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.

  • evinrude 50hp a few questions

    i just bought a 15` beachcraft trihull open bow boat with a 50hp evinrude model #: e50belcic serial #: jooo1280
    and here are my questions:

    1) what year is the motor?

    2) does it have its own charging system or, do i have to charge the battery evrytime it is needed?

    3) the fastest i could go was 23mph (full trottle) with just me on board (200 lb) is this normal speed for this kind of setup?

    4) when i`m cruising @ 10mph or at any speed and let go of the steering wheel the boat goes to the right immediately is this normal too?
    your help is apreciatted.
    thank you.

    I had a similar set up on a 14 ft Lone Star. That motor should tach at about 5500 rpm. If it is taching that you might try a higher pitch prop to get a little more speed, but it's not going to be fast. It does have a charging system. If it is working you should not need to charge the battery. I believe based on the serial number it is a 1981 motor. As for the steering. It could be the trim tab needs to be adjusted to compensate for the prop torque.

      thank you freddyray,
      but excuse my ignorance in this matters, what is the "trim tab" and how do you adjust it?

        Trim tab is under the anti vent plate just above the prop.
        it is a little fin and it needs to be turned to compinsate for prop torque.There is a bolt that holds it loosen the bolt and turn the trailing edge to the left port side of boat.This tab serves as a sacrifical anode too so it could be eroded or missing.You can get a replacement at your dealer.

            I had a 15' foot Beachcraft with a 50hp Evinrude, 23MPH is about all you will get out of it, See if you can check the foam in the hull, there may be water in it, this can add a couple of hundred lbs.
