    Volvo Penta 5.7 Fuel Starvation Under Load

    Please start at the beginning with a more compete story. Example: new to you boat? Year and serial no. of engine? Has it ever run properly? What maintenance has been done and did that precipitate the issue? Please be as informative as you can. Fuel pressure holding is a good sign but the fuel...

    Water pump leak?

    Waterman, Pulling the heads will only get you so far unless there is obvious visual damage in the block. I cannot stress enough that water in cylinders can do great harm > easily destroy a motor with one stoke of a cylinder. Since you have that handy neighbor, I continue to recommend get ALL the...

    New engine installation

    Ok so that is normal. While cranking the engine the coil will “fire” (spark) by design. Without the high-tension wire to the distributor that spark has to go somewhere so its going everywhere. Continued doing this will start to break down the insulating properties of the coil casing. If you...

    New engine installation

    Please explain “sparking” more. Ie, were you seeing lightning like sprigs of sparking fm the tower of the coil? Was the high tension lead from the coil to the distributor connected or was it naked like in your picture. Or you were seeing heating up and short like sparking coming from the coil’s...

    Stalling, sudden low idle.

    Survivor, if you are not familiar > the reason for targeting the tachometer is that its ultimately hooked into the negative side (triggering side) of the coil. If the tach is shorting out intermittently it could easily cause the coil to not spark intermittently. By removing it from the ign...

    Water pump leak?

    Waterman, sorry for delay in getting back to you. Were you able to run the compression test / leak down prior after pulling the manifolds and clearing the water out of the cylinders (crank engine over without plugs)? Recall this will be the telltale of how far one must go or at least provide an...

    George, The increase of pressure is a positive sign, and I am keeping my fingers crossed that all will be good. Its unfortunate will need to wait until next season, and I really am looking forward to that on the water test. On another note: George you get my personal “Original Poster of the...

    Engine wouldn't fire without throttle after overnight

    My intent was to highlight a previous answer to the question about 8 years, but I will also offer my thoughts on the issue you are experiencing. This is how I view the world of motors: an internal combustion engine is a marvel of engineering and is akin to a well-rehearsed and tuned orchestra...

    1981 MerCruiser 120 tick/ squeak

    Oh boy. Excessive blowby is a sign of piston rings not sealing. My new suggestion is to also do a (warm) compression test and post results.

    1981 MerCruiser 120 tick/ squeak

    There is a method to adjust without the engine running. Most of what you will read is about getting to zero lash by spinning the pushrod. However, one of the things I have learned from this forum is that its best to set the zero lash by trying to push up and down on the pushrod > a true zero...

    1981 MerCruiser 120 tick/ squeak

    Couple of thoughts: Read up on how to adjust these valves. Concern is that you can overtighten and bottom out a hydraulic lifter. So, as you are adjusting the noisy one, if you continue to crank down on it and still noisy its more than likely a failed lifter due to running it on low oil. As to...

    When you get your new Moeller pickup tube it will not come with a screen, as they stopped doing that. At least that is what the Moeller rep told me back in 2015. Also you will need to cut the tube, instructions should be included.

    Water pump leak?

    So much for the good clean life. At least you and your neighbor are going to have a fun project this winter. My suggestions are: Pull off the heads now and see how extensive the damage is. Perhaps damage just in the top end (not the block / pistons). The risk here is running out of time and if...

    Geroge, My apologies, I should have been clearer about what to look for re: fuel pressure under load. If you can run the boat on the water, with another person on board, record the fuel pressure at all speeds up to and including when it starts to bog down. So run at idle (in gear) for two...

    Water pump leak?

    The reason it would not turn over is because of “hydrolock”. Google it for more info but it comes down to water is not compressible > you had that cylinder filled with water and as it came up on its compression stroke, the water cannot compress and thus it stopped turning. Given this was done by...
