Below are some additional forum policies in hopes of all iboats members will follow, Thank you.

1. Please do not reply to old topics or hijack existing topics. Old topics of a technical nature are like a library book, Please do not write in them.

2. Old topics should be considered archives and used for reference only. Please do not reply to them.

3. Do not take over someone elseís topic (aka hijack) with your own question, even if it is similar. If you have a question that has not been covered to your satisfaction in the archives, it is always best to start a new topic of your own.

4. If you have a question for the original poster (OP) and the topic is over 30 days old, send the OP a PM, he may not even visit the forums any longer, or may not notice your question in the old topic.

5. By starting your own topic, you will receive the maximum number of views by forum helpers that may not even notice your question when itís posted at the end of someone elseís topic. And those answers will be specific to your particular issue.

6. Please do not post to topics that have been inactive for more than 3 months unless you are the original poster. We have very active forums and any topic that remains inactive for that long should be considered "dead". It is especially confusing when there is an entirely new question posted to an old topic.

7. Posting at the end of any topic is considered to be hijacking the original posters topic which in turn subjects the topic to be closed if it continues to happen thus not making it fair to the original poster in the future had for some reason he/she needed to return for additional information or provide an update of the problem solved which is always welcomed within a reasonable amount of time frame.

8. Please note that you should see a red banner pop up near the bottom of each inactive topic asking you not to reply to old topics. The Red banner will read: Please note this topic has been inactive for 90 days. For the best results, please start a new topic.

Thank you all in advance for doing your part in helping iboats run a smooth ship.

  • Volvo Penta / OMC 3.0L engine identification - GM or Ford?

    Hi All,

    I recently purchased a 1998 Four Winns Horizon QX with a Volvo Penta/OMC 3.0L mated to an SX Cobra stern drive. It has cleaned up nicely and is running great. I'm currently in fact finding mode (coming from a Yammy 115 outboard) to gather as much data on this boat as I can for my files -a HUGE THANKS to all those that have posted great questions and received great answers from the info I've searched through!

    Unfortunately, I've not been able to find anything here or on the www that provides any way to identify whether it has the GM or Ford 3.0L engine. The shop manual outlines that both engines (could?) have been present that year? Although the manual mentions both, the "identifier blurb" does not provide for any distinction between the two in their "decoding the engine model number" section.

    Do any of you have any idea based on the info:
    Engine: model# 302CPBYM serial# T01311942
    Transon: model# 3868843 serial#T00383398
    Unit: model# 3868814 serial#T00819714

    or know of an area I can go to determine what engine/parts I should be hunting for if ever there are problems? Thanks greatly for any input.

    Howdy,


    ALL 3.0L engines are manufactured by GM. It was never put in a car or truck.

    They were used in forklifts, generators, skid-steers, (and boats!!)

      the ford 4 banger that OMC used, volvo never did, was a 2.3L.
      GM made a 2.5L that volvo never used and volvo just dropped the 3.0 from the lineup this year.
      but there are many about and parts will be avalible for a long time.
      GM dropped production of the 8.1 and 4.3 L motors this year.
      sounds like your not using a FACTORY volvo manual so be aware of the confusion aftermarket manuals can generate.
      no tech questions by PM, they wont get answered.

          Then how come GM Powertrain's website lists a 4.3 for 2011????

            I thought their production engines were all the new modular stuff? Their little 3.0l "iron duke" variant has been a dependable platform..simple, cheap, rugged, if not particularly smooth. The 4.3 was simply a 5.7 with 2 cylinders cut off, so as long as the heads and blocks are available, engine internals will be around 'til ALL of US are long gone.

              Once again: The 3.0L is NOT an iron duke "variant", nor is it related in any way, shape, or form. Two totally different engines!

                  VOLVO PENTA is moving away from the 3.0L. Mercruiser is still using them. Why, I don't know, but my guess is that the money it takes to make the 3.0L engine EPA friendly and still run and last in real life, is just not worth it for VP.

                    Seloc manual - not 1998 factory manual but better than nothing I guess? covers many years and thus variations. From what I've heard and PLEASE correct me if I'm wrong, but there was some kind of "cut-off" where OMC went belly up and Volvo "bought" them out? And changed things up. I had a marina/dealer expressing that I could be in one of the transitional years... If ALL 3.0L are GM, then I guess that's what I have? There's no way it could be a Ford, and yes, that's where I'd guess these Seloc manuals can lead to problems.

                      what we were told by the VP purchasing agent was GM is dropping the 4.3 and the 8.1L engines and VP has enough for about 2 years.
                      VP did make the 3.0 as an MPI version for about 16 months then dropped the 3.0 from the line.
                      mercrusier made it MPI with a catalytic converter for EPA after jan 01 2010.
                      was wondering all last year why the 4.3 and the 8.1 got EPA exemptions.
                      been trying to find more info on that slant 4 1.6L mercrusier with the funny name.
                      havent seen one yet but it should be fun to access.

                            The good news, is you don't have the Cobra drive mentioned in the hastings article, you have the SX outdrive. (Volvo)

                            This should explain the model number for you.




                            The BY indicates a 1998 engine/drive combo. That was also the last year of OMC/Volvo joint venture, as Volvo bought them out completely.
                            You can use Volvo parts and part numbers for all the parts and Volvo manuals since the Volvo and OMC versions are identical.

                              Now that you know what you have, you might do a few things that will keep it running great.

                              If you bought it from a dealer, you might ask them if they replaced the raw water pump (impeller), changed the engine and drive oils, and checked/adjusted the alignment (the regular sched/suggested maintenance) etc.


                              If you bought it from an individual, unless they gave you receipts for the above and you can go to the dealer to verify, you should probably do at least those items when you "winterize" this Fall.


                              Cheers,
