    Accidentally ran 2 stroke mercury 15hp without oil for an hour.

    Normally the rings fail first, when you run w/o oil. Take a compression test and see what you have. The cylinders should be 90+ PSI and within 10% of each other.

    Old motors DEMAND to be retired when they are 65 years old..

    Actually, OMC recommended that you not flush the old Johnnyrudes after saltwater use. Not sure why.....

    A nice tip but it’s not about stern drive storage in the up position

    Gee, when was the last time you were out boating and had a PTT failure? I have never had one in 50 years. I had some PTT units that leaked down over time, but no catastrophic failures. Whereas your trailering clips are a nice blue color, I believe them to be superfluous.

    Gee, a simple topic, so off base.

    Stringer rotten

    Doesn't it depend on how much flow you need? See what your pump puts out and compare that to a normal livewell pump. If she pumps harder than you need for one livewell, add a tee or valve to control pump output.

    Mercury 2 stroke 4 hp

    A thru hub prop will be pretty obvious. It will have a nut in the center and a tube-like hub around the nut. Tak a look at any Merc prop for 40HP or larger. If you have a thru hub prop, it will look the same, only smaller in diameter. Most OB motors have water intakes in front of the prop...

    Newbie removing lower end on Mercury 115 4 stroke...

    That is a strange place for silicone. Most waterpumps have a stainless steel wearplate with a gasket on each side. These seal the waterpump cover to the waterpump base. Silicone is never required. You should check the parts list on a site like crowleymarine. Most exhaust castings have a...

    Mecury BlackMax 175Hp, Constant Beep and Overheating

    Did you replace the thermostats? Rebuild the poppit valve? A hot telltale is a sign on a lot of motors, that the thermostats are not working properly, or the cooling passages have a blockage.

    Oil coming out of carburetor

    I looked up the parts list for a random Merc 4 cycle 15HP motor. It looks like the fuel pump is mechanically driven, by the cam or crankshaft. If the fuel pump diaphragm has a hole in it, gasoline could get into the crankcase, overfilling it and forcing oil into the carb via the PCV system...

    Oil coming out of carburetor

    Check your oil level. It is likely overfilled or the PCV system is having issues.

    Bone headed move - put the plug in with 3M 4200

    Hand tight may loosen, and that would be bad. Put some anti-seize on it and moderately tighten with a small wrench.

    Tower of Power 1150 - unknown year - side bowl carbs float-needle valve issue?

    I remember that the carbs are a tight fit. I usually took them off as a unit, leaving them connected by the black plastic "straw" that operates the throttle plate. BTW- those straws are fragile and are not widely available. Crowleymarine says then can get 'em. The top carb is unique because...

    Tower of Power 1150 - unknown year - side bowl carbs float-needle valve issue?

    No rejetting necessary. Actually, I had that exact motor and never had any issue with the backdrag feature. Just to be clear, the backdrag function routes carb vacuum into float bowl, pulling in outside air. The backdrag jet is a restriction for air entering the bowl, thus creating a small...

    Tower of Power 1150 - unknown year - side bowl carbs float-needle valve issue?

    The cowling is from 1977. Not the first year for PTT. Serial number should be between transom clamp screws. Rebuild the top carb with new float inlet needle and seat and gaskets. If you see any dirt, get it out and rebuild the other two carbs, as well. If serial number is not on transom...

    Suggestions on how to fill my onboard gas tank?

    Jimmbo, You might want to correct your post to say that even idle requires some small amount of oil mixed into the gas for carb 2 cycle motors. If you have evidence of 2 cycle motors with carbs running on straight gasoline, I would like to see it. Modern engines need 50::1 or maybe a bit...

    How to run PTT wiring thru 1998 OMC control handle.

    The red locking lever on my 1998 OMC concealed mount control handle fell apart after all these years of sun exposure. I purchased a new one, but am having trouble finding the correct path to route the PTT wiring from the thumbswitch in the handle past the locking lever to the handle base...

    1989 Mercury 200 Black Max Maintenance

    You can use any TCW-III 2 cycle oil. Some have found that Seafoam mixed into the fuel helps clean up the carbs a bit. I would not expect miracles. Make sure the overheat alarm works. Rebuild the waterpump with a new impeller, wearplate and 2 gaskets. If the pump cover SS liner is...

    Power trim Wire, 2 or 3?

    Gee, the PTT trim unit has 6 heavy stainless bolts holding it to the transom bracket. I do not think it needs a ground wire. A lot of Mercs did not have trim senders, but if you have one, you should see the body of it inside the transom bracket, and it will move with the trim of the motor...

    Suggestions on how to fill my onboard gas tank?

    Gee, I cannot read all the posts. Likely some have been duplicated. It is real simple. Mix the fuel every 6 or 12 gallons. So get some pint or quart containers. Dump in a pint of oil, fill with 6 gal of gasoline, repeat with gasoline, and oil. when you think you are close to full, do 8 oz...
