the blue things are broke. Could that be why the starboard side wouldn't do anything? It was cavitating really bad. Lots of fishing line wrapped up in these also..
Seems like everyone I call says they are obsolete.
I've read here you can go without.
And to cut it and use just the area through hull, but one is broke.
Could I just leave the whole thing out?
They were just to keep ski ropes out of the driveshaft but most broke and were not replaced. THe skis that use the same drive components never used them. So no, you don't need them and it will not cause any issues with them removed. Just don't run over your ski ropes
