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.

    Ray.... On that engine, the warning system is as follows.Constant steady beep = Overheating.Beep every 20 seconds = Oil level at 1/4 tank.Beep ever other second = VRO failure, No Oil, Air in oil line, Oil restriction.

      Re: alarm buzzer

      thanks joe for your info but i have another question i was told by a sales person that my johnson tracker pro series 90hp motor was a 2 stroke and i needed to use 2 stroke oil i think it is a 1991 boat i had never pulled the top off the motor untill today to check the oil line i noticed then it has 4 spark plugs 2 on each side is this a 4 stroke motor i have no clue i have never owned a boat before the person i bought the boat from was using 4 stoke oil because the empty bottle was in the boat when i went to buy more to fill up the tank thats when the salesman told me not to use that type of oil to use 2 cycle outboard engine oil i had a half tank of oil and added the 2 cycle oil to fill the tank took the boat out with no problems as the oil ran down i continued to use the 2 cycle oil untill the tank was full again thats when this past week the buzzer started going off could this be my problem if so can i drain all oil out of tank go back with 4 cycle oil and be ok or should i have it checked out before doing anything thanks for any advice you have ray

        Re: alarm buzzer

        Raymond,IT IS A 2-STROKE engine. Use ONLY, TCW-3 rated 2-stroke oil. I would suggest you get all of that old oil out of that tank. You have to determine the sequence of the beeps your getting to determine the cause, as Joe Reeves points out.Don't spend alot of time doing this, those warnings are trying to tell you that you are close to impending mechanical disaster.If you're uncomfortable doing this, take it to reputable dealer and have them do the following.1. Clean oil tank, replace filter and refill, prime oil injection system.2. Change water pump impeller or install water pump kit.3. Check lower unit seal integrity, (pressure and vacuum test) and refill lower unit.4. Check engine timing.This will cost you several hundred dollars but will save you thousands.

          Re: alarm buzzer

          I have a 1995 150 hp Suzuki outboard, with a overheat buzzer problem. When I start it up, let it run for awhile to warm up, then throttle up. the buzzer goes off. My local dealer said to check the heat of the motor with the cover off, and I did this, and it wasn't overly hot. He then told me to just shut the motor off, and then start it again and go on my merry way. This works, but if I don't let the motor warm totally up -- many minutes and often many many minutes-- the buzzer goes off again. How long does this motor have to warm up to avoid having the buzzer go off? I am using it in warm water (South Padre Island, Texas coast) in warm weather of 80 degrees or so, so warming it up isn't a long problem, altho if I don't let it idle for quite a long time, the buzzer goes off.... and yet the motor's water cooler is running fine, and I replaced the impeller to make sure it is getting the maximum cooling water.... thanks for your help on this.. Jonathan

            Re: alarm buzzer

            The number of cylinders (spark plugs) the engines has, has no relationship of whetherthe engine is a 2 stroke or 4 stroke. Most 2 stroke engines require oil and fuel to bemixed together at a usual 50:1 ratio, or they have a two stroke oil tank that automaticallymixes the oil with the fuel. A 4 stroke engine, is just like your car, it has a cam, intake and exhaust valves, and a oil sump system with filter. The gas and oil arenot mixed in a 4 stroke motor, it is internally lubricated. The two stroke enginesrequires a special blend of two stroke oil for mixture lubrication and regular oil forcars will not do the job and will damage your 2 stroke motor.

                jjskier,Your Suzy isNOT performing normally. If you have plenty of water flow, you may have an oil injection problem.You should be able to hold your hand on the top cylinder, without burning yourself, on a fully warm engine.By the way, you'll get more responses to your question if you post a seperate topic in the "Engine and Motors" section.Good luck!
