Suzuki Oil Injection

[Kiwi]

JB, I'm interested in your opinion on something. I just read your response to Lunker 10/31/01 re his question of what outboard to purchase. In your reply you mentioned "On a 2 stroke engine, I'll still take carbs, (and premix) but on a 4 stroke EFI is not only much more reliable, it is more efficient and easier to use"<br /><br />I have a 1989 Suzuki DT85, it's oil injected. By your comments if you owned this engine would you disconnect the oil injection and premix the oil & gas yourself or would you rely on the Suzuki warning system to let you know theres a problem BEFORE its too late ? It has an oil flow & oil level warning lamp/buzzer.<br /><br />Thanks<br />Mike

Re: Suzuki Oil Injection

G'Day, Mike. You are correct. I would probably disconnect everything associated with oil injection and run premix. My reasoning is that there would no longer be ANY chance of the engine running without lubricant.<br /><br />I have no personal experience with Suzi oil injection systems and have heard no complaints.<br /><br />I just believe that if a failure can occur. . . sooner or later it will.<br /><br />Red sky at night. . . <br />JB

The thing has allready made it how long the way it is, and you want to make changes now?<br /><br />Some of those old injection systems were flawless.

Re: Suzuki Oil Injection

Hi Kiwi,<br /><br />I have a much older suzuki DT75 (only has oil level warning). I am not a experienced boat owner but I have thought about this problem too. Oil injection probably reduces carb problems if you don't get to use your boat regularly but if it fails $$$$$$$.<br />i decided to trust it but each maintenance I use premix until I can verify that the oil tank level is dropping. Also if you run out of oil use premix until you are sure. There is a filter for the oil which may need occaissional replacement. Are you sure the monitoring works? I check the low level alarm each year but I not sure how to simulate low oil flow without opening the system (really not advised) How does it sense oil flow?<br />Cheers <br />They seem to be reliable engines.

Re: Suzuki Oil Injection

By not using the injector you have a potential human error everytime you fill the tank, just forget once and thats all it takes. It can happen easier than you think. <br /><br />There is no warning horn for this type of failure. I would like to see data on how many motors have been destroyed by pump failure, or human error during manual mixing, I bet someone who works on them everyday would know, someone who worked on motors in the years before injection systems and after would probably know best.<br /><br />I speak from experience, I have only wrecked one motor in my life, and it was a liitle Merc that required manual mix, But I guess the bright side is, it was only a Mercury

Re: Suzuki Oil Injection

Thanks JB, its interesting as you say, I have heard no real complaints about the Suzi oil system, or infact the outboards as a whole, so that in itself must be good ! <br />Yepblaze, I have only had this boat for a few months, prior to that I had a '73 Evinrude, so this is the first motor I have owned which has oil injection, and as yet we dont have a trust thing going !!<br />Sirlespat - Hi from across the ditch ! Good idea about the premix after a maintenance check, I might do that. According to my workshop manual there is an oil flow switch in the oil line that checks oil flow. I guess it must be very sensitive as oil would be flowing very slowly. Like you I have no idea how to check that sensor, I reckon 'leave well alone' on that one ! I have checked all the other warning system sensors and all are working ok. Where in Oz are you ?<br /><br />Thanks for all your replies.<br /><br />Mike
