    2018 V6 200 J Oil pressure dropping and alarm

    Your engine has the oil pressure sender mounted on the front top of the engine, just a little starboard of centerline. This is NOT a 4.3L engine that some of the people giving you advice seem to think it is. This engine has variable valve timing and high pressure direct fuel injection. Oil is...

    Replacing alternator belt

    No. Yes the engine moved. Yes the engine was moved back to within a few thousands. Nothing changed enough to justify the cost of an alignment check.

    I had this tool at one of the shops I worked at, used it once. Waste of time. As you turn the eccentric piston you will notice it moves in and out as you shift from forward-neutral-reverse. When it's at the most in (half way between forward or reverse and neutral) that's were to do the shimming...

    Volvo Penta 280 Drive Shaft Nut Clearance

    I'm not sure what you have going on, but here are a few things I've learned at Volvo school and doing this job many times. It's pretty rare the shims you install per the calculations are what you end up with after backlash and gear patterning. Backlash and patterning are not optional, they...

    Volvo Penta 280 Drive Shaft Nut Clearance

    They gave you good advice on replacing that brass washer and the keepers. My guess on why you lost clearance, the brass washer was starting to bend. This allows too much clearance at the nut and will keep getting worse until the brass washer lets good and the shaft will come shooting out the top...

    ECM for 1999 Mercruiser MCM 5.0L EFI / 305 CID

    Mercury Marine EPC (electronic parts catalog) shows this engine to have MEFI3 but it could have been updated to MEFI4 because MEFI3 has been NLA (no longer available) for a long time, MEFI4 is also NLA for many years. Here is how you tell what you have. Here's a picture of the MEFI4 conversion...

    Volvo Penta 5.7 no spark

    Good that the problem got sorted out! Thanks for the update. Now I recommend that you repair the wiring to the key switch, The screws that you used won't stay tight ---- the thread pitch is too wide ----- When those wires get loose you risk voltage drops and spikes. This is the main killer of...

    The blocking diode would also need to be shorted then yes.

    Unknown Short Circuit

    That's the blocking diode. If the diode is shorted internally, the engine will continue to run after the key is turned off. If this condition is found, removing the diode from its connector will shut the engine off. If the diode is open internally, the TKS module will not have positive current...

    Volvo Penta 5.7 no spark

    Every Volvo dealer I've worked for has been willing to print a copy for someone who walks through our door. None of them would be willing to transmit it electronically. we sign an agreement to not do that. I'm guessing if you ordered the manuals from Volvo they would include a copy. Might want...
