What, I can't sneak any details past you? :silly: Photo shopped the hull stripe. Needed to create a visual for myself, the cockpit cover (and full camper enclosure) came with the purchase over two years ago. PO had it made the year prior.

Bryan, you gonna drill your square shaft and housing for the greasing zerk? I didn't do it but kind of wished I had. Mines all together now and I don't want to disassemble it again.

I haven't decided yet, but I was looking at those options today. If I want to run grease down through the pin I'll have to take it somewhere to have it done. I don't have a press. I don't know why I can't just drill straight through the transom housing and bushing. I see no need to address the smaller bushing and top of the pin with grease, except initially. In fact I haven't even removed the small bushing yet. What do you think?

I've cleaned up the steering arm and wonder how to treat and repaint it. Not sure what metal it is. I may just use a rattle can to prime and paint it. Although I suppose the DPLF should prime it well.

I was looking at mine today and wondering The same thing. It looks like it's possible but I think the hole would need to be drilled on the side of the transom assembly because of the newly installed zerk potentially interfering with the new cover plate.
I think the steering arm is cast iron. I just wire wheeled the rust off of mine and used my rattle can of zinc chromate to prime and followed with black rattle can.

It's really quite simple. BEFORE you reinstall, feel around for the dimple in the casting where the grease zirc used to be on the Bravo One drives. Installed one there and another on top to get the seal covered. Don't get crazy with the grease, but it takes very little to keep the wet stuff out.

Yeah... and the aftermarket stainless swivel pins re cheaper than the OEM carbon steel pins. They now use all stainless parts on their SeaCore drives.

But it looks like they only provided grease to the top of the pin. That's not going to keep water out. No wonder they ditched it.

The grease zirc actually greases both top and bottom if you drill out the shaft. It works like a charm, but you don't need much grease to fill the shaft and seal area.

Ordered parts today. I'm going to just pick up the Trilux 33 at my local West Marine. Their price is the same price I'm finding online. I also ordered the zincs for under $40.

Random thoughts from today-

Was at the boat today between rain showers. Cleaned up metal shavings from my last assault. Inspected trim sender/limit. Yanked those out for replacement. Inspected the water intake hose. Looks okay. No cracks. One of those bolts on the inside looks really tough to get at. Maybe I'll pull it, maybe not. Pondering adding a trim position indicator. It doesn't seem right having those wires just go nowhere.

Examined where swivel pin was removed. Lower bushing area is pretty smooth. It's pretty rough where the seal was though. Maybe I should add a grease fitting to hedge my bet. Found the dimple up top. That won't be too tough. How the hell am I going to remove that top bushing? Maybe I don't need to. Think I'll have the new pin drilled out somewhere.

Outdrive, gimbal ring, bell housing, and prop are all primed. It's interesting that the B2 uses no gaskets for attaching the upper and lower units, nor to attach the whole assembly to the bell housing-just o-rings. There was some grease in there though. Was that 2-4-C? I'm going to put the two halves back together for the Trilux 33 topcoats.

I think you'll need a puller to remove the top bushing, I was going to do it but the new square shaft felt nice and snug in there so I just left it alone. it does seem like a waste having to purchase a trim indicator switch and have nothing for it to connect to. Keep us posted on the drilling of the shaft and the zerk install. Looks good all primed up.

I was originally thinking the water intake hose looked fine and I'd just leave it. Then I remembered builder dude saying something about bravoitis.

I used a chisel to knock it out. It was split and formed with a seam so once you get under it's edge it deforms and pops right out.

There was quite a glob of salty goo just inside the hose and evidence that this gasket was about to fail. It was already seeping and starting to corrode the through-hull gear oil fitting right next to it. The insert, however, shows no sign of failure.

Did you use that aftermarket fitting?

No, I ground out the corrosion and repainted (zink chromate &black) then reinstalled as it was. Once she's in the water I'll be keeping a close eye on this area and will most likely use that aftermarket fitting if the Bravoitis returns. This is what mine looked like after removing that water neck fitting, the insert was crushed and the pathway for cooling water was about the size of a pencil :pinch: . Note: most of the white dust you see outside of the area is glass dust from my grinding.

Is this as much of a problem on trailered boats that are flushed after use? I saw no build up when mine was apart 2 years ago.

PO dry stacked mine most of it life. It was moored the last 3 years before I purchased it. My theory is during maintenance or more specifically a water hose replacement at the transom/bell housing the paint gets chipped off or somewhat removed in this area from the prep process for the new hose. In comes the salt and it's only a matter of time. IMO it's something to keep an eye on during anual maintenance.
