A related question - I have a YSE8 in my Irwin 10/4 - what kind of torque should the clutch be able to handle?
The reason I ask - I've been having some trouble getting propulsion through the weed patches between my marina and the nice sailing grounds.
Not sure if it's straight-up fouling or if the clutch is weak.
I tested the clutch this morning- secured the prop end with a pipe wrench, padded and braced, and grabbed the nut on the crankshaft with visegrips and another pipe wrench, and with the clutch engaged, proceeded to torque it manually until I could slip it. It slipped equally in forward and reverse, best guess at around 80 ft-lbs of torque ( with my finely calibrated arm
This seems that it ought to be enough torque to propel this boat at speed.
I have no idea what the torque output of a 7hp engine ought to be, nor how much torque one of these clutches is specified to be able to transmit.
I did push against the docking lines this morning and it seemed plenty strong - and I have a pruner now to get rid of weeds... but I'd love to know what the clutch should be able to sustain.
