    Water on top of Intake Manifold

    While water can drip down from the engine cover on to any part of the engine; if the gasket doesn’t seal or the bolts not torqued 100% you will see a leak on one of the 4 corners of the intake. Remember the rear ones are closed in the intake but open on the cyl heads. Front is open on both...

    Winter storage cover

    I cover my bow rider from bow to stern with a custom Taylor Made cover & I built a support frame to keep it from caving in. I don’t shrink it because it’s painted in red Imron. This has worked well here in Long Island for 20 winters. With covers it’s always the support system if you get snow...

    Dealing with bogging for too long and need help because I've done just about everything!

    A defective knock sensor made our 98 Subaru run like it had no power; I changed that and the speed sensor twice in the time we owned it (18 years). However these faults always set an easily read check engine code; not sure if marine engine management systems do the same thing.

    Water in the intake

    When I had my head gasket failure the water was in the oil/engine for about a week before I could get the boat off the mooring, though I did drain it out before I hauled it in. After I got it back on land I changed the oil 3 times and drained the engine after each time it was run. When I pulled...

    Water in the intake

    well in that case, we can't say for sure if the water came from a bad gasket between the manifold and the elbow. Was there obvious rust in that exhaust gas passage meaning that water has been in there for a while?

    2004 Volvo Penta SX-M1 Outdrive Cracked Bellows.

    Do it now you don’t want the drive shaft to corrode to the gimble bearing making the drive nearly impossible to remove. A rule of thumb with I/Os that I have learned is putting off needed repairs is a fools errand. It ALWAYS comes back to make the repair more difficult & expensive. And yes you...

    Water on top of Intake Manifold

    Those manifold bolts thread right into the cyl head but not sure of any thread into a water passage. Thinking back I had the same issue…I had to remove that engine lift bracket that some OMCs and Volvos had using the last 2 Intake bolts on the port side. I had tried a Holley carb instead of the...

    Water on top of Intake Manifold

    That appears to be right by the water passage part of the gasket. Even though the only place the water flows thru the intake from the heads is in the front, those passages are there in the heads because the head is really just one casting the same for the port & starboard sides. That passage is...

    Winter storage cover

    I would not use 2 covers it will trap moisture no matter what you do. Build a support for the storage cockpit cover out of pvc & wood & keep your regular cockpit cover stored for the winter it will last a lot longer that way. That’s what I do with my 20’ bowrider. If you get snow on top of the...

    Volvo Penta 4.3 GL Water In Cylinders After Running

    When the previous owner said, it got a BIT hot, what exactly does that mean? Because overheats on these engines, can result in blown head gaskets and cracked cyl heads. Had both on mine some years back. A worn impeller can cause a mild overheat (180-200) but a shredded one, that could be like...

    Water in the intake

    Ok when you took apart the manifold & elbow did you drain the water out of the manifold first? If so then there should not be any water in the exhaust gas passage at all. However if you took it apart without draining the manifold first water could spill over into the exhaust gas passage even if...

    Water in the intake

    And is that water in the bottom of the exhaust gas passage?

    Could water be getting into the fuel tank vent hose causing a temporary blockage as the boat moves with the waves?

    Water in the intake

    Your Vortec gaskets look fine but I am wondering if you have rust or pitting on the sealing surfaces of the cyl heads and the intake. Any pix of those? I had to spend a lot of time cleaning up the sealing surfaces of my old intake. Actually bought a spare one because mine has been used in salt...

    Vortec engine or not?

    12 or 8 bolts for the intake manifold? 12 = pre Vortec 8 = Vortec Is this a 4.3 V6?

    Popped through the intake.

    Those look good, maybe could go a tad richer, but no sign of water or oil
