure but if the powerhead isnt grounded, it might effect the pack. also very possible its coils as it sounds like cutting in and out on less than all cyls

    1993 Evinrude 60hp

    is this a quickstart motor? i have one 1993 motor with quickstart most arent until 94' but whenever someone says its running rough and high, makes me think its not coming out of quickstart. stuck open t stat, bad temp switch, bad diodes in harness etc.

    E150STLCUR bogging under load

    get new OMC kits. make sure your cam roller/throttle cam situation isnt giving it too much fuel too early. as racer said it could be shot piston skirts, stuck ring/s etc here. very common on crossflows.

    1985 Mercury 25xd starting issues

    i believe the throttle plates need to just start to open when the cam roller hits the center of those 2 lines on the throttle cam. now, it could also be your starting point and throttle plates closed aka just start to open immediately PAST the marks but consult your service manual to find out...

    1985 Mercury 25xd starting issues

    oh boy no not really. that block was a nightmare for me as it was swapped onto the more modern ignition (1994 on up). was a side project for a friend of mine, and he eventually made me give up haha. if your motor has its original non-computer ignition, it will be WAY easier to set up. throttle...

    Check valve / recirculation replacements? loopers and crossflows

    no. they are so delicate 80% of the time they cannot be restored. tried all the tricks, including my ultrasonic after a week in chem-dip many times. 8/10 of them sort of come around, but not quite the original flow.

    Check valve / recirculation replacements? loopers and crossflows

    i rebuild about 15 OMC powerheads a year. I was simply asking if anyone has done this as its simply a 1 way valve.

    Check valve / recirculation replacements? loopers and crossflows

    Anyone ever try replacing the check valves with el-cheapos from ebay/amazon? The prices are outrageous @ 105ea. plus the ride. I am talking about the recirc valves going from the intake manifold to the cylinders both port and starboard. For example, doing a looper V4 and they take 4 of them...

    1988 48 special carbs

    compression tells you NOTHING about crank case compression/vacuum. 2 stroke acts like a pump. compressions tells 1/2 the story. remove head to inspect cylinders.

    Piston tool for Chrysler 75 hp 757HB

    your saying wiseco builds in the extra .0003'' (per your example)? I always thought they needed extra clearance for the greater expansion than stock cast

    Piston tool for Chrysler 75 hp 757HB

    with Wisecos it needs to be bored a few thou over to make room for the larger expansion. can't just swap them in on old worn out stock bores!

    1970 Chrysler 70hp outboard motor

    always squirt some lube of your choice down the cylinders (a lot) if you dont know how long its been sitting! id take the carbs apart or at the very least off to make sure bugs/dirt daubbers didnt make a nest in the reed cages. if they did you will be sucking in lots of sand

    Solid repair shop for boring force 85 cylinder

    RI/CT shop here. Just to be clear: 97% of outboards i rebuild (40hp and larger anyway) are BORED and finish honed. You CANNOT hone that out with a dingleberry and hand drill. A shop can with stones, but then you just have a very worn cylinder and the motor will not last long. I send all my...

    yamaha fourstroke crank bearings

    now wait im sure you had a typo there, but just to be clear 7 thousandths is written as .007'', not .7'' which is seven hundred-thousanths! Again im sure you meant .002''-.007'' just thought i'd make sure! But if that one bearing is .006'' you should be fine, no?

    1976 25hp Johnson ignition question

    getting back to original ignition question: i suppose the ignition coils are the only difference on these from the smaller ones, thus the magneto charge coils are called "drivers". the ignition coils must be on these to magnify spark as opposed to a system without them. Never measured voltage at...

    did you put the gasket on upside down and backwards? should have a hole in the gasket and in the air silencer base for idle air relief

    yamaha fourstroke crank bearings

    what does the service manual say? i like to hear it from the guys that made the motor from the ground up what clearances they like unless using aftermarket stuff with their own clearances.
