I may, or may not repower my boat. But, if I was to, where would one start
in a search for a new small diesel to repower a sailboat?

Is there a trick to finding a deal? Boat shows? I seem to remember someone
here mentioning boat show specials.

I am going to keep my eyes open for a small ( 16-20 hp ) diesel . If I see
a good deal, snatch it up. Then take my time putting in in after taking out
the old.

But, where to keep those eyes looking .. that is the question.

Boat shows can be productive. Get to know your local dealers and keep
an eye on EBAY also.

If you have a diesel, rebuild it or get a rebuilt one. Otherwise, see if
your boat had a drop-in diesel when it was built and concentrate on that
series, as making up a proper new bed is either no fun or very expensive.

A modern diesel would require replacing just about everything, which
jacks up the price.

We repowered with a Yanmar over a decade and LOVE it, but if we knew
what we know now, I'd have gotten a rebuilt Volvo MD and new prop,
saving a bunch of B.O.A.T. bucks.

At 20 HP, you're in the "Atomic 4 Replacemnt" group, which is well
populated.
Several manufacturers offer 'Atomic 4 Replacement' diesel engines. Many
are based on the same Kubota 3 cylinder block, the only difference
being the 'marinization' of the engine.
Yanmar has a similar size / weight engine which is not based on Kubota
- it's a Yanmar (!), the Vetus is a Mitsubishi, and I believe the
Volvo is a Perkins

Here's the list:

Universal M3-20B
Phasor Marine P3-20-SM
Beta Marine BD722

Yanmar 3YM20
Westerbeke 20B2 or 30B3
Vetus M 3.09
Volvo D1-20

I saw this engine at the Annapolis show, and it has some nice features

Lombardini LDW 702 M


If weight is a concern, the first 3 (the Kubota derivatives) and the
Lombardini have a
'dry' weight of around 230 lbs. The last four are closer to 290 lbs.

The Volvo is slower turning (3200 RPM vs 3600 for the rest) *and* comes
standard with a whopping 115 Amp alternator.

The cost of the basic engine + standard gear reduction (less high-end
meter/light panel or other options) is *around* 5.8 - 8.5K$US. Often
the best deals are had at boat shows, so if you're looking to save $,
enquire at a major show. This price does *not* include installation;
you get the engine on a wooden pallet.

Boat shows are good for maybe 7 to 10% discount. If you want to save some
big bucks find an industrial dealer for the brand you are interested in.
The lowest price I found for my Yanmar 4JH4 from all the "marine" repowering
companies authorized to sell in Georgia was $12,100 plus "delivery costs" of
$450 and shipping. At the Miami boat show the dealer wanted 11,200 plus
delivery costs of $400 and shipping. Accidentally working from an
industrial dealer list on the Yanmar site I contacted W.W.Williams in
Atlanta. They sell industrial tractor and stationary engines but through
their Savannah office ordered me one for $9,500 and took AMEX so I got 9500
frequent flyer points as a bonus.

A different make of engine usually means a new engine bed, perhaps
re-alignment of the shaft exit, almost certainly a new gearbox,
re-machined shaft and propeller. Controls and wiring also need to
be considered. These jobs will add up to a good percentage of your
costs, so it's worth considering a re-build of your existing
engine as one option.

If you're convinced of the need for change, then start narrowing
down the engines you'd consider by checking out all the factors
above, looking for the maximum consistency and easy adaptations.

So, starting point - what will fit?
Next, what will fit with less effort?
Then, get down to the search, bearing in mind the cost of all
those alterations . . . deals are unlikely to offset those!

I've heard nothing but good things about the Yanmars, aside from cost, and
my experience with ours certainly bears them out. At 27 years of age it
feels like one of the sweetest running pieces of machinery I've been
associated with. I certainly trust it a lot more than the engine I used to
fly behind

It would be worth having some prop calculations performed. There is no
point in putting in a 3 cylinder Yanmar (or other engine) if your prop can
only use the horsepower of 2. The 3 cylinder will be a bit smoother but the
2 cylinder, 2 blade, installation in our boat is plenty smooth. Diesels,
especially Yanmars which are a cool running engine, will give more trouble
running too lightly than at their rated continuous horsepower. After you've
paid for a cylinder you don't need, you then have the reduced maintenance
clearance and extra weight for life.

The power requirements of your Bristol should not be very different than
Strider and I have all the power I need. I was able to keep moving straight
into the wind during a squall that heeled us under bare poles to our normal
sailing angle. The sail cover was thundering and the rain hitting my face
stung. I don't think you need much more power than that unless you plan to
tow a barge.

That is a key test of sufficient power in my experience. Anything
less will give you some tense moments every once in a while.

What size boat?

Roger ,, you have a 2cyl, 2 blade? Very interesting. What is the hp of the
2cyl?

The reason I ask: I got to looking at engines on the net. Always looking,
looking, looking.. anyway,, one thing led to another and I started looking
at the BETA engines. BETA has a new diesel which is a 16hp, 2cyl. I'm not
sure what the blade requirement is.

I've always felt that many boats overpower. That isn't a bad thing if that
is what one wants but for just getting in and out ... that 16hp, 2cyl sure
did look pretty.

Fits the same general area, bed as my Atomic 4. I love the Atomic 4. It is
so simple. And with help like Mr Moyer in MD the engine will be around
forever. That said: having gallons of gasoline not far from where I am
cooking, sleeping, etc does get my attention.

I am not in a rush. This is not an emergency or anything. I just figured
I'd look, learn, and if a really great deal came along .. buy.

Tell me/us more about what engine you have in your boat. What size? HP?
Alternator? All the good stuff.
