spring maintenance

Re: incidental finding while cleaning aftercoolers

You already identified the problem.........."brass" , needs to bronze so as to not fall apart in the seawater stream.......Pat
 
Merged, and thanks to Jay for pointing this out. My computer skills are better than they were, but not equal to some others here.
 
Drove to Crisfield today and picked up my freshly cleaned aftercoolers AND had the gear coolers done also. New SS fittings in the gear coolers (bronze ones are unavailable anywhere as far as I can determine) We are due for bad weather so nothing's happening with reinstalling any of this stuff until I can flush the engines- for which I need warmer weather. So it goes.
The shop had two new M11s on the floor waiting to be picked up to go in a boat. About 3200 pounds each. Seems like a lot until you realize they made 700 hp each; and I don't know how much torque. If I had a 45C, I'd have a set of them, too.

You don't know, because it doesn't matter ;) Which is also why torque is not listed on the name plate.
 
Right, you've pointed out there's a formula to figure it out, because hp is a derived number and torque is measured. My point was that they make a great deal of torque. And that I wish I had a set of them.

Sort of...but it's more that horsepower is POWER and torque is just a force. How much torque they make is irrelevant. I can make 1000billion ft lb of torque, just give me a very long bar!
 
Progress today- got the aftercoolers back in, and the gear oil coolers. STILL waiting on phosphoric acid cleaner to flush the HEs, so nothing is hooked back up. But at least some of the work is done. And I've moved it along a bit.
 
Flushed the heat exchangers and drained them, installed new zincs, now just waiting for hoses and clamps to wrap this all up.

Seems like either the engine room shrank or I got bigger.

Why does everyone worry about s.s fitting with bronze?

Because most say you shouldn't do that but yet they put a Bronze wheel on a s.s shaft :p

Made some progress today, despite the crappy weather here- got the stbd engine all back together with (mostly) new seawater hoses and clamps, tightened everything else up and it all looks good. I still have to put the port engine back together- all the hoses and clamps etc. This requires moving all my tools etc to the other side of the engine room/salon. It's times like this I envy the folks with 53 MYs- a walk-in engine room for each engine....

Unfortunately I also have to work Friday-Sunday. Work is indeed the curse of the boating man.

Still to come- get the cover and frame off, put the SS bridge ladder back in place, and get her cleaned up and the bottom touched up. Launch was supposed to be 4/12, but I think we might miss that by a few days. But the weather is beginning to hint at getting nice, and I can't wait for boating season to begin.
 
Good progress! I haven't got crap done, due to other engagements. I think I'll splash and do the coolers and pumps in the water. Dock is closer to my tools anyway LOL.
 
Yeah, I am lucky to have a boatyard 20 minutes from my house. OTOH, they want her to go in within a week or two.....there's no emoji for lighting a fire, but the polite pressure is on.
 
Well, the boat is on the hard just down the street (1 mile), but still easier when I can walk to the tools instead of drive. My boat is parked behind 2 others right now. It's also a nicer view working on the water lol
 
Do you have a slip at your house? If so, I am envious.

I was looking at the HEs yesterday. I wish that on the B series engines, the end caps were easier to get to. It is hard to get to the bolts that hold them on. Not great packaging. Are they better on the C series? The gear coolers and aftercoolers are not difficult; the HEs, well, it could be better.
 
Not my house, but slip is near the barn with tools.

The heat exchangers are pretty easy to get to on the C series, on the starboard side.

That is far better than what the B series offers for that. I need to see if there's an easier way to get them off.

Interestingly, when C series first came out and B series only went to 250hp, at least one 36C like mine was repowered with C series. A tight fit, probably. The modern C series would twist the shafts right out of the boat.
 
the 8.3C barely fits in the 41c...I think the floor has to be raised an inch or so. I don't see how they fit at all in a 36.
 
At the time, I think they only made 350hp- far less than they do today. My guess is the engine vertical size was smaller. I remember one boat berthed in Ocean City, MD- "Notorious", I think it was, that had them. I wonder if she's still around.
 
Either the engine room of my boat got smaller, or I got bigger. Hoses and cooling system wrapped up, just a final check on everything, and tomorrow we get the cover and frame off.
 
Got a lot done, today. The flybridge ladder is back on- a huge shout out to John Kucha, welder eztraordinaire at Metalcraft Engineering in Annapolis, who not only welded in the SS treads, but kept the ladder exactly the same shape as before so it fit onto the boat and all the screw holes were able to line up. This isn't easy- the ladder is a complex shape and is not square.

Also got the cover off, folded up, and dropped off for repairs at the canvas shop; and got the bridge over, the bimini boot, and the aft awning back- cleaned, rewaterproofed, and restitched.

Now up to the yard- repaint the bottom paint as needed, new zincs, barnacle buster, and wash and wax boat, and she goes in.

I DID get photos of the ladder, and if I can ever figure out how to get pictures up again, I'll post them. I am not having any better luck than anyone else.
