Yanmar 4lh ste. Yeah, i run it full throttle quite a bit. The exaust upstream of the turbo just has a nice thin satin coat. I think the problem is the rust build up and the elbow. The mixing point is only about 8-10cm from the turbine wheel by design. $1000 every few years feels rather stiff for a poorly designed elbow but that's the boat life I guess

Thanks Neslepaks. Krogsrud replaced the turbo for my dad the last time about 6 years ago, so I'm not sure I'm keen to use them again. Charged new turbo price for a rebuild too. I think it was about 40K nok. I didn't do any mechanical work back then. They have done some other work I founds somewhat shoddy too. I might give Vestfold a call.

I highly doubt the turbo is damaged, so long as you use it regularly, the rust is pretty soft. I'd just clean it out with a wire brush, and maybe think about spraying some oil into there when you winterize. Do the turbine blades have any wear where they're touching the housing? Barring that, maybe have the housing and elbow ceramic-coated on the inside? I've never heard of it, but maybe it'll help. sharkytm fucked around with this message at 20:04 on Oct 24, 2019 |

Hard to say how worn they are since they are completely flush with the housing. Can't see without taking the turbo apart. There are no bent or chipped blades though. The boat did work fine, so you might well be right that its all right. I'm not sure if there is anyone doing ceramic coating in a reasonable distance from me. I have seen some people welding in a stainless sleeve in the exhaust outlet. Might be worth looking into. Thanks for all the feedback guys.

For some engines there's aftermarket exhaust elbows made of stainless steel - I know I've seen them for Volvo Pentas at least. Not sure if it's different for turbo engines though.

Generally the hot side of the turbo is just held on with a V band and can be knocked off and cleaned out. I’d find out how much it would be to get that housing beaded and ceramic coated before replacing the whole turbo if it hasn’t damaged the turbine wheel and it doesn’t have excessive shaft play

If the turbine is good and the seals/bearings are good, there's no reason to replace a turbo.

I’m not sure if it’s a factory recommendation, but we generally recommend customers replace their mixing elbows every five years on Yanmars. They just like to eat them up, they are impossible to inspect, and the alternative of it fails is worse (like your rusty, maybe soon to be dead turbo). That said, just clean the rust up and run the fucker hard. People nursing their diesels like grandma driving to church are responsible for more 2000-hour rebuilds than the guys who run them at WOT all day.

What engine option did you go for? Those Yanmar diesels are actually just marine versions of toyotas diesels- the 8LV series is based off the 4.5L 1VD-FTV in the 70 and 200 series landcruisers and their 6LP engines were based off the 4.2L 1HD-FTV engine

Yep 8LV-370. Should be good for 28 flat out and >20 cruise. Not yet heard anything negative about these engines and they've been out for about a decade now I think? It's also quieter than the VPs.

So me and dad did a small 700 mile roundtrip to buy another old old Solo inboard engine for his collection. Of course it lacked some parts and wouldn't start despite the ad and the seller on the phone describing it as "ready to drop in the boat". Still bought it. My dad was grumpy all the way home about it.

Regular two-stroke, made for starting on gasoline and then switching to kerosene but runs ok on just gasoline (since kerosene isn't as easy to come by anymore).

 dur yeah, i was doing all kinds of mental gymnastics to make it a four stroke which was very stupid!kind of cool. it's pretty easy to get kerosene where I live in the US, but i think it burns quite smoky.

Also lamp oil is kerosene. Could it burn diesel, that’s not too different from kerosene?

I was considering getting a RIB as a starter boat for some river/estuary boating. Did some research, been reading this thread for the past year. Went to look at the cost of a second hand RIB. 5-7m length.  €14000 Cheaper badly maintained ones with no engine that requires considerable work €5000-7000 Not sure what else I expected

It's a huge boat in quite good shape and everything works. I know sailing isn't for everyone, but at least in Scandinavia you can get an amazing amount of sailboat for very little money. I've seen very well maintained IF-boats and other small but seaworthy sailboats go for like 2000€, sometimes with like 3-4000€ invested in them (new engine or new sails) like 5 years ago. Big marine engines are crazy expensive.

One thing I've wondered with inflatable boats like that, is how long does the rubber/whatever polymer last? I know a lot of them have covers over the inflatable part for abrasion and UV protection, but does the rubber eventually degrade? If you have a RIB from the 80's, how likely is it to need new rubber even if it's been cared for well? Or average?

From the Raspberry Pi thread. It's nautical and there is certain degrees of insanity involved so I though of this thread.Hadlock posted:Mildly interesting. This guy lives on his boat and programs his raspberry pi to display charts and weather data, and also drive his boat in a straight line even in ocean waves.
