I have an AQ200D with a 280 drive with three lube points. One is on the drive and two are inside the boat.Of the two that are inside, I had trouble with the one to the starboard side of the bellhousing.I hooked up the grease gun and felt resistance,like the zirk was clogged.I dont think any grease went in. I removed the zirk and hooked up the gun and it was normal-grease came out of the other side.Put the zirk back on and I cant squeeze the lever on the gun.I think this is to grease the steering.Any ideas on whats wrong?Thanks for any input.
