Help Tip: If you have a question that has not been answered to your satisfaction in the archives, it is always best to start a new thread of your own. By starting your own thread, you will receive the maximum number of views by forum members.

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.

  • Low pressure in one cylinder

    Late 80 Suzuki 75 hp with low pressure in one cylinder. Runs pretty good just not like it did. Pressure numbers are 125, 120 and 75. Whats the worst case I am looking at. If its like a car motor I was thinking stuck ring, scored cylinder wall or bad valve sitting.

    I currently dont own the engine but need a replacement for mine really bad. Can get it at a decent price just need to know what it should cost on the worst case to repair.

    Re: Low pressure in one cylinder

    Worst case you wiped out the crank and you have to buy a rebuilt power head. If thats the case than your looking between 2100.00 to 2800.00. unless you do the work your self then i think you can do it for under 1200.00. But to me it sounds like your looking at just that piston and you can do all the work your self for about 300 to 500. hope this helps a little.

      Could be carbon or a head gasket, too. Either would be easy and inexpensive to fix. On the other hand, the risk of a powerhead replacement that would cost more than the engine is worth suggests that a "decent" price would be really low, maybe a couple hundred but no more than that.

        Pretty risky.

        Pull the head and see what's happening before you buy.

          Re: Low pressure in one cylinder

          Well price for one bad cylinder is going to be over 2000 dollars. I have worked on cars pulled tranny's and some engine work. How hard will it be to crack the block pull the piston and have it rebored, new pistons and seals myself. Hell I got vacation time to burn. I just dont know about timing and stuff on outboards. Anything else I need to really worry about. Any suggested books.

            If you are an experienced wrench a Service Manual (OEM) would be about all you would need to transfer your skills to an outboard, Swiftshot. Anything beyond that you can find here.

            I still wouldn't offer more than a couple hundred bux for it.

              I got it for 400 everything else works if worst case I part it out on ebay. Guess I will be buying the service manual on how to work on this thing.
