Wow, thanks for the replies,
I will post a pic of this system I have afterwards.
OK, I really only have about 3 ft lift over a length of 12 ft back to the stern. the vetus water muffler is well below the engine, I would say the top is of the muffler is at the bottom of the oilpan.
"Also, do you have a vented loop on the connection from the engine to exhaust elbow
? If not you can siphon water into the engine past the cooling pump impeller."
NO I don't see any vent if you are talking about one on the water line that leads from the heat exchanger
and dumps into the exhaust... its a straight shot in...
The muffler exhaust system used IS Highlited in the manual BUT in the diagram that is highlited there appears to be a vent that is on top of the 6" tall loop for the raw water between the outlet of the exchanger and where it enters the exhaust... this IS NOT how mine is plumbed,.. its a straight 3 inch shot out of the exchanger and into the exhaust manifold.. not a raised loop, no vent...PROBLEM????
My raw water pump
is mounted on the front of the engine and is run by a shaft with a drip area inbetween, there is no way water can get in via the raw pump.
I think you are right and I sent the fresh water into the engine so that is a different dumb thing I did.
I got very bad news this morning from the machine shop, the EXHAUST PORTS are very eaten up, so are the exhaust valve stems.
He says it looks like salt
water was laying in there for a long time after she was stored....
His boss won't allow him to reassemble it for me to run because of the liability.
He said it pressure tests OK and it is not warped but its a guess on how long it will last. He said IF I HAVE TO RUN IT,..... I will need to lap the valves because the mating surfaces are still decent.
The valves were moving freely when I was cranking the engine but if one breaks while running, I think it will destroy the lower end. This engine does not have sleeves and a set of oversized pistons are $1200.
I'm guessing that this is the same problem that eventually killed the old engine.
I have a 4 inch thick book with absolutely every reciept and manual for every item down to toggle switches and diagrams and wiring
harness, and letters to MFG's and replies and on and on.
The muffler exhaust sysem used is Hightlited in the manual and the fellow was a very thorough person, he checked most things to the Nth before proceeding, even sending patch test materials to labs for analysis before using products.
Although he obviously missed something here or something broke down somewhere.
The lower end is OK, I pulled the engine in the boat via a proper lift the owner built in and honed the cylinders , cleaned every thing and reassembled,.. its back in place and ready to reassemble,...HA HA now!
I am in a Jam on the boat as the yard wants it moved, that was part of the deal when buying
,.. not to mention its at the most expensive" YACHT YARD"
on the east coast
... lucky me, and she's not in the work area either... lol
I was trying to get her mobile so I can take her ten miles down the coast to a "BOAT YARD" that is more work friendly and 1/4 the cost to do the other repairs
..... after 200 minutes of cell calls I finally found a head gasket
and had it sent from california
overnite... it should be here today just in time to get the dead head back...
I hate to risk running this head, waste a $150 gasket, all this work then destroy a jug or two ta boot, options are slim though.
Not to mention now there is still this raw water issue getting back into the exhaust ports. That IS whats going on I think.
Anyone got a decent used head handy, ...built by AMC, for vetus in Holland
for a rarely imported french peugeot diesel, LOL
Just in case I'm gonna post an ad for a head for a used cylinder head for a Vetus P4.25... and hope for the best.
Still gotta figure out this raw water thing that vented loop???
