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 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.

    Howdy G. Dane.The OMC loop charged twin and triple, introduced around 1970, are truly great engines.If it is a VRO engine, be sure the pump is working properly. Also, remove, clean and reinstall the ground cable to the block at least once per year. It is usually bolted down to a steel plate, rather than to the alloy block itself and corrosion gan get started under the connection.Good luck. It's a great engine.Red sky at night.. .JB

          Howdy G.Dane. 750USD is a good price for that 50, anywhere.I think your 35 is a cross flow engine. I don't remember when the little three cylinder 25/35 looper was introduced, but if it's a twin it is cross flow, if it's a triple, it is a looper.Red sky at night. . .JB

            Re: 50 HP Evinrude 1983

            I went to see and hear the 50 HP. The compression was 120 on both, warm condition - isnt it a bit low ? My own 35Hp has 125 cold.Looking at bolts and screws under hood, it looked like motor had been in salt water. The owner had it for 6 yrs and it was not in his time, he says. The motor fired right up, ran fine ( earmuffs without load ) and iddled smooth. However it gave a clacking sound, now and then iddling, disappearing immediately when opening throttle. When crancking by hand, finding piston deadpionts, it seemed as the one rodbearing had more play ( double ) than other. Can it run 6 yrs with a damaged rod bearing, or am i too suspecious ?

                Howdy, G Dane. If you are suspicious, pass on it.Red sky at night. . .JB
