Going to be doing a sea trial on a sport fish in Fort Lauderdale. Can anyone recommend an engine mechanic for mtu motors and for a marine surveyor? Thx.

Hi, Looking at 2002 65 hatteras enclosed bridge with the Cat 3412 motors. Looking to see what the cruise and top end of that boat are? Any known issues with the boat? How does it ride in heavy seas? Anything to be aware of? Comparing it to a 2002 Viking 61 EB with MTU 12v2000s.

im looking at an early-mid 2000s 65 hatteras. i noticed some come with a lower HP Cat 3412 and others come with the MTU 16v2000. The MTU boats get up to about 40 knots and the cats low 30s. Does anyone know how much more expensive the MTU will be to maintain/rebuild? I understand that MTU is...

hi, i have a 52' sport fish and in the cockpit i have a quick connect fitting for dock water. Does anyone know what kind of fitting this is? i need to hook it up to my shore water connection, but i dont know what kind of fitting it is.

Does anyone know what part number is used for injectors on an 8v92 TA 735 HP motor are? I currently have R5235670 and i am in the process of rebuilding the motor and want to know if these are the correct injectors. These are currently the injectors in the motor, but i dont know if the previous...

i have a 52c and it's time to replace the life raft. would you guys prefer to mount the life raft on the bow next to the dingy or keep it in a movable bag placed in the cockpit for extended cruises? If the boat starts sinking i am not sure whether it would be easier to deploy from the cockpit...

Does anyone have the part number for a 8v92ta 750hp cylinder liner kit? my engine was modified by covington (they were no help) and left the detroit diesel factory as a generator or something so my serial number doesn't pull up the right cylinder kits. My starboard engine was rebuilt with...

does anyone know how many gallons is the bait tank on the a 52c? My model is 1988, but im sure the other models are also the same. I am trying to size the pump and i am not at the boat to measure how many gallons the tank is. The tank is the factory tank on the left side of the boat.

I have some play in both the rudders on my 52c. last winter i changed the ball joints and changed the bronze bushings at the steering knuckles which helped, but the there is still quite a big of play in the rudders while underway. How tight are the cutlass bearings supposed to be around the...

my hour meter on one of my engines stopped working. at first i thought it was a bad fuel pressure switch, so i ordered a new one. Just before i was about to install the switch i put the ignition in the ON position and wasn't able to get 24v at the switch. I looked at the hatteras wiring...

hi guys, one of my hour gauges have never worked since i got the boat a few years ago. Can someone tell me where the wires from the gauge run to? Are they powered when the key is in the "ON" position or when the engine is actually running?

I am changing the fuel pump on my 8v92 and the new pump sounds like something is loose or sliding around on the inside when I shake it or flip side to side. Is this normal or is something wrong with the pump?

DD powercool 3000 vs Pencool 3000 are these two the same thing? The DD stuff says "with Pencool" technology and the names are almost identical. Does pencool make the product for DD? the boat is in souther California and i want to run distilled water with the pencool additive only.

hi guys, i have a 52'c with 8v92s. i have heard many stories (as well as threads on this forum) regarding leaking exhaust risers destroying engines. However on my boat i dont see how leaking risers can do any damage? The raw water comes into the riser about 8" behind the turbo, and the risers...

What is a good assembly lube for crank shaft bearings, cam shafts etc. prior to first start after a rebuild? white lithium grease was recommended by the detroit parts shop. i have also seen sythetic assembly lubes, from companies like Redline or royal purple. Will those work better...

hi guys, i got a 52c sport fish with 8v92s. does anyone know if the oil pan can be removed with the motors in place? seems like i need another 1" of clearance to be able to remove them. Any input would be great.

here is a question for you guys; The detroit manual specifically states that the engine should be running while conducting compression tests on each cylinder. However it seems to be industry standard to conduct compression testing on diesel engines without the engine running. (just cranking)...

can leak down tests be used on larger diesel motors to help identify a low compression problem in one of the cylinders? ie, bad rings, valves not seating correctly, head gasket? I know this test is used on gas engines, but for some reason i am having trouble finding much information on it with...

i have an mdl4 with a L423 motor. Does anyone have the specs on the intake and exhaust valve specs? I am talking about the clearance between the rocker arm and the top of the valves. Any other issues to look at for tune up? the injector pump as rebuilt a few hundred hours ago.

I have a 52c and like many others here i have years and years of bottom paint accumulation. I would love to bead blast the bottom, but the problem is a have many small blisters. (quarter size) Bead blasting will obviously open them up and ill be forced to peal the bottom and re fiberglass it...
