Thank you Chrijs, I will find similar product in my country.

It could be steam since I am also in a humid climate, but also since big temperature difference it is a "good" spot for condensation anyway. Can you recommend/link some brand or type of fireproof cement, never heard of it, so I can see what exactly is it?

A couple of questions about the exhaust wrap (of glass fibers). I have done it with the wrap on my risers and wrapped it enough until I could touch the surface of the wrap while at running temperatures (made it in two steps). Now, I am running the engine mostly at slower speeds, not planing...

Now, that is an answer Steve and I like it, thank you. Those definitions have removed any doubts about what type of pump is it. Truth, I have found centrifugal pumps with side channel for priming, so that is what Gilkes is talking about in brochure and manual, but not in details. And, yes I know...

Thank you Steve. I was just curious, not against rubber impeller pumps, so basically compactness could be the main reason, since both can be implemented with pulley or gear. Are you sure 100/350 is centrifugal pump (self priming is obvious)? I am confused since in original Gilkes brochure for M...

The principal is the same as Nash liquid ring pump (don't know the difference between compressor and vacuum pump in this case), same pump can be used for gasses or liquids because after you add enough liquid to the pump on initial start (prime it) to fill enclosure around the vanes (form that...

During the restoration/renovation planning of my boat, long time ago, my father has chosen not to use original impeller pump for Cummins V-504-M, but rather liquid ring pump Gilkes M 100/350 which was available at that time (in the '80s). Since I have continued restoration/renovation in recent...

Thanks FF!! Haven't thought of it that way. Than I would not touch anything except following servicing routines and oils/filters change intervals according to mfg specs. And yes, there is smoke only during transition at the worst hull angle, otherwise no smoke at all.

Is it normal for older Cummins V-504-M engine to have a bit of blue smoke under the heaviest load (transition to planning), before that and after that, no smoke at all. I was expecting more of a black smoke in such conditions, but it seems to me that it is more blue (oil) than black. Boat is...

djmarchand: Thanks for great advices! Engine seacock is for 2" hose so probably it has drain fitting, but I do not remember so I will see that today. Smaller head seacock is not so accesible to me (to put my head above it) to do something as you said, but I get the concept so I will find...

Well, this would be my first winter inside water so I have a question. I have integrated two valves before the strainer input so I can choose to use the water from seacock or internal connection on which I can attach the hose and put it in the bucket/barrel/bilge or whatever. I did that...

AusCan, that would be professional deformation since I am an electronic engineer, probably. About the no cost successful outcome - priceless. BruceK, yes, same here, just when I went through restoration/renovation process costs were all around and above my head, so every cent was important at...

DonF, new welcome. Sunchaser, well I borrowed one when I needed it, but yes, very useful tool to have, thanks. Brooksi, I agree with that, and I do "warm up" procedure during cruising, not at the dock, at the dock only until I untie the lines. At the dock engine stays on at idle a bit longer...

I waited for the weekend to do the tests, so I have results from yesterday. It was probably the oily goo since after a few minutes at that throttle smoke has cleared up. Since it is a bit colder here I had to warm up the engine for longer period, so I did that gradually as I always do, but...

OK, I here you about low power break in. Jetstream, I will do that test, good point, but if that is only due to low oil pressure then I am not sure about it because my oil pressure is as at its maximum until the oil doesn't reach its working temperature and then it varies between 40psi and...

Thank you. I would try boatdiesel.com, but for a couple of months I only get blank page after login page, from two different computers and using different browsers!? That is why I tried here. You have at least comforted me that it is not very probable to be blowby or crank bearings. Ski, I...

I hope there is still here someone experienced with this old type of engine so it can give me some light on my problem. I have rebuilt this engine (Cummins V-504-M 195HP/3000RPM) and it serves me very well. Now I have about 135 hours of operation. Thing is that I am not driving it hard, most...

Thank you very much for the welcome and for the response. I will try putting mechanical one in mainline port, I would have done that already, but fittings are different, so I have to find or build the adapter first or find the mechanical gauge that fits for test purposes. I must say that I...

Where exactly am I supposed to connect the pressure sender? On the diagram in the service manual, there are three ports, and I have attached the mentioned diagram here. One port for the oil to the cooler outlet, one for the mainline pressure tap and one for reverse clutch pressure tap. So I have...
