I noticed this while out on the water yesterday, one of the trim cylinders looks like it's pulling away from drive. Anyone ever have one of these pins shear? That's the only thing I can figure that would cause this. Was just wondering how difficult these are to swap. Not sure if I should do it on the hoist or put boat on trailer. Boat has always been used in fresh water. Thanks for any info.

Sorry fat fingered and posted prematurely! To continue... Retainer clips are still there thats what's holding rod end on. Seems like the whole pin is moving out on that port side. Need to disconnect the cylinders from the pin, just wasn't sure what to expect. Are the cylinders under constant load and cause shaft to extend out? And how difficult is that pin to get in and out? Just wondering if this is something I should do on the trailer.

have you pulled the entire pin/shaft? maybe that shaft is broken? That shaft will pull all the way out, if you lift the drive slightly as you remove it the tension is relieved and the shaft pulls out easier

Removing this pin is simple. Trailer your boat and trim down until the skeg just clears the ground. The only load on the pin is the out drive's weight. <50# when down low. Remove an end cap and the E clip. Take the weight off by lifting the anti-cave plate and pull the pin out while jiggling the drive. Mine is always a little stubborn, So I tap it out using a wood dowel or 3/8" socket extension. It looks like you may be missing an outside bushing, allowing the pin to slide excessively. With all parts in place, bushings, washers, and E clips there is just enough room to get the E clips set, and not much more.

Yep, that's exactly what that orange is, the bushing stayed in place when that trim cylinder end shifted. Gonna hopefully tear into it tonight and I'll post what I find.
