Recently I’ve only been able to get 2000rpm max in forward
gear. Neutral and Reverse
work fine with full
power. There is also a little bit of white smoke if I try to throttle past the 2000rpm max.
So after a new mixing
elbow and a few other test, I tried to spin the prop shaft in neutral and it spins freely to the starboard side but not to the port side. The odd thing is when in
gear, Forward is to Starboard and Reverse is to Port. The
engine is
3gm30 with the vdrive KM3V
transmission.
UPDATE: Upon further investigation, the spinning in both directions finds resistance. Some times it spins free and then it gets tighter and tighter and then it kind of breaks free and spins freely. Almost like screwing the top onto a jar and it slips past the tightest threads and has to be tightened again.
Are there any other test I can do to figure out more or just have a
mechanic pull the
transmission off. At one point I thought it could be from a worn cutless bearing does this behavior make sense? There is definitely some play at the prop end.
Thanks
