Difficult shifting

Anyone have an S2, Yanmar engine, that is really, really hard to shift into forward and reverse? We disconnected the cable at the transmission, and the shift lever is smooth as silk, like cutting butter. Hook it back up and you really have to lean into it to get it in gear. There is fresh fluid in it. Maybe wearing out inside?

Re: Difficult shifting

Do you mean the shift lever on the pedestal or on the trans? If at the trans seems like it's a cable problem.

Re: Difficult shifting

disconnect cable from trans & throttle at engine end. try shifting the control lever at pedestal and at engine side and see where your problem is.

Re: Difficult shifting

Shift lever at steering station and cable are not the problem. We disconnected the cable at the transmission, and cable and shift lever at the steering station were fine. The problem is at or in the transmission. Also, no problem with throttle whatsoever.

Re: Difficult shifting

Disconnect the cable, start the motor, and see if you can change gear by shifting the lever by hand. It sounds like you will not be able to. If so, then you have a gearbox problem.
Watch that the shift quadrant on the gearbox is not fouling the water pump or something. It happened to be last winter when I drained the coolant on my Volvo MD17C. I inadvertently moved the water pump a wee bit, and the gearshift qaudrant was catching the pump. It took a while to see what had happened.

If you have a gearbox problem, then at least you don't have a Volvo gearbox on there. It would be financially terminal if you did.
