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

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

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

3. Do not take over someone elseís thread (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 thread of your own.

4. If you have a question for the original poster (OP) and the thread 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 thread.

5. By starting your own thread, 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 thread. And those answers will be specific to your particular issue.

6. Please do not post to threads that have been inactive for more than 3 months unless you are the original poster. We have very active forums and any thread 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 thread.

7. Posting at the end of any thread is considered to be hijacking the original posters thread which in turn subjects the thread 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 thread asking you not to reply to old threads. The Red banner will read: Please note this thread has been inactive for 90 days. For the best results, please start a new thread.

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

  • 1988 bayliner capri 120hp 2.3 liter ford cobra omc inboard engine rebuild help ????

    so i got a really good deall on this 1988 bayliner capri and couldnt pass it up so i bought it,this isnt my hobby boat and i picked it up to turn a little profit on it, it has a 120hp 2.3 liter ford cobra omc inboard engine in it, when i brought it home i tryed starting it and it was just making this click sound but everything else in the boat works i mean everything and the outdrive tilt and trim works dead on also. so i did a little research and i thought it might be froze up or siezed ??? the last owner said he hadnt ran it for the last two years and i doubt he even winterized it, so far i tried spraying p-b blaster in 3 of the 4 cylinders i couldnt get the last spark plug out, after i sprayed it i rocked it back and forth and let it sit for about 30 minates came back and tryed turning the bolt on the front of the engine to try and get the crank to move and still wouldnt budge ??? the bolt is just turning itself now. so i tryed putting heavy oil in the cylinders and let it sit over night that didnt work either ????? i though it might of been the starter so i took that off the engine tested it and its working, so now my question is am i going to be taking out this engine and try rebuiilding it ???? or maybe going in and replacing or greasing up a few parts ???? what ever i have to do ??? however i only have a limited emount of basic experience in marine mechanics and limited funding for this so taking it to a marine shop is out of the question installing another motor in it isnt tottally out of the question but i want to stick to the same type of engine and around the same horsepower and year to avoid troubleshooting all the adjustments and modifications ill have to make. and i cant find any people selling this motor around in my area. soo that leaves me with one thing this motor is coming out one way or another but what id like to know is how do i go about taking apart this engine???? to i guess you would say rebuild maybe
    ???? what should i be looking for ???? is their a certain way i should go about doing this ??? i dont know anything really of how to do this???i do have the tools and know how to get it uninstalled and out of the boat and onto the floor of my garage from there i desperatly need some help and guidance on this one any help will be so greatfull thanks.

        You made a big mistake. No one buys dead bayliners to fix up and make a profit on. Let alone Ford powered ones.

        That engine was only used by OMC for 3 years, then it went away. Oh, BTW so did OMC in 98. They no longer exist, just like most of the marine parts for that engine.

          Wow, such a deal. I think that the guy who sold it is quite relieved.

          you should be turning the crankshaft only on one direction, otherwise the bolt will just come off. Did you take the spark plugs out yet? That might be the issue, if the engine has a hydro lock or something other than just stuck pistons.

              Don you are wrong im going to make money on this boat either way the cobra outdrive alone is worth $1000 or more and the trailer is worth atleast $400 and by the way only smart people buy boats for cheap to sell for almost triple of what they paid for it, and these are selling in my area right now for $2000 or more some dont even run and the interior in this boat is like brand new.

              tpenfield : i was able to get three spark plugs out.

              bruce : i couldnt get the last spark plug out becouse the waterpump was in the way but if that might be a reason its not starting i will go do that right now and let you know what happens thank you

              thanks, austin

                  I sold a 1987 20.5' Bayliner with a 5.0L engine back in 2002 to my neighbor for $2500 that ran perfectly and was in very good condition. Hard to imagine you could get $2000 for that one but anything is possible I guess.

                      haha well maybe you should go make your own thread about how don is right then, i would advice go price how much good outdrives are going for on ebay after that you should check out ebay and see how much these bayliners are selling for or maybe even your local craigslist after you do that if your right then youll be telling me that these bayliners with brand new interior a working outdrive and with a complete engine and a nice galvinized trailer with titles are selling for just half the price of what the trailer is worth alone all day in your local classifieds if once you find out if this is true then come tell me if don is right i didnt make this thread for people to tell me how i made a mistake on buying this boat for dirt cheap was a bad idea becouse i know it wasnt i simply made this thread for people to help me diagnose the engine. thanks for your concern though.

                          You haven't proven the outdrive is any good since you can't get the engine to turn over. With the outdrive off you can then determine which one is locked up. For all you know they are both locked up which leaves you with a hull and trailer.

                            Your view on all this is understandable and there are many variations on that theme throughout the threads on this site. Craiglist only shows how much the seller wants, no history on how much it sold for if it even sold, and then if the new buyer ever got it going. Do you have any offers on it yet? If so my advice is: better take one. No way you will come out on this if you have to rebuild the engine to flip it unless someone gave you $1200 to take it off their hands. And with that, I am not even considering having to gut it and put stringers and flooring and new interior in, and any or all of that is more than likely needing to be done to that boat based on your description of the prior treatment of it (not to menton that particular brand's lack of longevity for that vintage). All this plus your description of the application of your own skills ("...greasing up a few parts...") pretty much guarantee this will be a learning experience only with negative profit. I hope not, but odds are it will not go as you are planning now, just sayin'.

                              I still think that the guy that sold this boat is quite relieved . . . However, fixing this boat will be a positive experience because of the knowledge gained in the process.
