I need help
I have a Yamaha 200hp 2 stroke HPDI with only 155hours on her.
On starting she will gain about 4400RPM and back right off to 3200/3400RPM after a few minutes. There is no alam going off but seems like engine is going into limp home mode. I have had the following done to the engine~:
- Fuel Filters cleaned (not replaced)
- Low pressure pumps checked
- Fuel line checked
- Compression checked
- Removed and cleaned all 6 injectors
- replaced all plugs
- Cleaned VSP
- Checked water sensor (not cleaned)
- Computer hooked up and showing no faults
Am I missing anything. Its getting very close to Calves week and need the boat working. Hopefully someone will have some tips. Thanking ye all in advance.
