Suzuki Waring Alarm

[sethgs]

I have a 1987 DT85 Suzuki with oil injection. Currently, the motor seems to be running at top performance, since I replaced the head gasket. Though, a warning alarm is bugging me now. I can run the boat all day with no problems at nearly full throttle. But the second I push it the rest of the way, an alarm will begin buzzing after about a minute of running full speed. I feel its an overheat alarm because it happened once before when I got some mud in the water intake. Right now, I don't think its overheating because the water isn't too hot, and it doesn't occur at any other speeds. An impeller change is scheduled for the next week or two, but I would appreciate any help as to what this annoying alarm may be. Thanks.

Re: Suzuki Waring Alarm

could be low water flow, I dont think that model had a temp alarm, or it could be the filter in the oil line between the tank and the pump. sometime about your year model they added an alarm for low oil flow.

Re: Suzuki Waring Alarm

Hi,<br />There is probably a water flow sensor on Your Suzuki and it can be "dead". That happened on a Suzuki DT65 (1991) I had before. It gave (false) alarm on (low) waterflow = overheat alarm. It was actually a defect water flow sensor and when it was replaced with a new the alarm stopped.<br /><br />/Bo

Re: Suzuki Waring Alarm

Thanks for the help so far. As far as the alarm, will the oil level alarm sound different than the water flow/temp alarm? The one I'm hearing is pretty loud, and it doesn't chirp, as I've heard that some alarms make a chirping sound. Thanks in advance for the information.

Re: Suzuki Waring Alarm

nope, both are a steady tone on that model, without the monitor its impossible to tell which is which. myself I would run premix until the issue was resolved one way or another.

Re: Suzuki Waring Alarm

Do you think that it is more likely to be a partially clogged oil flow filter. The more I think about it, that seems more reasonable because it only occurs at WOT after about 10-20 seconds of being there. That's not enough time for the water temp to climb and thus kick on the alarm. At least, that's kind of what I think.

Re: Suzuki Waring Alarm

run it on premix with the oil alarm disconnected. dont FORGET TO premix.<br />or just dissasemble and clean the oil filter.<br />if your oil filter does not have the two wires going to it it does NOT have a flow alarm. I cant remember the exact year they incorperated the flow alarm, <br /> all of them had a level alarm.

Re: Suzuki Waring Alarm

The oil filter itself does not have any wires going to it. The indicator light shows a full tank of oil, which is correct, so it doesn't seem likely that alarm would be for oil level. If the alarm is an indication of overheat, I am aware of the temp. sensor on the head, at the rear of the motor. Is there also a water flow alarm on this motor? If so, where can I look for it at? By chance, there wouldn't be an alarm for oil flow coming from the pump or somewhere else, would there? So many possibilities!! Thanks.

Re: Suzuki Waring Alarm

I had an '85 ... my symptoms were at a lower RPM, but never the less the same. If there are wires attached (meaning there's an alarm) take out the flow filter and clean it (extremely fine mesh). The nuts are sealed so it might be better to just replace it (not ridiculously expensive). Mine developed after using some old oil; removed that from the tank and haven't had a similar problem in years.

Re: Suzuki Waring Alarm

if your filter has no wires its a model with no low flow alarm, <br /> it does have a temp switch. sounds like you have a blown headgasket or a defective pump. <br /> that is applicable for 86,87 in 88 they changed from a temp switch to a float switch to detect water flow.temp switch was reintroduced in 92.

Re: Suzuki Waring Alarm

Lord, I'd hope its not a blown head gasket. I just replaced the gasket. Before I installed it, I coated it with copper seal. Some of the bolt holes have heli-coils in them. The head gasket should not be a problem, as the motor seems to run with more power and compression now. The alarm did occur the last time I took it out before the head gasket change. I'm going to replace the impeller anyway this week or next, which certainly won't hurt anything. I've heard of some people actually drilling small holes in their thermostats to allow more water flow. Do you think this is a good idea? Thanks for all the help you guys have provided!!

Re: Suzuki Waring Alarm

Mine does that as well but only in cold water. When the water warms up the pressure goes up and it stops. The pump was rebuilt and it works well but the pressure seems about 1psi lower when the water is cold and causes it to beep at an idle. I have delt with it for the past year because it is not too often I run it when its that cold anyway.
