Well, I thought I had better contribute
to the “stories” section given that I encourage
everyone who is a member to give us a brief history of
his or her beloved craft, so here we are.
We bought “Osprey” in April 1999 from a marina
in Northwich, Cheshire for a bargain price of £7500,
(far too cheap)!!
I never intended using her anywhere but
the Broads so I promptly arranged for her to be transported
to Oulton Broad at a cost of £320.00.
The first season was excellent, at that
time she had a Volvo AQ170c 6cyl petrol through a 280
outdrive leg and did we have some fun on “Breydon
Water” We are a family of four and although sometimes
a little cosy we have found the boat provides everything
we ask of her.
With the hull freshly anti-fouled and a
service done she would cruise at 20k and could reach the
dizzy heights of 25 k flat out, (not at all bad with four
people and associated belongings on board!!)
At the start of my third full season I decided
a new engine was the order of the day (there must be one
hell of a market here if only in Fairline Holidays!!)
but unlike the previous 2 re-engining stories I decided
to go Diesel and to do the conversion myself!
The engine I opted for was light, simple
and efficient a 60hp normally aspirated Ford Escort 1.8
engine of 1993 vintage,
. All the marinising parts were sourced
from Lancing Marine and ASAP supplies except for the adapter
plate for the bell housing to the engine, which I had
to have made locally from my own drawings.
Once the engine was bolted to the bell housing
I had to make supports for the engine mountings as these
were in a totally different position to what was required.
The most problematic area by far was the
exhaust system; with an out drive leg the exhaust gasses
are taken outside via the leg. Because the 1.8 diesel
engine was a totally different dimension, it meant that
the exhaust from the heat exchanger was impossible to
route to the exhaust on the out drive leg without serious
modification. (My intention had always been to do the
conversion so that should I decide to go petrol again
I could simply exchange the engine in say half a day,
to this end I have not hacked away or chopped any part
of the original installation including wiring. Etc I have
merely extended or made adaptors to suit)
Getting back to the exhaust I realised I
had only one option and this was to run the exhaust either
through the transom or out through the side of the hull.
Because I am not a great fan of drilling
holes unless absolutely necessary I ran the exhaust hose
to the starboard side outlet used for the self draining
cockpit, having replaced the plastic skin fitting with
a stainless exhaust trumpet.
Also in order to ensure sufficient drainage
for the cockpit this hose was diverted to the exhaust
via the out drive leg, so again no problem if we revert
to petrol.
The swap took around 8 hours with the boat
in the water and the diesel engine was in and running
(I had marinised the engine prior to taking it down to
the boat) There have been teething problems and a substantial
loss of performance, for example we can now only squeeze
10k out of her but on the plus side a full seasons cruising
for a mere £120.00 as opposed to £475.00 the
previous season is some saving, and on the broads especially,
10 k is almost 6mph over the limit!
At sea she is fine although we can only
make 9 knotts so we need to be choosy as to when to head
in which direction.
The total cost of the conversion was around £1300.00
including the second hand engine from a local breakers
yard.
Would I do it again????…………………………..Yes,
for my needs the economy and reliability of a diesel are
the deciding factors although as I mentioned earlier we
have had one or two problems but nothing too worrying,
If anyone out there is thinking of converting
to Diesel and would like the “Honest” version
of what is involved please let me know, I will help in
any way I can.
The magazine “Boat Mart” has
2 very useful features on converting a car or van engine
for marine use these are in Dec 2000’s issue and
Dec 2002. (A copy of which I will gladly send to anyone
interested)
