    Mercruiser 5.0 replacement

    Your cylinders look OK, I'd carefully clean off the old head gaskets, clean up the block deck and measure it. If both sides are good, take the heads to a machine shop and get them checked out, might just need a valve job but might be cracked. Reman small block Chevy heads are reasonably cheap.

    Mercruiser 5.0 replacement

    if you look close you can see I have a stuck valve like yours, prob due to water in the cyls from blown head gasket.

    Mercruiser 5.0 replacement

    I had the same problem on my old 4.3, but it ran fine for 2.5 seasons before getting a bit of water in the front 2 cyls. I checked the block deck with a straight edge and feeler gauges as per GM specs (no more than .003" variation) after really cleaning up the block deck surfaces. I took the...

    1992 OMC 3.0 Cracked Block

    I'd pass that rumbling noise sounds like bad bearings. Don't waste your time

    Volvo Penta 5.7 TBI still being a pain

    You replaced the anti siphon valve but did you check the tank pick up tube for a screen clogged with gunk? Some have a screen some don't.

    Twin Big block OMC Liberator

    Nice boat! That was their top of the line…I’ve had a Cobra powered boat for 24 years. I don’t think the drives used with the Ford 460 was the cone clutch; it was what was called the Baby King which had a normal Cobra upper gear housing and the bigger lower unit from the V8 Evinrude outboard. As...

    West Marine going out of business... and I can't think of anything I need!

    On all of Long Island we will have 2 stores left after this "restructuring" on in East Isip and the other in Patchogue. My local store is closing for sure. I did pick up some deals on motor oil and a few other things. Luckily we have a great local marine supply store who supplies a large marina...

    On these oldies with a points distributor with centrifugal advance no jumpers needed! It's all mechanical.

    Tools that younger people would not recognize.

    Try explaining the relationship between point gap and dwell to a youngster or the concept of total timing advance lol. Old School Tune up just like we did in the '70s once a year. the # on the tach dwell is 660 rpm not 66* of dwell lol. these 4.3s get 39* + or - 2* dwell angle (point gap .018")...

    No Reverse or Neutral....just Forward VP

    With that plastic cover off, Have someone watch the shifter bell crank on the outdrive while you work the control t see if it is moving as it should. It it’s not moving as it should you have a cable or control problem

    stripped SX-A (3L VP) dipstick threads

    If you have a decent automotive machine shop they could fix that easily.

    1996 Penta 5.0Fi and SX COBRA

    Well it’s hard to say from looking at the clear line but the engine seems to be hunting/surging. If it doesn’t run any better when run on a seperate fuel tank that suggests that the issue isn’t your fuel tank pick up tube or anti siphon valve. I have never had a boat with EFI so I don’t know if...

    1996 Penta 5.0Fi and SX COBRA

    With fuel pumps, pressure, volume and vacuum are all important. pressure and volume are obvious, but vacuum will tell you if your anti siphon valve is stuck/clogged or if there is a screen on the end of the fuel tank pick up tube that is blocked by crud. Using a clear fuel line between the fuel...
