    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...

    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?

    Swapping 88' 454 Truck Engine to Replace 93' Mercruiser 454

    After multiple issues with the engine in my boat I've decided to just swap the block and heads out. My neighbor just happened to have an 88' 454 motor (Gen IV?) from a suburban with 100k miles sitting around so I got that from him and stripped it down. I know I have to move the accessory...

    Water leaking from block but pressure tested fine?

    I just put new head gaskets on both sides, but even if it was the head gasket, would I not hear air coming out when pressurized?

    Water leaking from block but pressure tested fine?

    I tried looking around but if it was coming from the exhaust manifolds and pooling wouldn't I see a rust line coming from the leak or at least some type of residue?

    Water leaking from block but pressure tested fine?

    Yea, I pulled the drain plug on both sides then put one back in and hooked the leak down tester to the other hole.

    Water leaking from block but pressure tested fine?

    This has got me really confused, Mercruiser 7.4 Gen V I was looking and saw some water dripping from the side of the block, naturally I would think cracked block but just did a pressure test and the cooling system holds pressure fine and I don't hear any air coming out?? I looped the two exhaust...

    What are the 2 sensor on the thermostat housing?

    I'm thinking it must the sensor, I got a new one I can put in just waiting for PB blaster to loosen it up a bit, it's stuck on there tight. I switched the gauge out with the new gauge and it's also reading high so it must be the resistance reading is wrong from the sensor.
