re-powering 1988 Sabre 36?

Hopefully about to be a new owner of a 1988 Sabre 36. The Westerbeke W27A is original equipment and has over 2000 hours on it. Could be that it runs for another 1500 or more, or it could be that after 31 years it will need replacing in the couple of years. I'm hoping someone has experience and/or insight on what good replacement options might be.

Re: re-powering 1988 Sabre 36?

Don't know, the answer to your question. I haven't done that research yet. Two things come to mind though. If you are just buying the boat, I'd have someone look over the engine, test the oil, compression etc. Make sure everything is sound.

I don't want to jinx myself, but my WB 27 is 34 years old and still running strong. You may have to replace things like water pumps, Heat exchangers etc. but if the engine was well cared for it should service you well for years to come.

Re: re-powering 1988 Sabre 36?

We just retired a diesel 38 year old genset that had around 19,000 hours on it and was still running fine. Problem was with freeze plugs and the like, not the diesel engine's operation. Take care of your Westerbeke, change oil frequently, especially if you don't use it much, and keep anti-rust additive in the fresh water and you should be good to go for many years. We changed oil every 150 hours on the old genset and will on the new one as well.
2000 hours is nothing for a well maintained diesel!

Thanks. Hope we can get that kind of hours on it. Will make sure the maintenance routine is solid.

Re: re-powering 1988 Sabre 36?

These are the rules of thumb that I use for maintaining my Universal M25 diesel engine;
  • Visual inspection (belts, fluid levels, cleanliness) - 10 hours or every week.
  • Oil and Filter Change - 150 hours or every year. Whichever comes first.
  • Replace fuel filters - as needed. Minimum of 300 hours or every 2 years. Whichever comes first.
  • Coolant drain & replace - 300 hours or every 2 years. Whichever comes first.
  • Valve adjustment / check - 500 hours or every 5 years. Whichever comes first.
  • Injector pop test / cleaning - 500 hours or every 5 years. Whichever comes first.
  • Compression test - 500 hours or every 5 years. Whichever comes first.
  • Clean exhaust elbow - - 500 hours or every 5 years. Whichever comes first.
  • Starter Motor clean and lubricate - 500 hours or every 5 years. Whichever comes first.
  • Major engine rebuild (injector pump, cylinder head and cylinder deglaze) - 5,000 hours

Re: re-powering 1988 Sabre 36?

Hey,

IMHO the main killer of marine diesel engines is salt water. Assuming the engine gets basic maintenance like oil and coolant changes, it should last a very very long time. Now if you let the oil sump sit in a salt water bath, or ignore a leaking sea water pump that is dripping or spraying salt water into the block, and otherwise ignore it, the case will rot and once that happens it's not really worth it to make repairs.

I've seen an engine that was constantly exposed to salt water (the oil pan). Eventually the pan developed pin hole leaks. That allowed oil out and salt water in. That destroyed the bearings and the engine was ruined.

The Universal M25 in my 1986 O'day had about 4000 hours when I sold it in 2014. It ran very well and easily moved the boat at hull speed.

Don't forget Zincs, my Volvo has a block Zinc on a 1/2' plug on the front of the motor by the thermostat.

Good point about the sacrificial anodes. I try to check them every month. I just replaced the one in my heat exchanger anode after 3 months of use. This particular pencil anode had corroded in the middle. I guess that there was some kind of mould release agent on it that prevented it from wearing from the end.

Here's what it looked like:
