Anyone use a polyethylene tank???

scenarioL113

If tank is going to be constructed from Stainless Steel can anybody recommend what gauge or thickness the stainless should be?

scenarioL113

Is there anyone out there that can re-line the tank with some sort of barrier resin or something along those lines. I figured if I removed the tank and cut the top off it could be cleaned of all gelcoat (which will come off VERY easily in this case). Then the inside could be coated with something th...

scenarioL113

I am in agreement that things are bad!

Very disgusted to say the least. I guess I will have to fabricate a new one myself. Prob Stainless Steel.

scenarioL113

I pulled the plate out that has the sending unit attached to it, I am fitting my return lines into it. I noticed the fuel in there is greenish in color, it is OLD GASOLINE. The gasoline in there is PRE-ETHANOL. I have noticed the gel-coat on the inside of the tank is peeling off all over the place. ...

I was fishing in Montauk last week and the mate suggested them as well.

They are in Bellport on Montauk Highway between Station rd and Rt 112, closer to Station rd.

I actually drove past them today and was gonna stop in but did not have time. I need a quote on a pair of shafts.

scenarioL113

I am in the process of my Cummins 4BT to B28 project.

I have noticed the fuel line barb that goes into the fuel lift pump is a different size on each engine. One is a 3/8 and the other is smaller like 1/4 or 5/16...not sure but NOTICEABLY smaller.

I was planning to make BOTH 3/8.

Is 3/8 OK?

The wire that goes to the "run" solenoid that is screwed into the bottom of the IP gets 12volts, correct? I am a little confused with what was mentioned above. I am wondering if I am misunderstanding about the 2 different wires which were mentioned, 1 of them giving more amps than the other and caus...

I wanted to share some info with anyone that may be rebuilding their turbo on their Cummins engine. I have holset H1C and it was in bad shape. The shaft wheel fins (turbine side) were bent over slightly and there was excessive play in the shaft as well. I needed to replace the turbine/shaft wheel as...

This debate always comes up. RED stuff is OK on the water. The RED stuff is really the only good diesel out there. RED stuff is USUALLY RED Dyed "LOW SULFUR DIESEL" which has no more than 500 parts per million content of sulfur. The sulfur is the so called bad stuff for emissions but it keeps our di...

50 gallons usually is the minimum. I work part time for a fuel oil / diesel company myself on Long Island. I can help any of our members out with #2 diesel for your boats if your in our area. (Between say Massapequa and Bay Shore). The more you buy the bigger discount you get. We do boats usually at...

scenarioL113

Sounds like it is drawing more amps than the circuit is rated at.

Try hooking it up to a non-GFIC outlet and see if it trips the breaker in the house when you turn it on.

If it does not then try another way to ground that green wire.

Hopefully someone with more knowledge will chime in.

scenarioL113

Finally!

Someone has really invented a "better mousetrap".

scenarioL113

I want to go thru my wiring on my boat and it is satisfactory. Since I have converted to diesel I need to make my own harness for the engines, since the engines did not come with them. I have harnesses coming from my flybridge and have all of them labeled for their respective functions. I know the i...

I want to pressure test a new oil cooler I have to see if it can be used with a Hurth Transmission.

It needs to be tested to 350PSI I believe and if that is the case I was wondering if anyone knows a place in the Long Island or NYC area?

scenarioL113

I have the volume 1 and volume 2 Cummins maintenance manuals. They are real thick and green in color. They only show the configurations for industrial and automotive, the heat exchanger cooled engine diagram does not show front of engine. I bought those manuals direct from Cummins and thought they w...

Thanks!

a picture is worth a thousand words!

I was wondering what the correct path for the serpentine belt is on the front of a B-series Cummins. I am only turning the water pump, alternator, crankshaft, and the tensioner. It seems the belt rides on one of the pulleys with the grooves facing the flat idler pulley. Is there a diagram of how it ...

Are wet exhaust manifold repairable?

I have one that has a crack on the top that was only seen when it was boiled out at the machine shop.

My intention is to throw it away but before I do I was wondering if anyone has successfully repaired one.

It is a B-series cummins 4 cylinder

Just kidding but they were that about 10 years ago!

Harry was correct! THANK YOU!!!! The info gave me a place to look once the oil pan was dropped. Instead of ordering a new gasket we had an extra flange gasket. We put the "extra" flange gasket on the area that the oil pan should have covered. Fired it up and oil pressure was instantaneous! I feel go...

Harry

Looks like you were right

dont have time tyo talk now but will give full report by sunday night.

We did drop pan and yes that area was void of gasket material.

scenarioL113

I did not drop the pan yet will do it either this afternoon or if not Sunday, I have to go in for a 24hr shift in about 2 hrs so.....

When I get it off I will post results as asap

scenarioL113

Well that is very possible and unfortunately I dont recall but will know as soon as we drop the pan. on another note: When I sent the block out to the machine shop, is it possible there may be some kind of plug or galley plug that they could have removed and we overlooked when re-assembling. We dont...

scenarioL113

We checked the cooler and the gasket we are using is not covering any of the holes which may block the passage of the oil. The oil pan gasket was ordered from Cummins by the CPL but that does not mean it is the right one, are you saying it (the oil pan gasket) is possibly too thick or not allowing t...

scenarioL113

Thanks!

I have a bigger priority right now with my lack of oil pressure on my starboard engine.

Thanks again.

scenarioL113

Yes block was boiled out at machine shop from very reputable guy we been using for 35 years. The passage ways for the oil are all clear, we packed the oil pump with grease, and also with only motor oil, and a little of both. The oil pump is not pumping the oil from the crankcase, as if it can not ge...

scenarioL113

Not such a good day! Worked all day and we noticed right off the bat we were not gettting oil pressure when cranking. We checked the pump, the oil cooler assembly and many other things and came up with noting! We switched the oil pump with the other one I have from the port engine and no difference....

I am gonna start one of my 4BT's for the first time after a fresh rebuild. The head was redone when it was out as well. Is there anything I should beware of or do to make sure it goes well. Here is what I have done so far: 1st off there is oil in the crankcase and ATF in the tranny's and filters are...

scenarioL113

Guys I really appreciate the input and have read them over a few times. The info is great and a few pics would help a ton. They are explained very thorough but my comprehension is not matching. I will have to raise the hatches and the center section as well. I just may have her ready be the fall run.

scenarioL113

Yes I agree, the one on the left with little holes is a factory elbow.

I have a brand new one in my garage if you want me to post a picture.

scenarioL113

Thanks Preston! I just spent the last 3 weekends fabricating mounting hardware for my 4BT's. The mounts are overkill but I know these engines shake a lot at idle and low speed. It was a lot of work, welding, cutting, grinding, drilling etc, etc, etc! I can now order my shafts and stuffing boxes whic...

scenarioL113

Does anyone have any pictures of modified engine hatch covers on a B28?

Thanks

Frank

scenarioL113

I am hoping for an economical 21 to 22 knots. If I get that I will be very happy, if its only 19 or 20 that will be ok as well I am no speed monger!

I would really like to see a few pics of any mods to the hatches.

scenarioL113

I am right smack in the middle of the same conversion. B28 Cummins 4BT3.9m 155HP. We have spent considerable time fabricating and welding brackets to allow for mounting and have made custom trunnion style hardware to mate up to the mounts. The original v8 gassers were just lag srewed down into the s...

scenarioL113

On a further look the frame is actually two separate frames, one for front and other for back.

The one I used was a square frame which would not allow this to happen. You can still lose the boat off any set-up but this one IMHO is an accident waiting to happen.

scenarioL113

Hard to tell, I have rigged many boats on a crane and frame sling setup and that is what we always fear. Hard to tell what happened, it almost looks like the forward sling got hung up on something that was out of view. Notice how that forward sling starts to slant and then the weight shifts and "IT"...

My stringers were redone within the last 10 years and are solid. What should I do additionally for the diesel installation. I dont think there is all that much a difference in the weight from the V-8's I had in there considering I lost the velvet drives for the aluminum cased Hurth's. These are 4 cy...

I will be running red stuff, so I know what I need now. 30 microns.

Thanks for the input gentlemen.

scenarioL113

I have to agree about the single filter issue taking down BOTH engines and I will NOT do it. On a side note, I can run these dual filters separately and off separate pick-ups and install the 1 micron filter in each of them. The housings are identical and they both have a drain on the bottom of them ...

scenarioL113

I am reviving this thread with a few more questions. Since I only have one tank, Can I run 1 (one) primary filter and split off for each engine? How many microns should the PRIMARY be? 25-30??? Can the primary be a water separator as well or they dont come like that. I ask only because a friend of m...

I think my twinscan tach's will work. If they dont I will send you a message, if you still have them.

I used that or a very similar product about 10 years ago. I bought it at the Jacob-Javets show. It is NO GOOD! That is my informed opinion but it does like the others have mentioned. It will give a great shine. After a season or two it starts to wear away and you are left with splotchy patches of sh...

I found an online manual for the twinscan tachometers

http://floscan.com/html/Manuals/TwinScanTach.pdf

I guess I will set them at one of these:

50 RPM synchronized resolution - RED switch = B BLACK switch = 6
20 RPM synchronized resolution - RED switch = B BLACK switch = E

scenarioL113

You think the twinscans tach's may work?

How would the flywheel tooth count be calibrated, it has been a while since I looked at the rear of the twinscans. Do they have a calibration dial???

I appreciate the input

scenarioL113

Thank you Viceroy.

I actually dont have tachometers yet, these engines are a new install for this boat. Zero hour rebuilds.

I had twinscan tachometer setup for the gassers and figure I need to get new tachs.
