May be worth also considering what speed your alternator will run at, as the intended drive pulley will give a really high pulley ratio. From memory the A127 type alternators are ok up to about 15000 r/min max, but above 6000 r/min give very little more output.

Lol, thanks for the reminder, need to book in for an eye test myself ! Nope....Light blue engines have never seen India......and have NO Indian parts fitted. Mmmmm, know what u mean !

Be careful using your hand over air cleaner intake, better to use a rag.....and there's a hole in the underside of the intake snout, so rag would block this off when sucked in. Stop lever is on front right hand (belt end, fuel pump side) corner, just inboard of the speed control lever that the cable is attached to. Pull this over and the engine will stop. Oil overfill can be a problem as modern engines run with very little clearance between big end caps and oil level for compactnes. On the isuzu clearance is about 5mm.....and if overfilled oil will splash up the bores. This can cause a dramatic increase in running temperature, excessive smoking and slobber....wet gooey oil dripping from exhaust joints.

In answer to your original question, the 24V x 110A Alternator fitted to Isuzu Marine engines was a Leece Neville 8HLA unit. I'm sure if you get in touch with the Ex HMI guys they will be able to sort out a conversion kit if you really want to go 24V !

Cobblers !!! Engines marinised by HMI were brought in from Isuzu Japan with a clear laquer applied over the engines of which cast iron and steel parts were black with aluminium parts "natural". NOT matt Black.......HMI painted with a sealer primer then top coated in "Boots" blue. The lighter blue engines are japanese built Isuzu engines NOT Indian.....there are no indian built copies of the Isuzu L Series ....... YET ! No one who was made redundant from HMI when in Gloucestershire is selling Isuzu engines now, be they Boots Blue or Lighter (Sky ?) Blue !!

Why is this a "major" problem ? Surely an inspection by a QUALIFIED engineer needs to assess the "problem". On the Isuzu marine engines built by HMI, if you turn the key off the engine keeps running, because the STOP button no longer has power. The stop solenoid is energised to run, so needs power to STOP. Procedure for stopping is to press the clearly marked STOP button, and onece the engine has stopped, turn off the key. This is all in the handbook. The only exception is if you have an ex Black Prince boat, which you do not have. These had a module fitted behind the panel which allows stopping via the keyswitch. This module is retrofittable, but from past experience, HMI will not know what you need !! Maybe best to try Engines Plus, run by the blokes who ran HMI. As far as the oiling is concerned, has the engine been filled with the correct spec of oil....API CC ? If you've refilled at the first service with higher spec oil and done no hard running to bed the engine down, this may be the problem. I would suggest you give the engine a good thrashing....preferably on a river to avoid wash and bank erosion. It may smoke like hell to begin with but may well clear. This will burn oil out of the exhaust, but bedding the engine in is probably the problem. Hope this is of help !!

The biggest problem with marinising most automotive diesels for the Inland Waterways is thet they are now turbocharged. The Isuzu marine units were industrial engines, cast iron head and block, and whilst there are some hints of the automotive engines (valve gear ?) they're completely different to the Isuzu automotive lumps. The canals will kill a turbocharged engine as the cylinder temps will stay low due to the low load factors causing oiling up etc. The Subaru boxer engine is a nice idea but would need to be naturally aspirated. Even if the turbo was removed and the injection system recalibrated the RCD demands emission compliance, so testing and approval would be a nightmare.....and expensive. lol, so do I !!

Buy now whilst stocks last at HM Plant. I believe they will no longer be distributors for Isuzu Industrial engines on which the Isuzu marine product is based after tonight. Isuzu will no doubt be announcing their new distributor sometime soon. It will be interesting to see which engine suppliers are at Crick show. Oh, and the light blue Isuzu engines are built in the UK on Japanese Isuzu's, nothing to do with India !!

The original Isuzu marine engine designations were their gross rating in bhp at 2600 r/min, considered to be a "sensible" max speed for IW. However due to their engines appearing less powerful than the competition, the designations were revised to reflect the max output at 3000 r/min, which is the max rated speed for the Isuzu l series engines.....hence Isuzu 33/35, 38/42 & 48/55. Hope this helps.

That seems pretty good service if they got someone there quickly. So what did it cost you then ?
