    Best Alternator?

    I have a 2006 Cobalt with a Volvo penta 5.0 GXi-G. One of the diodes failed in my alternator. I bought a used one on ebay and got a repair kit for the original and repaired it as my spare. A photo of the original alternator with the VP label is below.

    2002 Volvo Penta SX outdrive trim/tilt problem

    When you say zero issues on the water do you mean the trim worked both up and down? See this thread on a similar problem to yours. It may have some things to check. https://forums.iboats.com/threads/volvo-penta-trim-wont-go-down.384519/ If the pump motor is running but the outdrive does not...

    I salvaged this 100’ jet drive houseboat and I need help!

    FYI This appears to be a Volvo Penta K25 jet drive. Workshop Manual and an installation manual are on ebay or you can buy from Volvo Penta. Engine manuals are also available. that should help. I would get the hull number and try to figure out who made the houseboat. Many but not all houseboat...

    I salvaged this 100’ jet drive houseboat and I need help!

    As to 5., I have had a couple houseboats and they had ZF Mathers MicroCommander controls. In fact virtually all houseboats on my lake had MicroCommanders. However I had Mercruiser drives, not jet drives. I would guess that MicroCommander controls could be used for jet drives also. You might...

    Oil level too high?

    I think it is normal to leave around 1/2 quart in the pan when pumping the oil out, more if not level. Some Oil in the filter too. Now that you have confidence in the dipstick level just add oil until at the full mark. One thing you might consider if you trailer your boat is to buy an oil...

    Shocking experience

    If there is leakage from the shore power into the water near the boat, the outdrive is in the water so anything connected to the outdrive, an ungrounded gimbal housing, could have that voltage waiting for a path to ground. You could receive a shock if you touch the gimbal housing (if unbonded...

    Shocking experience

    To get a shock you must touch two conductors, normally metal, that are at different voltage levels, whether AC or DC. What else are you touching besides the gimbal housing when you get this tingling? Is it the engine? Do you feel the tingling if the AC power is not connected? You determined...

    Shocking experience

    I would do this: Use a voltmeter and measure the voltage on the gimbal to ground. Is it 12 volts or some other voltage. If 12 volts you have a misconnection or fault of a hot lead. Check to see that the engine block and drive unit are grounded properly to the negative terminal. Start pulling...

    Removing impeller

    I plan to use a 3/4-16 bolt to remove my impeller this spring. Maybe I am missing something but why cant you just thread the bolt into the impeller hub until it contacts the pump shaft and by threading the 3/4” bolt further break the impeller free. I think it should work the same as what you...

    VP Fuel Cooler needle valve/hose to intake

    Take a look at this youtube video in which the needle valve in the VP fuel pump is explained and tested. This guy (mancavemechanic.com) has other videos about the fuel pump and the issue of paint flakes clogging up the system at the pressure regulator.

    2007 Gxi-G 5.0 Rough Idle Issue

    Just my theory. I dont think the fuel is being dumped into the throttle body. If the float and needle valve in the fuel cell reservoir are stuck, fuel from the fuel regulator fills the return hose. When that happens, the regulator cant bleed off excess fuel to control the pressure. At less than...

    2007 Gxi-G 5.0 Rough Idle Issue

    I think what he is describing is the float and needle valve at the top of the Volvo fuel pump cell reservoir between the low pressure pump and before the high pressure pump. It functions like a check valve and prevents the fuel being pumped into the reservoir by the low pressure pump from...

    Replacing Trim Pump on DPS-A Drive

    Duoprop DPS-A Drive pn 3883609 My current pump runs but does not raise or lower drive. It was a little low on fluid so I added about 2-3 oz. to top off. No different. I have tried to run both directions to bleed but no change in sound or operation. So I have a new VP pump to install. There us...
