I'm am considering the following add on/modifications to my Yanmar. I'd like to hear thoughts from anyone who has experience with any or all of them or thoughts from those of you knowledgeable in diesels. Sorry for the length of this post but here goes... 1) Pre-Luber. This is an add on oil pump that prelubricates the engine prior to starting. Since most engine wear occurs during the first minute or so after starting while the engine lubricates itself this should dramatically decrease wear and tear on the engine, starter and battery since it will also negate any need to cold crank the engine. 2) TF Purifiner oil filtration system. This is supposed to cut the need for oil changes down to nil. It also allows for oil sample analysis which will spot problems starting to occur in the engine way before they become major repair issues. 3) Turbo 2 Air Filtration. This is an add on to the existing breather system. Since the breather on my Yanmar has no actual filter because of the limited air flow in the engine compartment I am concerned about constantly pulling in all of that unfiltered air. This is a system with a spinning propeller that kicks out impurities without any reduciton to the airflow into the engine. Any thoughts on these mods would be greatly appreciated. These are fairly low cost additions that I'm told can double or even triple the life of the engine.

Lots-a money
Wow Rich, you must have lots of money to toss around and be even lazier than me! 1- Prelube: flip compression release lever(s), hold fuel shut-off, crank engine till oil light /buzzer go off. BAM!- pre-lubed PROPERLY. 2- You will NEVER eliminate the need for oil changes and the Yanmar filter is more than adequate. This sounds like more hype for the yokels. An oil change is so simple and easy I don't see what the big deal is. There are too many good reasons for changing the oil to try to find a way to avoid them. 3- Turbo 2 air filtration??? Pulleeze!! Put a Yanmar or K & N filter element in the stock filter housing. If you really think there's a restriction DRILL A HOLE! The chances of actually having a restriction to air flow are somewhere between slim and you've got to be kidding. Take a close look at your boat some time. You'll see that there are lots of air passages feeding that engine. Besides, if you really want that sort of filtration an oil bath flow reversal system is cheaper and a lot more effective, but come to think of it, an oiled K & N element would do about the same thing.

I'd have to agree...
...that unless you just like extra stuff in your engine compartment that could possible break, jam, crack, loosen, or flat fall apart (eventually) these items are not necessary. Maybe I'm just one of the lucky ones, but the longest I've ever cranked the engine (2GM20F) is about 5 seconds on a really cold day. Now in Texas, that was about 30 degrees, but the engine busted right off. Normal starting takes less than 2 seconds on the switch. In San Diego, I suspect 30 degrees around the engine would require some sort of refridgeration unit? Your motor should start fine and the three to ten seconds required to lubricate the engine is not that damaging. I've run diesels (automotive) without prelubing for over 400,000 miles (6,000 - 8,000 hours) without any major failures. (Finally traded the ol' dog in on a new truck with larger diesel. Tim Allen Mode: uugh...more power.) The Yanmar is even tougher than that by design.

Huh?
Someone else had the definitive post on this thread... A Yanmar diesel will outlive all of us put together, period. Mine has been chugging along for 22 years, everything original parts except for one exhaust mixing elbow.

Power Boat?
Rich: Are we talking about a diesel power plant in a "stink pot" or a diesel auxiliary engine in a sailboat? Key word is auxiliary, I think. Bob Gillan; S/V Far Bugle
