Hybrid is silly money. I'd be a bit worried about the number of people who can fix problems. A lot of power electronics in there. Ok for a DIY but if spending £20k on an install you don't really want to be getting screwed over on reliability terms..
I'd probably go Beta Marine but there are a few choices and the Barrus Shire yanmars look quite good too.
Big fan of electric boats in fact I am in one right now (a canoe) but scaled up to canal boat size it gets too complex and expensive. For now.
I think the ideal thing would be a replacement rudder with a built-in pod drive. That way you can keep the existing install undisturbed and have a choice so if the electric just is not satisfactory use main engine.

11000 hours, that's about the same as my RN. Just spent quite a lot recently getting the heads refurbished, it's made a big difference. When you think about it, 11000 hours is similar to a car engine having done between a third to a half a million miles. Maybe it's worth getting it refurbished now anyway. Mine starts much easier in the cold and sounds much throatier. What sort of engine wouid you go for if you replaced it? Go hybrid? Possibly a vetus or similar. I'm not bothering to go hybrid. 1. I'll probably sell it once it's done and 2. as a liveaboard, electric or hybrid just ain't viable really. I think as widebeams go, we probably do greater distances with this one ourselves, whereas the majority only cruise small areas, or sit in a marina. Somebody buying it won't be keen on an electric or hybrid set up. If you could get onto a river and give it a beasting it will more than likely clear up, industrial engines normally run at 1500 rpm and under a lot of load, in truth most boat engines have the easiest of lives which is not what they were designed for at all. Good luck with a very easy cheap fix

All sorted (touch wood). Gave it a good thrash yesterday, then checked and adjusted the valves this morning cold. Just ran it for 6 miles this morning and it's purring like a putty tat. I did also check the glow plugs, one was 1.2 ohms, the other 3 were 0.7, so I'll need to change those before winter. At some point I'll have the injectors out and reconditioned. Thanks for those that contributed sensibly, especially tony.

I used to use slick 50 oil and fuel additive. I don't know why I stopped, but I'll remember in future. I'm chuffed really, for some silly reason I've got an affection for the isuzu. I've also discovered parts are not actually that hard to find once you start looking seriously. Engine plus seem to be able to source most parts. All good. 👍

That's good. I was a bit surprised to hear parts would be awkward to find for that one. They do seem to be quite nice units well packaged. I've heard good reports about them although never used one myself. 11k hours is quite a lot so if it's still good at this time you must be doing something right If you had been considering repowering in order to sell the boat thats another topic but it seems that unless the engine is nackered it would not be worth the outlay.

They are good solid engines, and I've never really worked it hard, that's probably why it got gummed up. With a hospital silencer, it's very quiet and hardly noticeable tappet noise. Usually half a litre an hour on diesel, a bit more when the washing machine's on. I had a good root around and found no oil or water leaks. No point in changing it out for a sale, it'll probably do a few more years yet.

I have always been advised that wherever it is possible, give the engine a sustained burst in higher than usual revs.
I wondered if cruising at 1400 or 1500 rpm where 'safe' instead of 1100 or 1200 rpm for a short burst is sufficient. Obviously on a river it's much easier to have a 'thrape' at really high revs.
Alternatively I wondered if giving the engine a sustained blast of high revs whilst out of gear will have the same effect ?

Nope. Are you calling me names and mistyped the first letter ? Or are you dismissing all my post in its entirety ? I appreciate that responding to my questions is optional, but having taken the trouble to reply, I'd like to understand what it is you're saying Rog

There's an American (Boston, Mass) radio show called Car Talk, where the 'Tappet Brothers' help callers with their vehicle problems. They said when they started in business in a garage/repair workshop they loved Isuzus because they always had Isuzus in with faults (= that's how they made their bucks!).
