Although my R 25, 2008, is for sale, i always tell everyone it has been the best boat i have ever owned.
I have been happy with the boat and i have not felt the need to make many adjustments or modifications.
I am curious about others who have the 110 Yanmar as their engine: have you been satisfied with the performance, reliability, speed, etc of the engine? Have any of you traveled long distances as live aboards with the 110?
My experience has been positive. I'd be interested in other opinions.

Mine is still going strong - 2007 R-25 - 1000 hours, 6000 miles, no complaints (except I did have to rebuild the turbo - at 800 hours because the engine was smoking.... a result of cruising at 6 kts for two seasons and never sealing the seals on the turbo!)

We cruise at 10-12 kts, 2800-3000 rpm when in a hurry (2.5 nmpg), but prefer 6.5 kts (6 nmpg) when we have time.

We are leaving June 1st to head back up the Inside Passage - 3+ months this time. Can't wait!

Our experience is very similar to Mac's. We had some issues on Day One but they all went away thanks to a very good assessment and the addition of a large dedicated ground cable from the engine to the ground buss. Now, the Laurie Ann has nearly 600 hours on its engine and 3,500 miles under the hull. We also rebuilt the turbo after 90 days of running the inland rivers from nearly Chicago to Mobile Bay at 8 knots I have replaced the sea water impellers (my fault) an the water exhaust system (my fault, again).

Last month I replaced the fuel filters and luckily found a nearly plugged Racor filter. We remain quite happy with the engine running at 11-13 MPH at 3,100 RPM.
 
We loved ours on Solitude. We ran at 6 to 8 knots on each outing with a WOT start and finish. Never had an issue with the motor! When we traded her in, she had 250 hours on her. (Loved the fuel economy.....)
 
Mac,
Curious about "sealing the seals"....are there telltale signs if this is a problem?

I also understand that there is a simple check one can make to see if the turbo is "spinning"...i seem to remember a post on that somewhere.

While i don't now have any problem, i'd like to be proactive about things that lead to big repairs.

I was told that you need to run the engine up to heat the oil & force it into the seals of the turbo, say once/trip for 15-30 minutes at a good load. Otherwise, the oil sneaks past, and the engine smokes. The turbo was still spinning OK - actually, I didn't think it was much of a problem, but both Ranger Tugs, and MER said it was so I believed them!

"sealing the seals" is interesting. Are you talking about sealing the edge of the turbine blades? Or, sealing the seals around the shaft of the turbine? I'd like to see a cut-a-way of that turbine. I think I'll check the Yanmar site and see what they might have.

Thanks Mac..

The simple check of the turbine blades i heard about here was that you can open some part near the turbo, put your finger in (engine off obviously) and feel if the blades turn...does anyone know of this check?

I had the 250 hour check, and service, but i thought this might be something to know.
Can't remember who put it on here and i can't find it.

I have had about five close sales of the boat. Lost them for various reasons, but none had to do with the boat as is, or the engine choice..mostly loans, or space needs, or things like that.

Tom,
I posted the information of checking the turbo, a procedure that I learned from the mechanic who rebuilt my turbo. It is simple, remove the air intake screen, and reach inside the turbo to feel the blades. Push the blades and they should turn. If not, the turbo is seized and needs to be repaired. Your fingers will have some oil on them, so have a rag ready.
 
Thanks for that input, John and laurie.
I think this small thread is useful...good input for those of us who have the Yanmar 110, and clarification of some issues people have had.
In my experience with eight boats, engines always have some problems. The secret is learning what they are, then correcting or adjusting.

For me the Y.110 satisfies my need for (relative) simplicity, repairability, and economy. And i like the sound of it

I had an earlier version of that engine and loved it, for all the reasons you foks have mentioned.

When i sift through these responses, and search the threads for other points, it seems to me that the engine has proved hammerproof...EXCEPT for one thing: turbo problems...when i read the manual, and listen to the various local mechanics, i get mixed messages...If the manual had said , maybe in dark print capitals: FOLLOW THE PROCEDURE NOTED BELOW TO PREVENT DAMAGE TO TURBO> 1. RUN THE ENGINE AT...RPM AND AT LEAST EVERY HOUR OR SO DO THE FOLLOWING...2. WHEN SHUTTING DOWN FOR THE DAY FOLLOW THE PROCEDURE BELOW. ETC.ETC.

At least for me, i never had that kind of definitive instruction...I think i lucked out, but just by luck.

Tom,

My Yanmar in the R21EC doesn't have a turbo, but the operator's manual does give directions similar to those you wrote in black caps. They are part of the advice for keeping the engine running as cleanly as possible.

I've spent many years with turbo charged engines, as far back as the Chevy Corvair Monza. Two important things to remember, keep the oil clean and always let the turbo cool down after hard running before shutting the engine off. My wife's Audi AllRoad has an oil temp gage to help keep track of the heat generated by the twin turbos in her car's engine.
