Westerbeke 33

I have a westerbeke 33 in my Cs-36, the engine as around 1500 hours on it.

The engine is running great, i have used it alot in 2 years for long period of time and it always run well.

The problem.

Engine is taking some oil and its smoking a bit. Is 1500 hours alot since i am planning to go south next fall and i would like to have a engine i can trust for the trip ?

I dont know much about mechanic so i dont know if i need a rebuilt or ?

Thanks for the help.

Mike.

Re: Westerbeke 33

1500 hours, (if indeed that's a true number - always hard to know with a 20/30-something year old boat) is not a lot, but if the boat sat unused for a long time it may have suffered for it.

Smoking and losing oil is a sign that the oil rings are not in great shape, or 'stuck' in the lands and not sealing properly. I think there are treatments like 'Seafoam' that may be worth a try, but at the end of the day a rebuild could be in order, if only for long term peace of mind - esp if you're not mechanically inclined yourself and heading to areas where qualified help is going to be hard to find.

Re: Westerbeke 33

Thanks Faster, i was thinking of a rebuilt as well but i did some research in old post and the price was just crazy. Seems like westerbeke part are really expensive. i guess i will have to do some phone calls see what they say price wise.

Re: Westerbeke 33

FWIW, having paid to rebuild this engine (the w-33) once in a 36T, it is certainly crazy expensive to do. I now have a Yanmar in my P31-2, which is a much more satisfactory engine. Should you face this, if one is planning on keeping the boat, I would pay the extra to switch to Yanmar versus ever doing a Westerbeke rebuild.

Certified...in several regards...

SF.. when did that happen? (the boat change?.. missed that!)

Re: Westerbeke 33

Hey,

How much oil is the engine using? There's a big difference between an engine that uses 1 qt in 20 hours vs 1 qt in 2 hours. What type and weight of oil are you using? If it's synthetic, many older engines do tend to leak when synthetic oil is used.

Lastly, 1500 hours is NOT many hours. My engine has close to 4000 and runs great.

Good luck,
Barry

Re: Westerbeke 33

When you say qt i suppose you mean a 1/4 of a gallon ?
From what i remember doing 20 hours on engine none stop would take about 1.5 to 2 litres of oil. I did double check today and engine hours says 1300, and its working as well. As what type of oil i use its shell rotella.

Thanks.

Re: Westerbeke 33

Hello,

Yes, when I wrote qt I meant quart or 1/4 gallon (or litre, they are close enough).

Rotella is a good oil. Do you know what weight, like 30, or 10W40 or 20W50?

If it were my engine I would run 10W40 weight oil. I would monitor the oil usage carefully, checking every 5 hours and seeing when I needed to add a litre. IMHO, 1 litre every 20 hours isn't excessive, 1 litre every 10 hours would make me nervous.

Again, IMHO, if the oil usage stays steady I would not worry.

Barry

Re: Westerbeke 33

10W40 is what i am gonna use from now on,tho i dident get the chance to see what i am using atm. 1 litre for 10 hours is pretty close of what i am using right now. I guess it will have to do since a rebuilt seems lot more then 3000 $(was my budget for that )

Thanks barry.

Re: Westerbeke 33

I think it depends on how long of range you plan on going. If you are going where spares may not be available then I would rebuild/replace, otherwise just pack a lot of oil! I would make sure you are not using Rotella T6, very good oil but it is synthetic and might slip past the rings and valve seals quicker. Stick to standard Rotella for a motor that is burning.

The real issue is that if the valve seals are the cause and it gets bad enough you can run into a runaway situation, where it pulls the motor oil past the seals and burns it instead of diesel. Then you have no control over the motor and it can burn itself up or seize. It does not sound like you are in that territory, but it would not hurt to start saving the boat bucks.

You can save some money on parts if you find out who actually made the motor, Westerbeke does not actually make motors but buys industrial motors from people like Mazda, BMC/Leyland, Mitsubishi and then adapts them for marine use. I believe the 33 is a L3E block by Mitsubishi. Most of the internals are the same. You may be able to get a better deal by finding a Mitsu industrial machine company to do the rebuild.
