looking to buy a Ranger Tug R25
At the end of last season I began to notice a decrease in top end speed and a decrease in RPMs. Had the marina mechanic look at it before taking it out this season. He said that the turbo was shot and it would cost about 5K to replace it. He recommended not replacing it and just live with the slower speed and lower RPM. Wondering if anyone has had the same issue and if 5K seems like a reasonable charge.

Find a new Technician !!!! 5 K for the removal and replacement of a new Turbo is not out of line. I don't know what engine you have but you do and an easy search on line for parts for your engine based on model, year and serial number would give you the exact price of a new turbo. Then removal and installation labor would need to be added. Believe me it can be labor intensive in these boats the way the engine is installed. The D3 is probably the worst. The Yanmar properly the easiest.

I would have another technician see why the Turbo is deemed "SHOT" It may just need to be cleaned or rebuilt. (1) I would not run the engine with a compromised Turbo for extended period of time. To get me back to port yes, to live with it NO!
 
Depends which engine you have, but on my Yanmar 4jhe-dte the turbo ranges between $2000 and $2500 new. You can find a rebuilt Turbo for about $1500 to $1800. You can have it rebuilt for a little over $1000. I've had my Turbo rebuilt, and also bought a spare off of eBay.

Turbos are are easy to replace on the 4jh3-dte. If I remember correctly around 11 or 12 bolts to remove and replace. $5000 sounds a little excessive to me if you have a similar Yanmar.

Top end speed will also drop out if you fuel filter issues. Did you check that?
 
I have a cummings (actually a mercury) did check the fuel filter (changed it actually). I will get a 2nd opinion before I do anything.
Thanks for the info

I just finished repairing a leak on the water injection elbow on a Cummins. Due to corroded bolts etc I was afraid I'd have to replace the turbo so had everything sourced to do so. It's a couple grand in parts and a full day of labor. It's really about half a day of work but realistically a mechanic is going to make a day of it. So I'd say 5k is high. Replacing the turbo is actually pretty straightforward on this engine. Yes I'd find another mechanic.
 
I also had to replace the water injection elbow. Seems like that may be common problem with this engine. Will check out a second opinion. My problem with that is I need to clear this with the marina my boat is located. They do not allow outside mechanics on their property.

It still runs ! Take the advise of the marinas technician Run it. Run it to another facility that will give you an honest diagnosis explaining his findings. " SHOT " is not a good explanation! The issue is finding a service center to work on the Mercuiser Cummins. Not because they are bad engines, but because most technicians don't want to get involved in the parts chase. Do your home work find all the parts availability and the find a good technician to install them if you are not a DIY boat owner.

I was involved with the replacement of the turbo on my D3 220 Volvo. It was labor intensive. The Turbo is on the starboard side of the engine. The After cooler, oil cooler lines, engine ventilation oil lines, Turbo oil return lines all have to be removed to remove the Turbo. The cost of the new Garrett Turbo was $2600.00 and change, While I had the after cooler out I took it apart and cleaned it and installed new o-rings. The parts Turbo, Gaskets, seals, hoses, from Volvo were just over $3000.00. There was 13 hours billed to the job 120.00 hourly rate.( Warranty) I did 75% of the work because the Volvo Technician was a big guy and was struggling to work in the tight quarters of the compartment. Also because I have a hard time having anyone work on my engine or boat!! While the 5K may sound unreasonable you may find that to be an average estimate if you have a marina or service center do the work.

In my case it was an installation problem. The exhaust hose was too long and was putting strain on the fitting. Combined with vibration it caused a stress crack to start on the weld where the can joins the elbow. I had it weld repaired for $80 and replaced all of the exhaust hose with soft wall to reduce the stiffness a little bit. Properly fitted and supported it took three inches less hose than the previous installation.

You don't need a Mercruiser mechanic to replace the turbo. It's a very straightforward job on this engine. Easily accessed on top rear of the engine. No double jointed contortions required. Also no electronics involved so don't need someone with the Merc software. Any competent diesel mechanic can do the job. The parts are all in stock at Crowley Marine via their website. As I said I just went through the sourcing assuming I was going to do this. They had everything on the shelves. Here's a link to the appropriate page on the web site.

Did you check to see that the veins are turning freely? Sometimes a buildup forms that restricts the veins. Removing the air filter and see if you can turn them with your finger. If you can free it up and running the engine and increasing RPM while squirting in soapy water with a spray bottle can do a world of good.
 
My main concern was finding the parts because as some of you mentioned on this model engine the turb0 is very easy to get to. Thanks for the info about crowley marine. Will try there.

I did order the turbo from Crowley Marine (thanks for that info) came in less than a week. Now figuring out what extra parts I may need (gaskets and such) and order those before I pull the old turbo so I won't be waiting on parts. Crowley is great.
Thanks again for every ones advice

It will be interesting to see what you find. I would keep that Turbo boxed up until you inspect the Turbo. A fouled Turbo with a little cleaning can function as good as new. There have been many threads on Tugnuts where an engine was down on power and the turbo required vane and waste gate cleaning and then functioned as new again. If you find that after removal and inspection the bearings and housing are "SHOT" than you install the new one. if not save your money and send it back!
 
One last question on this topic, I hope. Was able to find all of the parts I need from Crowley Marine with the exception of the heat blanket, mine is a mess. Crowley no longer stocks this item. Looked on Amazon and don't see anything that would appear to work. Has anyone had to replace this item?
Thanks

It's amazing how ratty that thing gets just sitting there. I haven't replaced mine but it's in pretty bad shape. Not sure what I'd use as a replacement. Only really needs to protect on top so the fiberglass hatch doesn't get too hot. And I guess the engine cover if you still have it installed. With a bit of cutting/folding a fiberglass welding blanket would do the trick. You can get them on Amazon for $20 or so.
 
the welding blanket sounds like a great option.
Thanks
