I hired a canal boat which had an Isuzu 42hp, (or maybe kW) it looked like a spiffing engine, anyone come across one at work?

very common inland i believe ( Green Engines) designed for canal use.
Isuzu engines are used in small trucks / vans in the UK , Vauxhall i think

In Saab, and the Ford 1 ton truck, but the boat had a dedicated marine engine, not a road engine conversion.

i looked at them prior to fitting a Nanni, thinking of the re-sale of an unknown engine.

Like most modern "marine" engines it is an industrial engine used in other applications such as construction equipment, refrigeration plants etc. as sailorman says has a good hold on inland waterways, perhaps because that is what the importer specialises in. a few have escaped into other markets - think Caer Ufa who posts here has one in a Colvic Watson.

A well known producer of diesel trucks and industrial engines - not as widely distributed as Mitsubishi. I was under the impression that they relied on others for marinisation (I believe the Vetus range are Isuzu-based).

A mate has 120hp Turbo Diesel Isuzu in a power boat .It's badged as Mmercruiser but says Isuzu on the tin. But he says it's the same as the old Astra 1.7D.

Yes I have one aboard my CW 23'-6" a 27.5 hp Isuzu 3KC, excellant diesel engine which only uses 1 litre /hr at 5.5 knots (bearing in mind the boats is 4.6 tons) !

Jolly good, nice tidy installation, how long have you had it? Any issues?

I've seen a few 80hp+ turbo engines in <10m fastworker type gillnetter/potting boats over the years, the owners all seemed very happy and they went forever. Although on the 10m+boats the Ford Sabre 220hp (a Perkins engine I think?) seemed to be kiddie!

A contact asked me recently whether Westerbeke engines were Isuzu based. I didn't know, anyone have any information?

I have a 4cyl 65Hp Isuzu coupled to PRM 260 g/box supplied By HMI 5 years ago, it has done approx 500 hours ( VDO Rev Counter display has gone ) it was bought to replace a 4 cyl perkins and is quieter and a lot more fuel efficient. only parts needed have been filters which are now bought from local motor factors as base engine is used in isuzu trooper jeeps.camshaft on this model is gear driven so no belts to change.

Engine was installed in 2000 and has currently done 1150 hrs,(bearing in mind I mainly sail), at 5 to 6 knots at say 1800rpm it always uses 1 litre an /hr consumption.
In my installation due to restricted access the water pump is not the easiest to get at nor is the dip stick, other than that it runs and starts every time.
Its currently connected to it's second 2:1 ZF 10 gearbox and I may look at fitting a PRM box next time, however that would entail having to lift the engine 10mm for input/output shaft alignment.
I do change the raw water pump impellor every year but mainly just for my piece of mind, I change the gearbox oil every 100hrs and the engine oil every year in December!

so would you be using about 13hp @ 1800 RPM
Caer Urfa

I would say slightly more, I normally cruise at 1800 rpm and if a bit lumpy or strong tide go up to 2000 rpm, maximum I use is 2200 rpm as I find the boat will not go much any faster anyhow, maximum speed is about 6.5 knots, but the best thing is I know I have plenty in reserve and the engine is not working it's heart out on long coastal trips, prop is 15" dia x 3 blade.
The Colvic Watson 23'-6" is designed for engines from 22hp up to 35 hp and I think 27.5 hp is a good economical but still powerful enough engine based on the waterline hull design speed criteria.
My mates boat which is the same size as mine has a 30hp Perkins engine in, but runs at a slightly higher rpm to achive the same speed as mine, but this could be down to the slightly smaller Hurth HBW 50 gearbox but with same prop.
