    Mercruiser 5.0 dies while idling - no fuel from line

    It could also be a clogged screen in the fuel pick up tube; if you replace the anti siphon and still have the same problem,

    Chrysler 318 cooling issues

    If you are in an area where there is marine growth that can cause a blockage in your raw water intakes. Very common here with boats moored in salt water. I usually tilt my outdrive all the way up every couple of weeks to check the water intake holes. Even if the impeller is slightly above the...

    Did you pull the thermostat housing and check for pieces of the old impeller there?

    Trying to get some information

    The Volvo SX was based on the OMC Cobra. It’s nearly the same transom mount but the drive was converted from dog clutch shifting in the lower unit to cone clutch shifting in the upper unit.

    That’s correct if it looks like a Cobra it may be a Volvo SX.

    454 bogging and misfire under load

    PS cold compression tests are not as accurate as hot. Engine should be warmed up all plugs out and throttle & choke valve wide open.

    MASSIVE oil leak mechanic can’t find

    Ok one thing easy to miss is a rubber plug that’s used in a marine application when the dipstick goes to the bottom of the pan and not into the block. A little rubber plug just above the oil pan in front of the starter.

    Outdrive gasket pushing out

    Thanks for posting that article up I’m going to print it out! On my Cobra I just coat the gasket and the sealing surfaces on the drive & transom mount with Evinrude gasket sealer and also coat the 6 studs with the same. No leaks nor difficulty getting the nuts & drive off even after 6 months in...

    Tired of carpet! Looking for something else?

    I had mine redone with non skid gel coat about 15 years ago and it still looks pretty good now. If your boat has wood cored decks as most boats older than 15 years do you don’t want anything to trap moisture .

    1990 omc cobra 4.3 won’t rev above 2500

    Good point Is the throttle valve in the carb opening following the throttle lever opening? I had a similar but not identical problem years ago and it was the anti siphon valve on the gas tank. Mine would rev in neutral but would not plane out the boat.

    1990 omc cobra 4.3 won’t rev above 2500

    So pump is ok but you still have a lot to check. If you have a boat with the points distributor you really should have a dwell meter. I set mine at the lower end of the dwell range because dwell & gap are inversely related. So lower dwell equates with larger gap and the points will stay in...

    need help figuring out how to remove a starter from a 1996 4.3GL

    You might need to remove the exhaust on that side to get at it. Make sure there is no water in the cyls that kills starters and ruins engines.

    Volvo Penta 5.0 GL-H loss of rpm

    Holley 2bbl. Was the power valve replaced & is it the correct rating for vacuum readings on your engine? Power valve on these functions as an enrichment device. What do the center insulator porcelain look like on your spark plugs? Blistered white (too lean) or black/brown (too rich) should be...

    Volvo Penta - E10 Petrol/Gas/Fuel safe?

    I've been running it herer for approx 15 years (we have no choice, its forced on us by our "helpful" goverment officials) and the one thing you may find is that if there is varnish build up in your tank it may clean it out and clog filters. So, keep a few extra water separating fuel filters on...
