Alarm buzzer

rpark1359 i have a Johnson protracker 90hp motor i think a 1991 engine starts and runs fine but last time out after about 4 or 5 min of running a buzzer sound started coming on from where the throtle control is can anyone tell me why this is happening (it is full of oil) 2002-04-21
Joe Reeves 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.

rpark1359 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 2002-04-23
djohns19 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.

jjskier 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, an 2002-04-24
videofxr The number of cylinders (spark plugs) the engines has, has no relationship of whether
the engine is a 2 stroke or 4 stroke. Most 2 stroke engines require oil and fuel to be
mixed together at a usual 50:1 ratio, or they have a two stroke oil tank that automatically
mixes 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 are
not mixed in a 4 stroke motor, it is internally lubricated. The two stroke engines
requires a special blend of two stroke oil for mixture lubrication and regular oil for
cars will not do the job and will damage your 2 stroke motor.

djohns19 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!
