Hi, welcome to iboats ........ you have a 140hp 2-stroke 1996 model ..... well fuel consumption will vary from what you are doing ... eg. ski, wakeboarding, trolling, cruising etc. on my 140hp suzi I use about a 6.6 gallon tank in a hour on ski-ing and wakeboarding ....... the oil level warning is on your tach with waterflow etc. .... do you have no tach with your motor? What boat is it on?

I'm sure is a 40 horse power motor on a 4,20 meters boat , and i don't have any gauges.

I have a Yamaha remote control. I think this is the model : http://www.yamaha-motor.com.au/marine/inclusions/images/remote_r3_c5.jpg

Re: Suzuki DT40 technical details

Typical rule of thumb is 4Gallons per hour at wide open throttle.This will vary depending on load and boat type.
It should be signifigantly less at a reasonable cruising speed.

Thank's for help. I still don't know if my engine can allert me if don't have oil or oil pressure, in my configuration.(engine with yamaha remote controls). Is a second hand engine, not mounted yet on my boat an i heard some rummors about some trouble with oil injection troubles on my motor.

Re: Suzuki DT40 technical details

Engine problems are routinely blamed on the oil injection system by mechanics who don't know how or don't want to take the time to really diagnose what happened. If you are worried about the functionality of the system, Place a mark on the oil tank at the current oil level. Add one pint of TCW3 two-stroke oil and mark that level. Run 3 gallons of fuel and the oil should have dropped to somewhere around half way between the two marks. That indicates the system is working. Until you've proven the system works, you can add oil to the fuel. It will get twice as much oil as it needs but it won't hurt anything.

Hi All,
I hope you don't mind adding to your post, delfinasul.

Here it goes.

I have the 2000 DT140 that I previously complained about the overheating and low output power. Since then I have fixed the overheating problem. I changed out the stuck thermostat and impeller. However, the low output power remains. I have good compression. The readings between cylinders were 125 psi. I have also looked at the possible ignition problem but have found none. I replaced one worn out spark plug boot (#1) and tightened grounding bolts. I have no problem starting and idling around 800 rpm. However, at WOT the maximum rpm registered on the tach is around 4800 rpm. The portable GPS indicates speed at around 31 mph with very little load on the 19 ft CC boat. I have no reason to believe that the tach is off since I believe the boat could run much faster than 31 mph. Previously, have no problem reaching 6000 rpm at wot. I have begun looking at the cyclinder wall sensor which could be bad causing the ECU to put the engine in FAIL SAFE mode thus limiting output power. I do have a burn smell after running the engine on the water. Any thoughts or suggestions on how I can diagnose this low rpm and low output power are greatly appreciated.
