I know of no failures in the Suzuki oil injection system. I would keep it.

If you do disconnect it, use a 50:1 ratio.

Make shure it doesnt have an overheating problem.
to get to the poppet valve you will have to lift the powerhead off. stupid right??
pain in the ...
other than that the exhaust plates do rot out specialy on saltwater engines.

good luck

Re: buying dt140

I have that very same motor, 1997, just bought it and it's blown twin about a month ago. It is replacing a DT115 that has a scored cylinder. One suggestion, take off the oil tank and dump it out. Check for anything suspicious in the bottom. Sludge in the bottom of the tank on my 115 caused the oil flow alarm to go off but it always happened out on the water where I couldn't see the alarm light and thought I just had an over rev problem because of the prop I was using. Man am I an idiot.

You will have to bleed the oil pump when you put it back together but the shop manual covers that. You are going to buy a shop manual right? Browns Point Marina has about every new part you would ever need. I do too, give me a shout if you need anything as I am selling off the DT115 and DT140 parts.

That price is great as well. I think the blue book is about $1900 without controls or a prop.

If you can check the compression, better yet a leak down test. Also look at the oil in the lower unit making sure there is no water in there.

You only have to bleed the oil pump if the oil tank is removed or you run out of oil. It holds over a gallon of oil so you should never run out if you top it off after every trip or two. Bleeding is easy but very messy.

No worries, you shoud be pleased with the engine.
