Low hours older Cat 3208NA
Hey There-
I'm looking at primarily single engine boats in the 34' to 38' range, and have come across an '81 34' Californian with a Cat 3208NA that has a very low 372 hours on it, original engine according to broker. I know seals and gaskets will dry and crack from prolonged non use, but what other problems can occur in a situation like this, and what would you look for at the sea trial? Scoring of cylinder walls from moisture? Will oil turn to sludge? I've cleaned old bearings where the grease had turned to wax over the years, will engine oil do the same? Thanks- TW |
Be mindfull of coolant leaks. There is a little plastic tube with O rings that gos between the front cover and the heads that is prone to leaking. You have to pull the heads to change them and you need special tool A to remove them. or is it tool B.
If you do a search on cat 3208 coolant leak you can follow the replacement of mine. SD |
Just bought a 79 year 44 foot Atlantic with twin 3208 na. Has 4500 hours , after oil analisis and survey, mechanic said with proper maintenance could expect another 4500 hours, had all fluids changed, zincs , belts, hoses changed. Heat exchanger cleaned. Good luck

After reading your thread on the 3208 coolant leak, I have decided to stick with my current boat.....

There is DA Book from each engine builder which specifys how to preserve an engine that is out of service.
IF this was done , the engine should be fine. IF not a run to see how much it smokes at startup and how long UNDER LOAD NOT DOCKSIDE!! it takes for any smoke to depart would be wise. If the engine runs clean (no white smoke) at low coolant temps during warmup 120F ,140F the cylinder walls are probably not pitted from rust. If it takes +170F it would be time for a compression check. These engines are the cheaper version of the CAT 1160 that could be infraned, cylinders replaced. 3208 are considered throwaway engines as the block must be sent to a machine shop to renew the cylinder bores. When OK the engines will usually run for 7000- 8000 hours , and more if seldom out of use. |

You didn't say but if the 3208 has caught your attention and becomes all you are looking at, you may miss lots of other issues which are just as expensive or more so
|
Just to be clear...if a 3208na has been well cared for, it is a great engine that will provide thousands and thousands of hours of service.

Humm, 12 hours per year running time. Any idea if the owner changed the oil yearly? Sitting for 35 years in a marine environment is pretty abusive in itself. Bad hour meter maybe?

FF is right on. It's pretty easy to tell just get her running. Pull the oil filler plug and look for sludge on the bottom. The white smoke indicates a blown head gasket. Though not always.
My 3208 will occasionally smoke if I forget to cover my stack if it rains. When the stack gets hot she smokes a bit. You really have to listen to it run. Listen for knocks. How does the rest of the boat look? Ad |
Thanks All-
Thanks everyone for the info--
Skipperdude, thanks for the encouragement, my response was somewhat tongue-in-cheek, but that is one scary story, mainly because I've been there myself. But as you say, in the end you know a whole lot about your gear, and that's a very good thing. I haven't gotten down to see the boat yet, and the engine is certainly not the only thing I'm concerned with, but that was the first big red flag that came up. FF's info was particularly informative, and if I have any questions a compression test sounds good. I like the model of trawler it's in, and if the engine isn't damaged from the non use, it might work for me. Another thing I've been wondering about--if you could find a boat that was in relatively good shape but with a crapped out engine, what does a repower run, with a modern Cummins or such? Any ideas? Thanks- TW PS--I will try to find out just how the current owner took care of the boat. It's in really good condition supposedly, and the broker said he'd go down and start it frequently, just never took it out. We'll see... |

You can repower with a rebuilt 3208 for low dollars...especially because it will be a drop in. Plenty of rebuilt 3208s out there ...other than taking it out/in as a cost ...cheap to rebuild too. True they are out of production but many still in use and I have not heard of any parts shortages yet.

what does a repower run,
Depends on your skillset and EGO. If you have the ability to do all the change your self , by selecting a quality rebuilt (happily with mechanical injection ) you can lower the engine cost by 2/3 or more. Select a rebuilt common commercial tranny like a Twin Disc and save 2/3 again.. IF you can use a keel cooler dry exhaust , no seawater cooling , added heat exchanger and always dieing marine exhaust manifolds need to be bought. An out of favor with marinizers engine can be had at low cost from many junk yards . No matter what its still a load of work! Engines buried under immovable pilot houses are harder than aft under deck engines , like in a sport fish. |

Call Mr Caterpillar (Bruce (954)661-3208 , he gave me a lesson when I bought my boat. he knows everything about 3208

If the engine was nor pickeled by DA Book, for all that non use there WILL be some damage. But for many folks its meaningless . So ir coulds have been a 8,000 hour engine , but its half shot from sitting . 4.000 hours at the usual trawler 200 a year is still a lifetime. IF New it would burn little oil, but the cylinders rusted a bit so it eats a gallon every 5 hours , so? In great shape it might burn 10% less fuel per hour , so? Many of these older engines work far better , with use , and a few oil changes than one would expect. The few gal of fuel and oil extra per day would never be repaid , even with just a rebuild , never mind an engine swop. |

Hey, the engine may be fine, there are thousands of them out there. Check it out.
