    Posted: 02 September 2019 at 15:41
Hi
 
Have a Yanmar 3JH4E with SD 50. Clutch cone was changed 3 times over the last 10 years and approx 300 hrs between changes. As we all know - the SD40 and SD50 doesn't live up to the good reputation of 'Yanmar Engines.
 
There is a really good Youtube video how to fix the cone which I did and the saildrive now works perfect again. 
 
However - I have decided to change both Engine and saildrive to the new commonrail 3JH40CR and the new SD 60. I guess there are only benefits (investment cost excluded).
 
Is there anyone that has used the new SD60 for a long time without problems?
How many hours have you Engines been running with the SD60?
If any issues with the SD60 - what kind?
 
I cant find any "problem discussions" on the SD60 on the internet nor in this forum but I believe there are many that are interested in how this new sail drive works compared with the old one.
 
Looking forward to some input/comments.

BTW - I have a brand new clutch cone for SD50 if anyone is interested to buy.

Hi Morgan,

I made  that decision 3 years ago.
Still have the 3jh4e though, never had issues with the engine, total of some 1300 hours now.

So far The SD60 worked without any issues for 3 years and some 600 hours.
Changed the gear oil, 15w40, once.
Yanmar was rather cooperative.
Never regretted the decision.

Hi Peter,
 
I agree with you - the engine itself is good and I had never any problems with it.
 
However - I will get a good price on the package and that is the reason I will change both. Moreover - a new engine after 14 years will give me a good feeling plus there is a posibility to get around 4000 Euro return for the old engine and sail drive. 
 
I have to ask you - why don't you change the gear oil more frequently?
Given the costs to renovate a sail drive I would really change oil each year,,,
 
Anyoneelse that used a SD60 for many hours?
Would be great to understand if there is any issues with this drive?

I really don't know of this, but....

I have heard that new engines comes with turbo. Is that a benefit?
I am concerned with a turbo as I often just start the motor for 15 minutes to warm the water and get some charge.

Anyone any thoughts about this?

Hi
 
Don't think there is a turbo on the new 3JH40CR.
Pls create a new topic on your question and pls let us get comments for SD60 on this thread.
 
Seems like SD60 works fine or?
Anyone with problems/issues on the SD60?

If you have that much money to spend i would put it into a set of quality sails and instead spend US$600 on the SD50 upgrade kit that replaces the brass washers with thrust washers, vents the case and use GL-4 oil and you will have many years trouble free use from the SD50, i have posted a couple of comprehensive posts on this subject if you use the search function.

I have 5 years and counting after upgrade to my SD50 and no issues. 

If you google 'problems SD60 saildrive" you will see they to are not immune to problems.

I just received the SD50 upgrade kit. Will do the repair next week myself. Will report here how it goes. 

I do not understand why you will change to the SD60. Seems expensive compared to fixing the SD50 even if you need to do it every 300h.

Well - a few different reasons:
Engine is now 14 years old and still needs maintanance for approx Euro 2000.
Got a really good price on a new Engine/saildrive - around Euro 12000.
Will get a return of approx 4000 Euro for the old package.
Labour cost for changing the Engine and SD will cost me around Euro 2000.
Upgrade kit - Euro 500 + a few hours own work,,,
 
As I see it - cost for a brand new common rail diesel Engine with the new SD60 will come out at Euro 7500.
I think this is ok considering the value we get in return. (Hopefully many years of trouble free motoring when not under sail).
 
I even believe the second hand value of our boat will increase with a new Engine and SD. If I would have plans to sell the boat - I would not consider changing Engine but we plan to keep the vessel for Another 15 yearsSmileBig smileHeart

Hi Toholthe,

From where did you get the upgrade kit and how much did you pay for it?

Hi,

You can contact Gideon at saildrives@yahoo.com

He is very helpful and willing to answer questions. You get a manual with the kit you need to read many times to complete the upgrade. I am in the middle of it now. The clutch is in pieces in my basement. It takes some time, but itís not very difficult.

I paid USD 581 including shipping to Norway.
