1999 DF 70.
- Initially fuel problems, - would not start - Cleaned, replaced or tested entire fuel system to injectors. Fuel pressure test ok.
- Checked oil pressure and compression - 1 cylinder 185, the rest 210-220
- No changes in original prop
- Changed water pump - great flow.
- Swapped ECU with other engine - no difference
- New starter, solenoid.
Symptoms: Engine is port side of 2 on Glacier Bay. Both start and run smoothly. After a few minutes warm up, going up to WOT, this engine gets to and stays at 5200 and then slowly drops to about 4000 max. The other runs smoothly to 5500+
20 minutes running checking temps (145 max), slow down to enter slip.
Engine stalls. and then seizes - will not crank.
Fifteen minutes in slip, engine will again rotate manually.
Ideas on what to check next?
Thanks!
