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.

  • 1982 70 HP Evinrude Metal in Gear Oil


    I'm looking to purchase a 1982 70 HP Evinrude.

    The owner passed away and the nephew is selling it. The grandpa claims there are 20 hours. Unlikely, but definitely low.

    I checked the compression, 150 all three cylinders. Starts, runs, shifts excellent. Pees well.

    Two issues:

    1. Oil drips from around the prop.
    2. The gear oil was clean, like new, very hard to open the screw, so I assume it hasn't been touched in a long time. However, there were some fine metal shards stuck to the screw (magnetized). No water.
    3. I can tell it was used in salt water, there is some evidence of corrosion and sand from the ocean. No idea if it was flushed or not, how could I tell? What issues could arise?

    Are theses issues significant? Will they be an expensive repair? Or is this normal?

    Were you running it on a hose, if so the oil around the prop could be unburnt fuel mixture, a common event. Metal in the lower unit is never a good sign, I have seen some very small particles at times that never caused a problem. It's had to tell if there is any damage inside by your description. By looking at it you would not be able to tell if it was flushed. If the price is right, it might be worth the gamble to me.

      I was running on a hose, yes. The price is good, it's hard to find these old motors for $1000 in good shape.

      Can you tell me what the repair is if the shards are an issue? What would need to be rebuilt?

        Also, I think this motor has been sitting for awhile. Is there any preventative maintenance that I should do? Probably need a carb cleaning?

          You are going to have to pull and disassemble the lower unit to inspect it to find out where the metal is coming from. Until you find out what is making metal, you woun't know about cost. Maybe you could use the metal in the lower unit to get the price down to help with repairs if needed.
