Engine replacement

BCC Forum
1

My BCC (hull #64; launched in 1983) has its original raw-water cooled
engine, a Volvo MD7B. The engine still runs well, but is prone to running
hot and is underpowered (about 17 HP) such that I am able to achieve a
maximum speed of just over 4 knots in ideal conditions (i.e., flat seas and
tailwind).

As a result, I am considering repowering with a Betamarine BD1005 engine (a
28 HP marinized Kubota engine). I have heard many positive comments about
these engines. Does anyone have any firsthand experience with these engines
or comments on them?

On a 2nd and related matter, my BCC currently has the original fuel tank
installed by the Sam L. Morse Company (which I believe is either 28 or 32
gallons). I am considering installing a larger fuel tank at the same time
as I replace the engine.

Does anyone have a larger fuel tank installed in the standard SLM configured
BCC? If so, what is its capacity?

Gary,
I had that engine in a Contessa 32. It gave me quite a lot of problems
and there was no one to fix them. I ultimately found a dealer in North
Carolina who was sympathetic but not very helpful. If it was my boat
I’d stick with either Yanmar or Westerbeke. Lots of dealers,repair
persons and parts. It’s true that Beta uses Kubota but many of the
tractor parts don’t fit the marinized version. I had to replace the
flywheel because it was undersized and the engine kept stalling at low
speed. It took months to get the part.
The large tank holds 37 gallons. actually I believe that it is a second
tank below the primary.

Jim Hiller

Hi Gary-

 

No comment on the engine (ours is the original hand-cranked Sabb, 10 hp dont even mention underpowered!) but my two cents on fuel capacity . . .

 

If it is a choice between fuel and water, I would vote for water every time.  (I dont know if yours is a choice).  Our fuel tank is 10 gallons we carry an extra 15 on deck in jerry cans but our water capacity is just under 100 gallons.  Granted, we use less fuel for motoring than the average bear, with our engine, but in our three years of cruising the Bahamas and the Caribbean we were only worried about fuel once in the Gulf ICW at the start of our trip.  Water we NEVER bought those 100 gallons lasted us 6 weeks and we managed to find cisterns or get a passing rain shower when we needed it.

 

Of course, required fuel capacity depends on your cruising grounds and style, electricity requirements and desires, but we sailed into and out of some tight spots (which our boats do with ease) in all kinds of air our water capacity allowed us to stay some pretty great spots for quite a while.

 

A sidebar, to be sure, and one that has been covered in these pages before.  Still worth mentioning.

 

Cheers,

Nica

Calypso, BCC #6

Jim:

Thanks for your response (also thanks to the others that responded). Jim,
were your problems with the BD1005 restricted to the inappropriately sized
flywheel, or did you have other problems as well? If so, I would appreciate
hearing about the other problems, either here or directly at my email
dioscouri@hotmail.com .

Thanks again!

Gary,
I did have some other problems. All were a result of a poor job of
marinizing. I think that the base Kubota is ok it was the English add ons
that were problematic. There were compression problems as well as water pump
problems. Ultimately they were sorted out but the engine never did work
well. It loaded up and tended to overheat under load and frequently stalled
when throttled back
Why are you intrigued with the engine ?
Surely you know that Yanmar and Westerbeke are easier to have serviced and
have far more ease of parts access.
