is a Perkins 4.108
and my transmission
is a Hurth
hydraulic model (don't have exact number in front of me)
runs great while in neutral throughout the throttle range. The moment I put it in gear
, either forward or reverse, it bogs the engine down and if I did it from idle throttle, it will usually kill the engine. I can engage from a little higher than idle and it will produce minimal thrust while bogging down to an idle RPM
level and putting out black smoke (I assume unburnt fuel
from me trying to throttle it up)
Some things to note:
1) Shaft turns easily by hand.
2) Rubber coupler between transmission
3) Loosening shaft packing doesn't help.
4) In neutral, at idle, the shaft turns slowly on its own...always has.
I've run this by my "Perkins guy" and he has no idea. I have about 6 people coming to stay with me and go sailing for the 4th....HELP!!!
