    Water in bilge has returned in 1995 Four Winns 190 Horizon

    I would to further investigate: Start with a totally dry bilge, put your cell phone on a selfie stick and have someone slowly back the boat into the water and watch & listen. One problem and it is a significant one, is that I/Os by nature of their design have a lot of places to leak water at the...

    What is normal temperature 3L Volvo Penta?

    It should be a 160 stat. I never had a 3.0 but I have a 4.3 V6 Cobra with the same thermostat housing and exhaust design as the Volvo and it ranges from 160-175. If it is really hitting 180 that is a little too hot. Try taking IR temp gun readings on the stat housing or right where it bolts to...

    Need help diagnosing temperature problem on Volvo Penta 5.0 GL-J

    I think when you have a 160 stat you should see this at idle. Pic was taken in the water after cooling down after coming off plane. Maybe a bit higher but based on my experience (only difference is I have a 4.3 with the Cobra drive mounted impeller, but exact same thermostat housing & exhaust...

    Need help diagnosing temperature problem on Volvo Penta 5.0 GL-J

    In the drive there are 2 water tube grommets that seal the water transfer tube that sends water up from the lower unit to the upper unit. These can deteriorate over time and cause lowered raw water volume as can that plastic fitting in the pivot housing which can crack. However these factors...

    Water in bilge has returned in 1995 Four Winns 190 Horizon

    That model has the raw water pump on the engine not in the drive. You should pull the drive to check the drive shaft bellows for water.

    4.3 over heating at low rpm Help

    When checking your temps with an IR temp gun you’ll find different parts of the ‘stat housing read very differently. On my OMC/Volvo design the top and sides read cooler than actual temp, I find that the location that reads most accurate is the intake manifold right under the stat housing...

    "Premium" vs "high performance" lube

    I’ve used the Merc High Performance on my Cobra because the OMC gear lube was hard to find locally. Been using it 15+ years with excellent results.

    No ground in fuel pump relay socket Volvo Penta 4.3 GXI

    That looks like the throttle body injection system used by GM where there are 2 fuel injectors like a 2 bbl carb. A stopgap system between carbs & port fuel injection.

    2004 Merc TKS intermittently missing, running rich, running on.

    The Mercruiser 4.3s did seem to have a run on (dieseling) issue because I recall seeing a TSB to correct or at least reduce this problem, I don't recall if it was specific to the 2bbl or 4bbl carb though. Interestingly I have never had this problem with my OMC 4.3 4bbl Quadrajet carb version...

    4.3lx flywheel replacement

    Here's a pic of the starter and bolts, see the knurled section, that keeps it from getting loose. Notice how big the old direct drive starter was. They weighed like about 20 lbs, not easy to install holding it up under the engine with one hand and getting the bolts started with the other hand...

    4.3lx flywheel replacement

    I don’t know that there is a published spec per se but here’s what I’d do, use only the ones that come with the new starter or carefully measure the height of the starter mount area. Then thread the bolts into the block and measure the length from the block to the part of the bolt head that...

    4.3lx flywheel replacement

    Check the transom mount/exhaust Y pipe for leaks/corrosion, steering pin/arm and power steering actuator for leaks/bad seals & leaky hydraulic lines. When installing a new starter make sure the bolts are the right length; if they are too long & bottom out before clamping the starter ti the block...
