[C38] RPM for smooth transmission change

Pierre,

My experience is that engine RPM needs to be as low as possible.  Throttle back until you feel the spring but not further or else the engine will shut off.  This takes some practice :)  Any higher and you will hear the clank of the damper plate protesting the gear change. With this said I experienced a bad shift yesterday after years of practice :(

Good Luck!

Hello All

I just read every posting since 2005 containing the word "transmission" and I did not find what I was looking for.

It seems to me that I need lesser and lesser RPM to effect a transmission change, very close to the point of stalling. I don't have an idle setup, the boat's stock throttle goes all the way down to cutoff so it's a matter of listening to the engine which sometimes is difficult in high winds.

What could be causing the transmission's lack of proper shifting until the RPM is very low? Is time to rebuild/replace/sell the boat?

Thanks for your time.
