    water in all 4 cylinders

    well, we have a verdict.... its coming in through the exhaust..... pulled the upper intake, and there are signs of water in the past, but no standing water in the intake side of the house. Exhaust side is different.... pulled the elbow, and there was water up to the port level in the manifold...

    water in all 4 cylinders

    Ill get the manifold pulled here today and start checking it. What is a good way to seal the engine to test it. This is an open system, so there is no radiator cap to hook the tester to. My guess is to seal off the port going to the manifold, and hope for the best? I got to find my...

    water in all 4 cylinders

    Engine is a 1980 "ish" vintage Mercruiser 120 S/N 5612859. During testing for re-commissioning, I am running on hose water hooked direct to the inlet hose (no drive installed). Engine runs good, but am getting milkshake in the crankcase, and when I pulled the plugs this morning, and cranked it...

    this refers to the 4150 series as used on other Mercruiser engines. the 4150 is a mechanical secondary double pumper that was used on the larger 440/460 Cyclone and 475 Turbo engines. Its the only reference to a Holley carb that shows up in the service manual. Not quite what you are looking for...

    should not be. Just need to find one that is "marine rated". IIRC Holley has a few that were used on the Mercruiser line, and IIRC one of them was vacuum secondary. Ill dig through the manual and see what I can come up with for you digging through the manual got me zip.... here is a page from...

    the secondaries are mechanical, the air valves at the top of the bore open in response to airflow. When these open, it raises the metering rods as well for more fuel.

    Mercruiser 3.0 diagnosis / serial number decode

    if it has a GM derived carburetor, there is one in the inlet. You have the fitting from the pump that screws into a larger "hex" type thingy. Unscrew the larger hex piece and the filter resides in there with a spring. Beware of the spring.....

    Mercruiser 3.0 diagnosis / serial number decode

    the neutral cutout grounds the coil when switching gears to allow the gears to unload the shifting dog clutches. If this were inoperable during shifting, it would be much harder to shift out of gear. If this is not working properly, disconnect it (troubleshooting only) and verify that the engine...

    ok, your serial number is on the sticker in the "middle" picture. check the tune up page that I posted last night, your serial number is in the range specified. if you need more info on the carb, its in Mercruiser Manual #3. If you need info out of the manual, let me know, Ill see what I can do...

    bingo, if the coil isnt being triggered, then it will not work. In your case, make sure the points are clean, and check the dwell. when this checks out, you should have spark

    Mercruiser 3.0 diagnosis / serial number decode

    the coil produces the spark, which then goes to the distributor rotor, and out through the side terminals, wires and to the plugs. What you have is the points (also inside the distributor) that doesnt seem to be opening which causes the magnetic field inside the coil to collapse creating that...

    Mercruiser 3.0 diagnosis / serial number decode

    the coil needs a switch in order to fire. This is the points. If the coil has 12v and ground, but the points arent working, then you no get spark. either the coil is wired wrong, or the points arent doing their job

    Anyone Seen these?

    have you noticed that YOU are the only one here that is defending this prop, regardless of the questions brought up about it. Have YOU noticed that there is only ONE site doing videos and/or testing of this prop? Have YOU considered that there may be a reason for this?? as for what data I would...

    Anyone Seen these?

    yep, its original technology, and with that come questions that either are being avoided or not answered with the testing that has been shown. I think a lot more would be accepting of this prop if there were a true apples to apples comparison with another known technology. Say a SAME PITCH/SAME...
