Re: High thrust outboards
Jason,
Yes! All the non-electric start models (very few) start with a hand
crank on the camshaft end. This gives a 1 to 2 cranking speed and they
seem to all have some sort of automatic decompression device. They
start easy in 30C. temperatures!

Hi Chris,
You are right about the weight, I have a 3.3 Merc (Tohatsu?) weighs
about 35 lbs. I don't think it do much except make smoke and bubbles
on a barge, tho...I think I would build a box around the thing to
avoid moving parts and some noise, like many Bolger designs. I am of
the persuation that would rather put a 1 ton 1100 RPM Gardner diesel
in a boat instead of a 300 lb turbo 3600 RPM job.
'Course you would need more boat...

Jason,
I saw a 6.6HP version of this setup here in Nicaragua a few years back
at an Industrial/Agriculture fair (EXPICA). It looked big, HEAVY, and
somewhat crude. These little agriculture diesels are quit popular here
in Nicaragua and they look like a license (or outright copy) of the
Brazilian built Yanmars. They are 4 stroke even though they are
horizontal. They are loud, but not obnoxious. I got to compare side by
side a 6.6 Brazilian Yanmar (at $850) and the Chinese copy (at $650) a
few months ago. The Chinese copy was not as "finished" but seemed very
functional.
EXPICA will be held again this year July 21-31 and we plan to attend.
If I see anything interesting I will take a photo and post some
information.

PCB designed a boat around a Chinese inboard diesel engine. It's a
16' steel box-keel tugboat, with a 30 hp Hardy, described in BWAOM.
He says "I've seen only one of these engines installed, but it looks
to me, and to some better judges, like an excellent piece of
engineering."
Relevant to the discussion on Bonefish, he proposes that the tug be
built on its 1/4" steel plate keel bottom.
BTW that link didn't work for me.

Good question!
I think there is a geared crank on the starboard side. The crank
handle may be wide enough for two hands. What about the little Saabs?
They hand-start in Norway. I guess preheating may be unnecessary in
Thailand, but Minnesota...I will ask.
I was in Japan a while ago, and in the boondocks lots of farmers use
a single-cylinder diesel by Yanmar that I assume is the origin of
that engine. They power lots of heavy farm trucks by belt drive by
pulling the hood, motor and radiator, and propping that little red
putter in a shelf on the firewall. They are not obnoxious in the
Yanmar version, but the trucks appear stay in first gear...It does
get Cold there, too, so the cold start is overcome somehow. Many of
those are starter motor equipped, so maybe they have a glow plug.
Since the thing seems to lay on its side, I guess it is a two stroke.
I would love to buy one too. It would be a good shantyboat motor, my
next project, I think.

It has been discussed, but not to my recollection by anybody
who has actually used one. My guess is that it would be
temperamental to get started, and also it might be
quite noisy. I would love it if you bought one, tried it out and wrote
an online review.
How would you start that diesel?
I presume it does not have a glow plug,
...preheating with a blowtorch on the cylinder head?
Here is what I think may be the ultimate Lo-HP Hi-thrust powerhead:

Yamaha makes a 10HP diesel (not imported to USA), but it is more
pricy. Also Higher RPMs and smaller prop. You could buy this diesel
and enuf spares to last forever for cheap.
(my first post) sorry if I missed previous discussion of this
technology...

Shame on me for not looking up the Tohatsu and Suzuki. I do have brochures
for Merc, Yamaha, and Honda at the ready though.
I had a Merc 15 that was all Tohatsu though, and it was a good motor.

I hate to correct someone whose opinions I value as much as I do John
Bell's, but the 4-stroke Tohatsu 25 is a 3-cylinder motor, as is the
Honda 25 and the grotesquely heavy Suzuki/Johnson 25. Only Yamaha and
Mercury seem to offer 2-cyl 25 hp 4-strokes right now.
Merc has been using Yamaha powerheads with Merc components on many
4-strokes, but their <20 hp models have been Tohatsu from one end to
the other for quite some time (sometimes with a few bells, whistles or
enhancements that Tohatsu doesn't offer on their own models). If
they're going with a Tohatsu powerhead on the new 25 (which would seem
sensible for them to do since they've bitten Yamaha's feeding hand so
hard), it wouldn't surprise me if they went with the entire Tohatsu
motor and either abandoned the 'high-thrust' model or convinced
Tohatsu to develop one.
FWIW, I own a Tohatsu 8 hp 4-stroke 2-cylinder motor, and have run the
older Honda 7.5's and 10's (also 2-cylinder 4-strokes). They are
relatively quiet, but they shake like giant 1-cylinder 2-strokes
because the pistons go up and down in unison and you only get one
power pulse per revolution. The 3-cylinder models seem smoother, but
tend to be heavier, which can be a problem in some applications. I've
been told that the Yamaha/Merc 25 does not shake as bad as some, but
have no first-hand experience with it and can find nothing written
about its employing special smoothing technologies like balance
shafts. I personally would not buy a larger 2-cylinder 4-stroke
without a chance to test-drive one first.

When Phil added the double bottom this is what he recommended if you planned
on low planning speeds instead of displacement speeds. Even though I will
probably spend most of my time at lower speeds, I would rather listen to a 25 at
2500rpm than a 9.9 at 4500rpm.
I will have to recheck Honda. No dealer informed me of an added 25 high
thrust. As far as local dealers, I am planning on towing this from MN to FL to the
San Juan's, and many other places.

I am not sure I can be much help, but for what its
worth I have a high thrust Yamaha 50 horse (T-50) four
stroke. I bought it on Phil Bolger's recommendation,
and had to swallow hard, twice, once as an old
Evinrude guy, and once at the price. I have since run
it hundreds of hours. I would rank it up there with
my mother's '45 Singer portable sewing machine and my
secondhand (1960) craftsman jig saw as one of the
finest pieces of mechanical gear I have ever owned
(God help me, I am starting to sound like Robb White).
Starts, idles, runs, easy on gas, quiet, no problems.
I also have experience with Suzukis, but only the
two-stokes. Nice engines, but not as reliable as my
T-50. Sam

I was under the impression that high thrust motors were for heavier
displacement and semi-displacement boats running at S/L's of 2 or less. Why
do you need high thrust for Bantam? (I'm not saying you don't, I'm genuinely
curious.)
Comparing the small Tohatsu to a 25 HP motor isn't really fair. The Tohatsu,
Merc, and Yammie 25's are all two cylinder motors Honda even has a 3 cyl 25
on the market this year. Everything less than about 8 HP are all single
cylinders, which was probably the case with your friend's Tohatsu. Any
single cylinder motor will have a lot more vibration than a multi-cylinder
engine.
My personal pick would be to buy the motor that you can get the best price
for as well as one that has the best service and parts network in you area.
WRT to parts and service, in most places Mercury > = Yamaha = Honda >>
Suzuki.
I'd buy a Mercury myself. (Although, I've got a friend who is on the verge
of becoming a full line Honda dealer, so a BF5 may be in my future.)

a smooth motor, vibrates a lot. Both Mercury and Yamaha have 2.42 to 1 hear
ratios with a range of 5500 to 6000 rpm and 30.4 cu inches. The Yamaha only
has a 2.09 to 1 ratio, but at 36.4 cu inches running at 4700 to 5300 rpm. At
$4000.00 one does not want to flip a coin. I have done a search for motor
reviews, but cannot find any, except on OB's over 100 HP. Does anyone have any
knowledge of motor reviews on these, or any experience with them? Thanks!

Tohatsu powerhead. I have a friend with a smaller 4 stroke Tohatsu and it is not
