    Prop / prop shaft damage

    Thank you. Not only was it bone dry, I could hear the hiss of the air rushing in as I was opening the hexagonal bolt of the dipstick. I will next check the drainplugs for any residue/metal shavings. The boat was serviced in April, and I paid for Gearcase oil, gearcase O ring, and O ring top...

    Prop / prop shaft damage

    Removed spark plugs. All four dry. Tried turning the engine at the front, where the belts are, I can turn it over manually, quite hard but turns over.

    Prop / prop shaft damage

    Hi, I had an unfortunate series of what I thought small incidents recently. 5.2 m Glastron MX175 runabout, with VP sterndrive. 1. Upon returning home with my boat and parking it, I manually pushed the trailer to back it up in my driveway and hit and scraped my timber fence with my...

    Alternator and fuel pump on Volvo Penta 3.0 GLP-D

    Just a belated update to this issue. My fuel pump is mechanical, not electrical, so anything I describe above is largely irrelevant to the issue. I was with a faulty fuel gauge and an empty tank.

    Oil pressure switch / oil pressure sender

    Time for humble pie. I can see the experienced people starting to smile. ... I've been deceived by a faulty fuel gauge/sender/float. That's for another day. I ran out of fuel. My gauge was on the half mark, with an empty tank. Would never go below half, I always thought I'm safe with half a...

    Oil pressure switch / oil pressure sender

    The mystery deepens. After 5 days of investigations (and no intended fix!) my fuel pump works and engine runs. I've decided this morning to get a simple vacuum gauge and have some numbers on the vacuum this fuel pump creates, and not just a finger test, before I remove the pump and buy a new...

    Oil pressure switch / oil pressure sender

    An update on diagnosing this above issue. It certainly looks like the mechanical fuel pump. 1. Removed hose from pickup/anti-syphon valve from top of tank. Connected a clear hose, and checked for blockage here by slowly pumping/sucking up fuel. Fuel rises quite easily; there seems to be no...

    Oil pressure switch / oil pressure sender

    Thank you, great help! I'll start tomorrow by adding another 20 liters of fuel...gauge shows half, but who knows? Only got the boat a few months ago, and always kept fuel above the half mark, where it currently sits. The gauges are quite old, most of them behave, except the RPM that occasionally...

    Oil pressure switch / oil pressure sender

    Thank you. Another couple of images of the engine attached. Yes, that's the only place I have hose/tube coming from to the carburetor. Since I have no fuel reaching the carburetor upon manual priming (with the throttle control or right on the carburetor), I'll have to investigate anti syphon...

    Oil pressure switch / oil pressure sender

    Thank you. That indeed stopped the alarm, and I can now listen when I turn key from OFF to ON. I can hear a single faint click from around the fuel pump every time I turn key to ON, no humming, no turning noise. I suppose I should hear a humming of the pump. If my engine has an electrical fuel...

    Oil pressure switch / oil pressure sender

    Thanks everyone. It looks like this time I might have a carburetor issue. While previous shutoffs were all sudden and clean, no spluttering, the latest no-start had a little splutter and running for a second or two while key on start. Looking down my carburetor throat and advancing the priming...

    Oil pressure switch / oil pressure sender

    Hi all, I am investigating previous sudden and clean shutoffs of my VP 3.0 GLP engine. Initially, I suspected fuel pump being shut down by a struggling alternator and a potentially failing bilge blower, this latter knocking down both dashboard and multimeter voltage reading from 14V to 12V while...

    Alternator and fuel pump on Volvo Penta 3.0 GLP-D

    Apologies, my actual numbers are closer to the ones you mention, yes. Resting battery - it has taken a battering after all the trials and haven't been recharged yet - 12.4 V On alternator - idling only, ~800 RPM, on garden hose - 14.2 V The internal resistance of my bilge blower is 0.6 Ohms...

    Alternator and fuel pump on Volvo Penta 3.0 GLP-D

    Should read flinches slightly at the trim, 0.5 V, but comes back.

    Alternator and fuel pump on Volvo Penta 3.0 GLP-D

    Hi all, thank you everyone for your advice. Everyone's suggestions was acted upon, and investigated, (Lou C, alldodge, MarineSp, Grub54891), and all this helped in what it seems is isolating the issue. The culprit seems to be the blower, or some other component on the same circuit. Blower...
