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.

  • Just got my First Boat, a few Questions

    I picked up a 1989 Cheetah 1800LS. It has the 3.0L Merc

    first thing is the speedo doesn't work, the pickup on the back of the boat is broke, i think its a pen type. Where can I get one of these?

    I don't think the tach works correctly, at WOT the tach says i'm turning 5,500rpms, its a 19 pitch prop. can it actually rev that high with a prop like that?

    the outdrive was rebuilt in 1998. when you have the trim all the way down, or when you are turning at part throttle it gets very noisy. I don't notice this noise as much at WOT. Is that the gimble bearing? or is it the u joint?

    the left windshield is busted out, the original manufacture of the glass is out of business, the guy who owned it before me said he found a place that will make one but they want almost 600 bucks to do it. Does anyone know of another solution other than plexiglass?

    also should i convert to electronic ignition or just leave it as points. to me points are more reliable, but if electronic ignition will wake the engine up a bit then i will go that route

    yer might be able to get a replacement pitot tube for your speedo here at iboats..
    or, you could forgo the speedo and put some other useful gauge in the hole and use a gps too. fwiw. my boat don't have a speedo so i use a gps.

    some tachs have an adj. on them for switching between 4, 6 and 8 cyl. engines. ya might confirm that it's in the right position if there is one. or. you could test the tach against a shop tach.

    could be either or on the noise when turning. pull the drive and check them out. the gimble brg. should turn w/o feel or noise. it should feel like nothing when you turn it by hand. you can inspect the ujoints at that point too. usually you can lub them. not that it'll help if they are bad. any rust on anything inside the bellows is cause to R&R that item and maybe more.

    there are some windshield parts here on iboats. other than that????? windshields are very expensive. no doubt about it... me, i'm lucky. my windshield pieces are plexiglass and still available from my oem. that's real lucky for me. most oems don't have that option.

    imho, keep the points. just maintain them and they'll be reliable too. i do new ones once a year. so far i've never had a problem with points. some will say that electronic is the way to go and claim better performance. i'm personally not a believer. my engine starts as easy as a fi engine and idles just fine at 600 round abouts...

    that's my 2 cent... mileage may vary....

        Yes, and there are many threads here that explain that process and even how to build an outdrive stand.
