    2002 Volvo Penta 5.0 idles great then dies in gear

    The water separtor will catch most stuff (I always check the screen in my Quadrajet but it is always pristine) but you never know esp if you get water in the fuel. Other things are the anti siphon valve on the tank and some tanks have a screen at the bottom of the pick up tube that can get...

    1986 Mercruiser V-8 5.7L - overheating issue??

    Another not real common cause is leaking head gaskets putting combustion gas into the cooling water. Worth checking for this if other causes don’t pan out.

    1986 Mercruiser V-8 5.7L - overheating issue??

    Yep I said that up above, Merc has a spec for how much it should pump in X amount of time.

    Boat refueling

    If you have a slip and a dock a gas caddy with wheels can work well. We have one we use at home if there is a power outage to fuel the generator. Also as far as gas cans the only ones I’d use today are the SK Racing cans with vents and the optional long spout. These are expensive but are 10...

    1994 OMC Cobra 5.8 only 75% power

    That was a Volvo Penta service bulletin, and they advised removing them, but OMC did not. I have had the flappers on mine all this time (owned it 19 years) and the only time I had an issue was after a bad overheat, so I replaced both of them. I'm not sure that I agree with V/P, and I would...

    Looking for bare engine block with pistons

    Look up Northport Bay Long Island, that's the nearest official body of water, followed by Huntington Bay and then Long Island Sound. My brother just bought a house nearby and will have a boat too, so we can meet in the middle in Huntington Bay. It is a very nice boating area. When I was a bit...

    2002 Volvo Penta 5.0 idles great then dies in gear

    And a 19 year old anti siphon valve on the 19 year old tank that should be replaced, as a matter of course.

    2002 Volvo Penta 5.0 idles great then dies in gear

    The point was that’s what leads up to fuel pump problems....fuel system restrictions that may still exist! And if not corrected will cause the same problem in the future...

    2002 Volvo Penta 5.0 idles great then dies in gear

    The basic problem with using an electric pump is that it must pull from the tank not push from the tank as in automotive applications. This I believe is due to CG regs regarding electric fuel pumps. So any restriction on the suction side can cause problems. The pump will begin to strain and...

    2002 Volvo Penta 5.0 idles great then dies in gear

    I think you know the answer to that question Bruce but you must admit you see many posts on boating bulletin boards of problems with V/P electric fuel pumps (paint flakes clogging the pump, terminals on the relays overheating). The guy at cavemanmechanic.com makes a nice living off these...

    1995 OMC Cobra 5.8L overheating issues

    If the power package is really a ‘95 then it would have the impeller mounted on the engine like a Volvo in addition to the typical automotive style (but marine version) circulation pump. The older OMC Cobras (1986-1993) had the impeller in the outdrive like mine. If it’s overheating that fast...

    Looking for bare engine block with pistons

    Yep that was warming up. 1200 rpm, I set the slow idle in the water at about 600 rpm to account for the back pressure of the water. Best part is that I taught my son how to back up the trailer he’s getting really good at it lol. Weather here is changeable might get a little from a tropical...

    Screeching/grinding sound from carburetor?

    Which water pump, the impeller (rubber) or the circulating pump (automotive style for marine use). When the bearings in those fail they can make noise like that. Also check the alternator and the p/s pump if it has p/s. Same for any idler pulley or tensioner pulley. All have sealed bearings that...

    2002 Volvo Penta 5.0 idles great then dies in gear

    I think that some years of Volvos had trouble with the terminals on the relay for the fuel pump; there is also the oil pressure safety switch that cuts electric power to the pump if the engine stalls to prevent the electric pump from flooding the carb.

    Volvo exhaust bellow blew

    I’m wondering if your exhaust is clogging on one side and all the water is going to the other side. This could cause the side without water to really overheat and cause damage. I’d probably want to inspect the exhaust manifolds and elbows at this point especially if they are original.

    2002 Volvo Penta 5.0 idles great then dies in gear

    There are a number of common problems that can cause that difficulty: Blocked fuel tank vent Corroded sticking anti siphon valve on the gas tank Corrosion at terminals & relays for the electric fuel pump It takes very little fuel for the engine to start idle or even rev in neutral but under load...
