Anybody Recognize This Coating on UW Metals?

When I bought My Cabo there was a fresh coating was on all the underwater metals. It has performed well and after 4 years I would like to apply a fresh coat. I just don't know what it is. I can see brush strokes on shafts that to me implies it is not very thick like what I would expect from prop speed. Any help would be appreciated.

The shafts haven't really changed but the props and rudders have 75% worn off. Truth is I don't need to have anything on the u/w metals as the water is brackish 50 to 55 degrees and boat is under a roof so it gets almost complete shade. This was on when purchased and I would like to either touch it up or if it wipes off easily I may do that as well. I haul every 9 months to do zincs and look over bottom. Typically 20 min with a wet scotch-brite general purpose pad I can have any grime removed. Once I can confirm what this is then I will contact manf regarding touchup or removal.

Thanks guys.

The only time it bothers me is when I have touched up my bottom paint and applied new zincs then go to take a pic. It looks half azz so to speak as the rudders and props are clean but look like they are half worn. Now that I know what it is I will atleast know my options when I haul the boat in a couple weeks.

Thanks guys.

I have no problem replacing cutlass bearings if needed. I have looked at that each of the last 3 haul outs but am not sure what my sign for replacement would be? If they look worn to you pro's then I will jump on it. Power is smooth and when I did shaft seals I checked for play and there was none.

Thanks for the input guys. Hauled out on Monday and went back into the water today. Replaced the cutlass bearings and condition was not horrible but upon removal you could see that the Port side (shown in pic above) was starting to lose one chunk of rubber and it was a good time to just replace them both. With the hydraulic tool it was an easy job. Had never seen that done before. Pulled the props and had them scanned. Stbd was perfect but he found on blade on Port with minor issue. Fixed that and bead blasted prior to prop speed application. Removed a transducer and sent to Airmar for warranty replacement. Did one coat of bottom paint and zincs along with full hand wax of the hull. Received the new transducer via overnight and got that installed. Had some thru hulls that the paint was starting to flake so for now I removed the remaining paint and cleaned them up while Transducer sealant was curing. Back in house and all good. Thanks guys.

I replaced shaft seals a year and a half ago. Pulling the shafts is not easy as the coupler connection takes some time to disconnect.

No yard to point things out. Just me. I brought in a independent guy with the hyd tool to do the cutlass bearings I had bought for $200. Had a friend who is another ind contractor to help wax hull.

The Prop Smith tool was another great tip from the forum and that has been a great purchase and very fortunate my props were already set up for it.

This was when slid back doing shaft seals a year and a half ago. Was just showing that there was no bearing as discussed above.
