1393.0. "Inboard Westerbeke, 2-Cycle?" by MEMORY::LAZGIN () Fri Nov 17 1989 08:04

    I would like some information about the Westerbeke Vire
    inboard, 2-cycle, gas engine.  
    
    Is this engine reliable?   If so, why arn't they more popular?
    
    The 2-cycle engine has far less moving parts that the 4-cycle,
    and should be cheaper to overhaul and maintain...right?
    
    Comments,

1393.1but, but, but ....MSCSSE::BERENSAlan BerensFri Nov 17 1989 09:0728
Our C&C 26 had a Westerbeke Vire inboard engine. It primary virtue was that it 
was an inboard. In the two and a half years we owned the boat the engine was 
quite reliable -- I replaced the sparkplug a couple of times and it always 
ran when asked to. But ........

It is a gasoline engine. Diesels are (IMHO) much safer and far preferable.

The Vire lacks horsepower -- I think its rating of 7 hp is optimistic (or else 
they have very small horses in whichever of the Scandinavian countries where 
the engine is made -- Westerbeke is/was the importer). 

The engine has terrible fuel economy. Our C&C came with a 6 gallon tank and we 
soon bought a second. My recollection is that we were always filling a tank. 

The engine has a combination starter motor/generator. This contraption would 
start the engine reasonably well, but it wouldn't charge a battery in any time
less than eternity. We developed our habits of electrical conservation quickly. 
Fortunately, the engine can be started with a pull rope. I had nearly 
finished designing the brackets to add a real alternator to the engine when we 
sold the boat. 

The engine is seawater cooled, so long-term reliability is questionable. Parts 
are, I suppose, available from Westerbeke, but the prices are probably 
outrageous is not higher. 

I wouldn't not buy a boat because is has a Vire, but I'd be sure I could 
afford to replace it.

    I have not owned a Westerbeke/Vire engine.  I have owned a Westerbeke/
    Petter engine.  In a nut shell, parts were impossible to obtain!
    Westerbeke had many parts including the transmission and engine
    mounts, made especially for this imported engine, then ceased stocking
    the parts.  In the 25' and under category It's an outboard or a
    Yanmar diesel for me!

    On the other hand I once owned a Vire ( made in Finland) for 10 years
    and only replaced points (every year) and once took the head off to
    replace piston rings and decarbonize. Oh, and also replaced the voltage
    regulator/gen-engine xfer switch. Other than that no problems. I did
    try to replace the rod big-end bearings (not necessary but had it
    apart..) but impossible (!) since the conn rod was let into the
    flywheel using liquid nitrogen (to shrink the pin..). At 6hp it was
    fine for a small (22' wl) sail.

1393.4VIRE 7 -- 13 years and still ticking...DECWET::TARDIFFIt's all rock-and-roll to him.Mon Nov 20 1989 21:3414
...but just barely.

I have a C&C 25' with the VIRE 7, and everything Alan says about the engine
is true, especially re the low horsepower and the rotten starter/alternator.
Mine was taken good care of and overhauled two years ago, but it's not
going to last much longer.  Its only two redeeming features are its size
and that manual start.  The latter is valuable because the starter/gen
does such a lousy job of keeping my battery charged...

When I price replacement engines, though, I shudder, and pray for 50
more hours out of the VIRE 7...
