Re: Stus-List Yanmar 3HM35F low compression
Happy Easter to All, Bill is correctFinesse does smoke more that it should upon all starts...but happy to report that after 5 minutes or so of running the smoke is hardly noticable. Not sure what the PO did, but a local diesel shop suggested a fuel additive which I always useso maybe that helps as well.

Re: Stus-List Yanmar 3HM35F low compression
Interesting point about the wife and kids. My girlfriend is a trooper, we didn't have running water or a toilet on board for the first season and a half so I guess I'm lucky. The first thing I attended to before I ever even launched or sailed the boat was the thru-hulls however.

Re: Stus-List Yanmar 3HM35F low compression
Thanks Bill, Your expierience is what I was hoping for, if only I could get it started. As for the injection pump, it was suspect and subsequently rebuilt as a condition of me purchasing the boat. Besides, I have to keep asking, What could have changed between last season and now? Another diagnosis was a head gasket or cracked head but I have yet to determine if the lack of water in the oil rules that out.

Re: Stus-List Yanmar 3HM35F low compression
Bill, Mine was smoking a bit last season too but I attributed it to an incorrectly adjusted Max-prop. My hypothesis may have mislead me to not recognize a low power condition. Anybody ever use any of the snake oil products that are supposed to free stuck rings? Rislone Compression Restore and Ring Seal is just one of many I came across.

Marvel Mystery Oil has been unsticking rings since the 1920s, but I am not sure how to use it with a diesel. For a gas engine you remove the sparkplugs and pour some in.

Re: Stus-List Yanmar 3HM35F low compression
Tom, I have absolutely no idea how many hours. To the best of my knowledge it is the original and the previous owner did not leave her unused for any significant duration. So engine hours is 25yrs. ;-) I did find a scrap of exhaust gasket in the bildge and had heard from others at the marina that the PO had blown the head gasket. He seemed like the type (most sailors) who would try to do the head gasket himself. Josh On Apr 11, 2014 10:56 AM, Tom Buscaglia t...@sv-alera.com wrote: Josh How many hours on the engine?

Re: Stus-List Yanmar 3HM35F low compression
Josh, If the remedies already posted do not clear up the hard start and stalling look closely at the head gasket then the head itself (look for indications of a crack). I had a 1980 CC 36 with a 3 cylinder Yanmar that become hard to start, spewed whitish smoke for a bit and ran rough occasionally stalling. The cylinder head had developed a crack between two cylinders. I ran the engine on with the cracked head for a summer cruise sometimes using the compression release to get the engine to fire. We re-powered the 36 that winter. Other telltale signs of a failed head gasket or crack: oil/carbon in coolant, excess fuel being blown out exhaust, especially at start, whitish exhaust smoke (unburned fuel), a pressurized crank case, especially with lube oil level increasing.

Re: Stus-List Yanmar 3HM35F low compression
I'd think twice about removing injectors to pour any sort of liquid into the combustion chambers.Diesels ignite by high compression. They achieve this by having very little clearance between piston and cylinder head. Oil is virtually incompressible so you run a real risk of a hydraulic lock or worse a bent connecting rod.Put the snake oil in the sump! sam :-)CC 26 LiquoriceGhost Lake Alberta From: Josh MuckleySent: Friday, April 11, 2014 12:38 PMTo: CC ListReply To: cnc-list@cnc-list.comSubject: Re: Stus-List Yanmar 3HM35F low compressionYep that's my plan.

During the first start of the season the engine started rough and powered the boat just long enough to get to the travel lift and then stalled when I throttled down. I did not attempt to restart because I was in the lift well. Upon relaunch, 5 days later, the engine just won't catch. It kinda acts like it wants to, which
Re: Stus-List Yanmar 3HM35F low compression
It works better from above. I would NOT try and run it though. As you correctly mentioned, there is no room for a lot of liquids in there. You need to crank the engine with the injectors OUT and blow the stuff back out before you try and run the engine.

Diesels ignite by high compression. They achieve this by having very little clearance between piston and cylinder head. Oil is virtually incompressible so you run a real risk of a hydraulic lock or worse a bent connecting rod.
