Doesn't miss a beat


Now 7 years old, my DT40 hasn't missed a beat. Serviced every two years just fill it up and go. Quicksilver oil has worked fine. My DT40 starts first time on cold starts at the ramp, just give it revs and choke. Not the most fuel efficient or quiet motor but it is a two-stoke and a good option if you are after something cost-effective and reliable. Saying that tho, I would always recommend a 4-stroke over a two stroke especially at 40HP and above due to efficiency and convenience with refuelling.

I’ve had great difficulty downloading a manual for a dt40 04005 - 410028. Suzuki website stops loading and boats.net doesn’t seem to have that model listed.

Why does my suzuki 15 hp 2stroke outbourd moter run roughly with new fuel

Assuming you are using the correct ratio, and you've cleaned your carb out thoroughly, then it's possible you are getting contaminated fuel. Some fuel has bioethanol in it, which can absorb water from the air or the tanks in which it is kept. A gallon of fuel can absorb up to four teaspoons of water in suspension.

It's a major problem for boaters. Your local chandlers should have fuel treatments that can handle small amounts of water, they also stabilise your fuel. Any more than that and you need a water separator, but I would concentrate on making sure your fuel is clean. Mae sure the additive is ethanol (E10) compatible.

If the problem is not water, test your compression on each cylinder
