    2001 Glastron SX195 5.0L Volvo Penta SX Vibration when turning

    Does it make a growling noise when turning? Vibrations and noise in a turn usually point to the Gimbal Bearing and they can "feel" just fine. Tuff call when everything looks good. I would put a grease gun to it and see if it's better when filled up.

    Reverse issue

    As you describe stalling when you put it in gear, that sounds to me that the prop could have been caught in something like a piece of rope in the water. If bound up tight, it could cause great difficulty getting it out of gear like you mentioned. Going the opposite way when putting in forward...

    White Smoke/High Idle

    So your boat if a GXI is fuel injected and if it's white smoke and not steam I would say your burning a little rich. The idle issue you speak of, I would first have a look at your Idle Air Control Valve (IAC). It's attached with two small screw to your throttle body along with your throttle...

    2002 Volvo Penta 5.0 idles great then dies in gear

    What about the in-line screen just inside the carb at the inlet? Folks change their fuel water separators' often enough but the inlet screen can get neglected and I've seen them cause the issue you describe more than once.

    PSA, 'Volvo Penta Fuel Pump Rebuild

    The picture you show of the fuel pressure regulator screen with all the paint on it is why I keep mine on and have never replaced it with the clip. When the pump whine gets louder, it's very easy to remove the regulator and check that screen. If it has a bit of paint scum, I then pull the high...

    Volvo 5.0 glx surging issue

    Sounds like a bad low pressure / boost fuel pump .. Says above that you replaced the high pressure pump. A bad boost pump, the boat will start and run, but when you take off it will quickly become fuel starved. Just a thought.

    Slow to plane, great top speed?

    The 3.0 of course is no power house and lacks torque which will be amplified even more when over propped a bit. You are in the low end of the RPM band, but as mentioned earlier, a 21 will do you better, get you to the high end of the RPM band and you'll notice the boat getting on plane quicker.

    Volvo Penta 5.7 alarm at high speed

    175 is the engine temp. I would shoot the exhaust manifold and the top of the Cat/Riser. They should be warm but not hot enough to grill a sandwich.

    1998 4.3L GL Fuel Pump Issues

    Did the boat sit for a very long period of time? There is a antisiphon valve that the fuel line connects to at the tank and it could be stuck in the closed position. Also if any wiring has been messed with and the wires to the pump are swapped, it could run backwards and yes, the pump itself...

    Volvo Penta 5.7 alarm at high speed

    How hot is the exhaust getting? For that year of boat, it probably has the catalyst exhaust and the coolant passages are quite small and easily plug up. It is curious that a solid alarm isn't putting it in limp mode.

    5.7 Gxi-f outdrive issue

    Sure sounds like a bad coupler.

    Backfire - intermitting performance

    This is text book of a failure of the low pressure/boost pump. With just the high pressure pump, the engine will start and run and take off strong but will quickly fall on its face. When brought back to idle, the reservoir on the fuel pump will recover but the same thing will happen when you...

    Head gasket? Cracked head?

    Looking at your picture with the wet exhaust in the middle, a bad riser gasket can do the same. you mentioned that antifreeze was still in the manifold and that it was drained prior to refilling so you're probably ok there.

    Head gasket? Cracked head?

    A cracked intake manifold would cause what you're seeing as would a boat left completely open in the elements allowing enough water down the carb into the intake as everything else mentioned (head gaskets cracks in the block/ heads ect. Do you have water in your oil? If this was properly...

    Dreaded Fuel Cell Whine?

    The engine will start and run with a bad low pressure (Boost) pump but will fall on its face when you try to get up on plane. Have you removed the high pressure pump from the cell to check its intake screen? That's the one that will get clogged up from paint ect and will cause pump wine as...

    What´s the best replacement for AQ271C (or 570) 5.7 GM engine, ideally stroker?

    The easiest and most economical will be to replace your current motor with a 5.7 Vortec long block. Not much sense re-working a 30 year old raw water block and adding a new cam and buying a set of vortec heads. You will need a new intake manifold but should be able to use your current carb. You...

    Poor Running - Low WOT

    What prop pitch are you running? Excessive pitch will lower the top RPM but you're at the minimum of the RPM range now but still in spec. Do you know how to properly trim up the drive once you're on plane to achieve max speed and RPM? I ask these questions as you may have NO problem at all and...

    My lower unit drain plug fitting on the drive is stripped out. I have tried a new plug but it doesn't snug up well Im curious if any have removed that piece that the drain plug is in and was it a difficult job?

    Am about due to change my U-joint bellows on my DPS-A outdrive and am having issues with part numbers and what will work. Original was 3841481 then 23075752 ect. My question is will a Sierra 18-2765 work on the newer drives as it did on my previous SX-M drive? Curious if anyone out there has...
