    Bellows adhesive or not?

    From my VP Workshop Manual AC 2(2) from 2003, on page 43: "Coat the outside surface of the gimbal bearing bore with Volvo Penta Gasket Sealing Compound. Sealer is not required on the outside of the exhaust opening." and page 61: "Apply Volvo Penta Gasket Sealing Compound around the complete...

    Just rebuilt the trim cylinders, now the outdrive won't stay up under load

    My guess: Could be the piston seals in the cylinders or the return valve in the pump, probably the former since everything worked prior to the rebuild. That is assuming you have no leaks externally. There's a guy called Michael Romer on youtube who has some videos on how to test for leaky...

    Seeking advice regarding Volvo Penta 5.7GXi-HF fuel pump whine

    Revisiting an old thread as another season draws to a close. The fuel pump is still whining and still working. I had the idea of unplugging the electrical connectors for the pumps with the engine running in an attempt to determine if it's the low-pressure or high-pressure (or both) which is...

    Engine over heats

    Does your power steering cooler have an extra hose barb blocked off by a rubber cap held on by a hose clamp? Could be a potential for a leak.

    Flushing raw water side of 5.7GXi-HF

    Correct. Do you see any problems with the setup I described in my original posting?

    Flushing raw water side of 5.7GXi-HF

    That is a good suggestion and a good way to descale the heat exchanger and the bottom half of the raw water cooling circuit. However, I wanted to get some circulation on this in order to also clean the passages of the exhaust manifold and risers as well as the fuel cell.

    Flushing raw water side of 5.7GXi-HF

    Raw water cooled with heat exchanger so the block is fresh water cooled.

    Flushing raw water side of 5.7GXi-HF

    Sorry, my mistake, I meant the entire outdrive. There is a threaded fitting on the gimbal housing where the hose feeds raw water through the transom, thought I’d connect my flush hose there.

    Flushing raw water side of 5.7GXi-HF

    It's a descaling agent meant to remove marine growth etc

    Flushing raw water side of 5.7GXi-HF

    Thanks for your input. I would be doing this as a part of winterizing the boat so the lower unit is coming off regardless. This being a freshwater cooled engine, the flushing is for the heat exchanger, exhaust manifolds/risers and fuel pump. Is my concern for the risers unfounded? I would think...

    Flushing raw water side of 5.7GXi-HF

    I want to flush the raw water side of my 2007 5.7GXi-HF with Rydlyme or something similar. The drive is a DP-SM. In order to do this, I had the idea of removing the lower unit, connect one end of a hose to the threaded fitting on the the gimbal housing and the other end to a ciculating pump...
