  1. Re: Omc cobra and Volvo penta sx interchangable parts

    Lets not leave out this part:
    Yes they did not manufacture the dog clutch units after '93. If you look at both drives and transom mounts what you will easily see is that:

  2. Re: Omc cobra and Volvo penta sx interchangable parts

    The only way is to compare parts numbers...so you would have to look at a Volvo and OMC on line catalogs. Also keep in mind the OMC Cobras for model years 1994-1998 are the same as the SX... just be...

    Re: Dwell angle vs Point Gap

    Back in the old days we used go-no go feeler gauges to do mechanical valve lifters and points, I had a 65 VW Beetle and never used a dwell meter!

    Re: Overcooling off plane

    My OMC has that same exact t-stat housing (VP took it from OMC actually) and what I have found is that it is common every now and then for a small piece of rust from the cast iron intake to lodge in...

    Re: Dead Volvo Penta 5.0L

    Oh and Rick I was only kidding about the engine being the same as that in a 70 Chevy. Yes I realize we are talking about a Vortec V8. But still they are quite similar. Vortec heads and roller lifter...

    Re: Dead Volvo Penta 5.0L

    The engines are not branded as Volvo or Mercruiser, they are GM small blocks like you had in your 1970 Chevrolet! The long blocks (block+cyl heads) are the same, its the accessories that are all...
  14. Re: Replace 2000 Volvo Penta 4.3L with 1988 OMC 4.3L

    Well the exhaust manifolds from the Volvo will fit for sure because that's what I used on my '88 OMC to replace the old batwings. The '88 has a mechanical fuel pump, and different intake, it can be...

    Re: Dwell angle vs Point Gap

    Agreed that .031 gap will limit the time that the coil saturates and will limit spark. BTW, in my OMC manual the points gap for all the engines is pretty similar, .018 for the 2.3 4 cyl, .019 for the...
