Hi Rami,

Why don't you consider marinising a road vehicle engine, I marinised a Ford
1600 diesel about 6 years ago and installed it in my 26 ft Westerly, it has
proved to be reliable,economical, smooth runnuing and producing plenty of
power when needed.

Also worth considering is that spares for road vehicle engine are very much
cheaper, and more easilly obtained than they are for engines specificaly
manufactured for marine usage.

Good luck with your search.

Please inform us concerning thrust bearings in such an application.

What did you do wrt the reversing gear / transmission?

Did you need to modify starter or alternator for fire suppression?

Thank you

Marinising parts for some automotive engines are available from ASAP
supplies and other sources. e.g. Exhaust manifold, mounting plates etc.

The thrust is normally taken by the gearbox bearings, so it is only a
question of ensuring the monts used are suitable or to mount it directly to
the beds.

Adaptor plates to a the marine gearbox to the flywheel housing may also be
available or can be fabricated. If you were hard up against cost you could
fit a thrust block onto the shaft and use a rear wheel drive automotive box
(how you fit a coupling flange I have no idea) and only use first and
reverse. This will give a reduction of between 3 & 4 : 1

The flywheel should have an extra weighted ring fitted in most cases to
compensate for the loss of the clutch pressure plate and to help smooth the
tickover when under power, but this is often ignored. Gearbox drive plates
for bolting to the flywheel are also available.

As most alternators and starters on modern engines are in fact earth return
ones with an added earth post, the originals can be used - in any case it is
likely that a negative ground will be needed for any glow plugs and engine
instrumentation.

It is probably marginally easier to marinise one to dry exhaust with
keel/tank cooling to save complications with driving a Jabsco pump, but
again, adaptors may be available.

If the boat needs BSS compliance all plastic fuel parts and pipes will need
changing to metal or a written statement obtained regarding fire resistance
(from April).

I have done tens of BMC diesels in my time, but nothing would persuade me to
use an elastic band timed automotive unit - better look for a more
conventional industrial engine and marinise that.

Once you start to add up the costs a reputable recon unit begins to look
better value, but I would be looking in the linage adds of "Boats under
£20000".
