Do any of you guys change out the zincs on your engines yourselves? Obviously, the inboard zincs are easy. Any tricks or tips to getting to the outboard zincs? Special tool? Need to hit the gym? I just can't get those to budge. Getting old isn't for the faint of heart!

Yes and I learned the trick from @ttmott using loctite anti-seize on them. Done mine several times and while it does require boat yoga and a good ratchet it can be done by us mortals.

Doing mine today. Same as @ocgrant
A good box wrench, ratchet and antisieze for the threads.

About 80 hrs on these last season.
I have to believe that fresh water flushing helps!
 
Thanks for the responses, guys. Now to find someone (or pay) to have them removed and then apply the anti-seize.

I use permatex, was recommended by my Cummins guy
Permatex 80632 Thread Sealant with PTFE, 4 oz. , White https://a.co/d/1giEZTU

Interesting - for the anodes to work they must have electrical conductivity to the things they are threaded into. Isn't a typical thread sealant, especially with PTFE going to tend to electrically isolate?
 
I thought similar and he swore up and down this is what he uses...

Does anybody have rusty SS washers on the inside end of the strut bolts? Is this a common issue on our models? Have you updated to brass bolts washers and nuts? By the way, accessing them is very complicated...
 
I think I may have asked this before but what are you guys seeing for trans temperatures when running for awhile? Any difference port or starboard?
 
I started collecting all sorts of that data last year....

You know I have pods so YMMV, but my temps run from high 130s to mid 140s. Stbd usually 5=8 degrees warmer than port..

Ok so interesting...

I am seeing @2300 rpm 147 port & 140 starboard running for 30 minutes in 80 degree sea water. Both my engine coolants are at 174. So I was thinking I might pull my trans cooler out and inspect / flush on the bench. Being it is the lowest cooler in the salt water loop I am thinking more prone to build up and debris. It just bugs me the almost 10 degree difference.
