    Removing impeller

    I think you might be seeing that this tool comes as part of an D3 maintenance kit. If you look at the kit contents, I'm guessing you will find a different impeller in the kit. Diesel engines usually use bigger impellers like the ones in the videos you posted. But the part number I posted is from...

    PCV Question

    You only use a PCV if the hose goes to manifold vacuum. If the hose goes where you have it, it should have an dummy fitting in the valve cover.

    Bellows Adhesive application

    Interesting, I don’t think I’ve ever seen adhesive recommend for MerCruiser exhaust tubes. What manual did you read that in?

    how to remove prop shaft seal on a duoprop DPS-A ?

    I think it probably is more expensive to make it this way. Those lips are there to function as a fishing line cutter. Actually seems to work pretty good. The DPS series drives are very different from the DP series drives. Very few parts interchange. The DPS series (depending on serial number...

    how to remove prop shaft seal on a duoprop DPS-A ?

    I'm guessing you worked on a DP-S ? They have prop seals like the MerCruiser. And those seals can be removed from the rear. But the O.P. posted pictures of a DPS-A bearing carrier. Those seals can only be pushed out the front and the needle bearing will come out with them. The O.D. of the seals...

    how to remove prop shaft seal on a duoprop DPS-A ?

    @alldodge @Scott Danforth I just got to ask. How many times have you done this job on a DPS-A? That’s a $300.00 bearing carrier that is about to get destroyed.

    Kill Cord does not operate properly (not electtical)

    This might be a boatbuilder issue. Some of them supply the control. Either way. This is something any good selling dealer will take care of ASAP Might be time to raise your voice a little bit.

    how to remove prop shaft seal on a duoprop DPS-A ?

    Not that I know of legally. But if you search, maybe you can find somewhere to steal it. Maybe get a virus at the same time?

    Starter spontaneously starts cranking. Volvo Penta GXi 8.1 L 2008

    on your engine the starter can engage while the engine is running. Also noticed that this engine has never been registered, suggest you contact a Volvo Penta dealer and get it registered in your name.

    Fuel consumption

    MerCruiser, I think. It was soo long ago I’m not 100% sure. Whoever came up with this didn’t think it through. Fuel comes into the filter at the top, fuel leaves the filter at the top. Oil is heavier then gas. The fuel flow thru the filter at 1500rpm is very little compared to its capacity so...

    Fuel consumption

    Only people who are looking to "cut corners" do this. One of the manufacturers recommended this for one year. They changed it pretty quick. Because it's not enough.

    Starter spontaneously starts cranking. Volvo Penta GXi 8.1 L 2008

    You didn’t post a serial number so I can’t tell you if the starter can engage while the engine is running. I would test the dash switch.

    Bravo 3 Sea Water Pump - What's this?

    The fitting in the picture is a quick disconnect. MerCruiser added it to make it easier for boat builders to install the engine, but it makes it harder to do anything else. How it works is covered in the service manual and a service bulletin. I recommend you not disconnect it, they are very hard...
