    2008 Volvo Penta 5.0GL Carb Problems

    Any suggestions how to get these tamper proof covers off the A/F screws? I tried drilling and I don't know what it's made of but I can't drill through it, I tried using a small chisel to cut a slit in the side but this is one tough cover.

    2008 Volvo Penta 5.0GL Carb Problems

    O I thought the accelerator nozzle is the u shaped metal piece, I did unscrew the big phillips in the middle where the fuel comes out from the accelerator pump and did clean that out.

    2008 Volvo Penta 5.0GL Carb Problems

    Ok, I'll get a new power valve, would that cause it not to idle at all? I wasn't able to get a fishing line through the air bleeds but let it sit in carb cleaner then blew it out with 175 psi and now I can see through the hole pretty well. The welsh plugs you're talking about are the plugs...

    2008 Volvo Penta 5.0GL Carb Problems

    I took the carb off again and took some pictures, the idle air corrector was definitely clogged on one side, cleaned that with carb cleaner and blew through with compressed air, tried to get a fishing line through it but couldn't get it through. I also found the idle jets on the other side of...

    2008 Volvo Penta 5.0GL Carb Problems

    How do I know if the power valve is blown? It seems to work fine, I'll post detailed pictures of all the parts of the carb later today but it seems to spring open and close just fine. Looking at the diagram it seems the idle jet is hidden behind the main jet and not removable? Where is the...

    2008 Volvo Penta 5.0GL Carb Problems

    Yes the boat is level, I do see the cover, it seems to be a brass cover, it's pretty in there that I can't pry it off with a screwdriver, any suggestions how to remove it? Maybe drill a small hole and pry it off with a pick tool?

    2008 Volvo Penta 5.0GL Carb Problems

    Hey all, I'm working on my 2008 Starcraft with a Volvo Penta 5.0GL with the 2 barrel holley carb. When I got it it had some issues running, when I looked down the carbs I saw one side was dripping fuel fine while the other was only letting out a few drops, so I figured a carb rebuild was in...

    Volvo Penta SX Trim Motor Part Number

    Anyone know where the part number for the trim motor for the volvo penta SX outdrive? I've disassembled my pump assembly and found the motor to actually be surprisingly working, but very rusted from water intrusion. I'm looking for just the motor itself and not the whole assembly which is quite...

    1998 Mercury 150 EFI Flooding Out

    Found the problem, the fuel inlet to the rail was broken and not sealing properly and causing fuel to just spray into the manifold and fall to the bottom where it was sucked into cylinder 6.

    1998 Mercury 150 EFI Flooding Out

    Opened up the cover to see the injectors and noticed injector 6 has the wiring o-ring popped out. And on a side note, I don't know what idiot engineer decided to mount the fuel rail from the back side instead of the front, so to remove the fuel rail I have to remove the entire manifold just to...

    1998 Mercury 150 EFI Flooding Out

    It's not coming out of the overflow from the VST, it's coming out the hose that connects to the VST, I also did some more testing to see if all the cylinders were flooding or just some, seems it's just cylinder 6, I'm not sure if that's because it's the lowest cylinder causing all the fuel to...

    1998 Mercury 150 EFI Flooding Out

    In the diagram, should line e to the upper manifold lower fitting have fuel shooting out of it when cranking over? I had disconnected that line originally to see if the VST was overfilling but to my surprise the hose was shooting fuel out when cranking over, not running, just cranking, no...

    1998 Mercury 150 EFI Flooding Out

    I do have an understanding of electronic component testing with a good voltmeter, I'm an inboard Mercruiser tech with 7 years of experience, I'm just not too familiar with these old EFI 2 stroke outboards and I just didn't want to spend $80 on a manual if this was just a simple problem, it's a...

    Do you know where the TPS is on this motor and how to test if it's stuck in WOT?

    1998 Mercury 150 EFI Flooding Out

    Hey all, i'm working on a 1998 Mercury 150 EFI and the issue is it keeps flooding out, I can get it started by holding the throttle all the way down but if I let off it'll immediately die. At first I thought it was too much oil mixing into the gas as I saw a lot of blue smoke, but I completely...

    2004 Mercruiser 3.0 Water/Oil Mix Coming Out of Breather

    I did look all around the block and didn't see any cracks or rust spots from water dripping, outside of the block was extremely clean, I also checked again after having the issues but no sign of any external crack so I guess it must be internal somewhere, I get internal crack causing water to...

    2004 Mercruiser 3.0 Water/Oil Mix Coming Out of Breather

    I did a search and found some similar threads but no real answer to my issue. I have a 2004 Mercruiser 3.0 with unknown history, supposedly the boat was winterized but I'm not sure if it was done properly. When I got the boat, the oil looked good and compression test was good, on the first trip...

    Will Optimax/EFI lower unit work on a 225 Offshore?

    I just recently bought a boat with a Mercury 225 offshore motor on it, the previous owner said it needed the lower unit replaced, can I use a lower unit from a optimax or EFI 225?
