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 else’s 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 it’s posted at the end of someone else’s 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.

  • experience with Lehr Motor

    I bought a 5hp long shaft for our sailing club, So far they have put 80 hours on it.
    A couple of small niggling problems the factory fixed , the Kill switch died, Lehr supplied a new one.
    The defective switch had never been tightened properly and had fallen apart ( Qa Problem?) the new one now has 20 hours on it no problem

    A mixture drifting problem was traced to the screw thread on the tapered needle in the carb being too slack. factory suggested a drop of Loctite, and told me if that did not work they would send me a new carb slide assembly.
    The first clue that this is going on , is that the motor will not idle properly.
    Other than that it works fine , starts every time, and as the gasoline motors wear out or get messed up by the gasohol, I will replace them with Propane motors.

    Re: experience with Lehr Motor

    I saw these at the boat show and was looking at their 2.5hp as a kicker for my boat, great idea and for the convenience of the 1lb bottles I would strongly and will consider one

      Following up on my experience with the Lehr 5hp motors. this is now two years later. After I had run one motor for about a year with no problems other than the niggles with the kill switch and the mixture. we bought 3 more. The first motor ( the original.) ran about 700 hours then started having erratic starting problems. this was traced to overheating of the motor. we have a very kelp prone area and it is possible to get a kelp leaf wrapped around the lower strut cutting off the cooling water, the engine just died, the offender saw the kelp leaf wrapped around the strut , took it off, and restarted the motor, however the damage had been done , it was never the same after that. I finally took it back to Lehr for evaluation, they offered me a refurbished motor in trade which we took, they said the motor I took in was beyond repair. I now have another casualty one of the 3 motors we bought has died at 448 hours total time with a thrown connecting rod, I am stripping that motor down now to find the cause, I will post here when I get the results. It should be noted that I am chief of maintenance for a sailing club and have 16 boats to look after, 4 of these boats are now fitted with the 5hp Lehr motors, and the members will play musical boats to get the propane powered motors , because they are much easier to start than the gasoline powered motors.

        A good follow-up report, Brian. Thanks.

        How do the Lehrs compare maintenance-wise against the gasoline motors, barring kelp and ease of starting?
        Please, no PM's (Private Messages) regarding boat/engine problems.
        That is what the forums are for.
        Only forum/moderator issues will be answered in PM's.

          It sounds like your experience has been very good. Most outboards, especially little ones, never see those kinds of hours. Not to mention you have a bunch of "Blow Boaters" running them.

          Thanks for sharing.
