    Overheating after impeller change

    I cannot think of any way to do it without lifting it out. BTW you have to remove the tube to inspect it, as in my case it was not visible until removed. I lost most of a season's boating chasing down the problem, lifted the boat out 3 times, bought new pump etc. Let us know how you get on in...

    Overheating after impeller change

    Mine did this last season, but only overheated at low revs. Anything over 2500rpm would run all day at 160F, at tick over she heated up really rapidly. Turned out to be a hole in the Bronze tube that joins the lower and upper parts of the outdrive, it sits in the exhaust tract. New ones are...

    2000 Volvo Penta 5.7GSi PEFS still running rich!

    I had a running rich problem for a full season, turned out to be a bit of debris holding the thermostat slightly open and causing it to run at 140 F. ECU kept supplying a rich mix.

    Quick check of ground by cleaning an area of the body of the temp sender and a wire from cleaned area to a known good ground. 2 min job to confirm.

    Removing impeller

    Hi Taff Can you edit your post to avoid confusion, I think you meant 3/4" not 3/8" Dia. I would think the small "O" rings should have stayed on the screws, so that they didn't fall out into the bilge.

    Removing impeller

    Hi Taff, As the previous versions of the Volvo pumps were manufactured by Johnson Pumps of Sweden, I would expect them to have supplied your pump too at a guess. Below is a nicked page from Johnson Pumps catalogue which might just be relevant.

    Winterising Q

    1/4" drive socket set, use 5/16"AF or 8mm socket. There is also a slot for a flat blade screwdriver. (I see you have the latest motor which does not have the crankshaft mounted pump, however I would expect the screws are the same)

    Changing water pump on Volvo Penta

    Which water pump, raw water or circulating pump?

    gl5 oil all the same?

    Well so is the price of parts that can get damaged using the wrong oil. Volvo Penta used to recommend using Mobilube 1 75W - 90 SHC for the DP-SM outdrives if you could not get Volvo GL5. Your choice.

    VST question for 5.7L TBI....

    Interesting, I have the 5.0Gi which is plumbed slightly differently, as in the diagram I attached. My VST was also completely blocked at both the inlet & discharge. Mine had corroded though from the water side to the fuel side and required a new body, which at first seemed to be unavailable...

    VST question for 5.7L TBI....

    Having just repaired my VST "cobalt1999" is correct. As you no longer have the raw water thermostat housing you will need to find somewhere to tap into the raw water pump supply that feeds to your heat exchanger and run a small diameter 3/8" ID line to the barb (No.17) that has the yellow plug...

    I need an adapter from No. 4 SAE female to 5/16 32 TPI schrader valve. I want to be able to check the high & low pressures on my 1999 Volvo Penta 5.0 Gi. There is a Schrader Valve on the Vapor Separator Tank for the low pressure and the same fitting on the HP line to the TBI. This must be a...
