95 dt150 help please

[peter13]

From what
i have read, on land it runs fine. under a load, it doesnt exceed around 2k rpms. the more throttle the more it bogs. I have disconnected the temp sensor and the rpms go up. also i have played with disconnecting the oil flow and oil level sensors and it changes alittle. So, i am under the assumption that it is in safe or limp mode. i am waiting for the monitor gauge as we speak. hopefully that will help alittle

Well i guess from your comment that it is in limp mode is why you didnt specifically answer my questions? Why do you think it is in limp mode? What code/s is it throwing?

[peter13]

sorry to say that my remark was that of sarcasm. no one helped what so ever on this forum

[aquamort]

how did you go peter?

[peter13]

thanks to everyone for all the help!

from what I am reading, it is in limp mode. I changed the oil sensor and disconnected the temp sensors. after disconnecting the temp sensor, the motor idled nicer, but still stuck in limp mode! kinda sad running a bass boat 7 mph on the Hudson river

Hi Peter, So when you say bogs down is it missing? or just not producing power? If its not missing and just not producing power Id look at fuel supply and possibly ignition timing to start off with.

I swapped out a Force 150 with a 95 DT150. The motor runs strong on the ears. Dump the boat in the water, idles great, pop it in gear and it bogs under a load, barely getting to around 2000 rpms. full throttle does not exist. there is a sweet spot around 2000 rpms where it actually runs smooth allowing the boat to cruise at a whopping 8 to 10 mph. if I play with the tilt button, it makes the motor stumble and run worse. I gave the boat to a supposed mechanic, not so smart. anyway, does anyone have any ideas? the plugs new, gas line from primer bulb, new/ and the sad part is the stripers are running in the Hudson and my boat isn't. please help
