Clark... I agree with everything you talk about in this video, and I want to further emphasize all your good advice by telling this rather long story from my life experiences. I hope that this will save someone from having problems. I, therefore, am re-posting the following: My Father in Law was in the production side of the movie business with Warner Bros. Columbia all his life. I should say here that he was a very serious man, (ex-Navy) who rose to be Director of Operations at Warner Bros. Columbia before he retired. So I have no reason to doubt this story. This is what he told me: Years ago, on location, in the middle of winter in one of the Northern States, a movie scene required a Longboat full of Fur Trappers to be shown rowing upstream. The current on the partially ice-covered river proved to be too strong for the actors rowing the boat. An outboard motor would show a wake, so that was not an option. So, the crew came up with the idea of using an old Caterpillar Dozer from a nearby ranch. It had a winch upfront that they figured could help them pull the boat upstream. They build a little fire under the oil pan, so they could crank the old thing over and get it started. The problem was that the way the director wanted to shoot the scene, there was no way to hide the Cat or the winch cable, so they decided that the only solution was to submerge the cat with an operator in the river. Among some other things, they extended both the air intake and the exhaust up, took the fan belt off, got it started, then took the remaining electrical gear off and drove it underwater where the operator in scuba gear worked the winch. Some greenery on top of the cat hid anything that showed above water, and that did the trick. The moral of this story is, that if a Diesel engine gets AIR, CLEAN FUEL and you manage to TURN IT OVER, it will have to start. (Of course, new clean fuel is of no value if old dirty fuel has previously clogged the injectors). Also, if you want to keep it running, keep it cool with clean oil in the pan. Running seawater through a cooling system is also asking for trouble. Even with a heat exchanger, where seawater is pumped to the engine mounted exchanger. It is one of the most problematic systems on any boat. I see it over and over as one of the main causes of engine failure. This is why most commercial boats (and all the boats I build) were keel cooled … meaning that the coolant is actually piped from the engine through the keel or a pipe on the outside of the hull to cool the Coolant before returning it to the engine. No seawater ever touches the engine! I would try to do my best to convert any sailboat to keel cooling, just to keep seawater away from the inside. I also would eliminate all through-hull fittings by going to a single valve Sea Chest. Look at the Rolls Royce of cruising boats... the Nordhavn line. Yes, they are mostly Trawlers but there is a way of getting that done on a sailboat. Commercial boat engines when rigorously maintained can last for up to 40 000 hours. I build four steel commercial fishing vessels in the early 80”s. The last one, (my profile picture) weighed out at 140 tons. All of them, as far as I know, are still floating and plowing the waters of the Bering Sea. Two of them were accidentally run on the rocks, pulled off, repaired and put back into service. I always installed several Heavy Duty (Racor) Fuel Filters on a manifold system (like you). They could quickly be switched over when one of the filters failed. Also keep in mind that the most likely and worst time for dirty fuel to reach the engine is in bad weather when the boat gets tossed around, and old sediment gets stirred up. Not a good thing under the best of circumstances. It is also important that one frequently inspects the filter(s), and that one can visually see the sediment or any possible water in the glass bowl under the filter. There should be a drain cock. A crappy filter, with a metal bowl, which is many times standard factory issue, will filter your fuel, but will not let you see what you got until you open it up after the engine fails. To further prove my point. In the early ’70s, before GPS, I was single-handing my sailboat just south of Punta Abreojos in Baja on a stormy night when I ran aground on a sandbar. As the boat was pounding in the surf, the portholes blew and submerging the cabin and of course the Engine. Long story...At low tide the next day I managed to get the engine started again. I did that by hand cranking it with the De-compression lever pulled. The minute I let that lever snap, that little Volvo got everything it needed, i.e. clean fuel and air and away it went. I cannot overemphasize the importance of clean fuel. Sadly, the shaft was bent and I lost the boat. I never had a problem with anything Diesel I have ever owned, because I always went overboard on fuel filtration. The only Diesel that ever let me down was a piece of crap Volkswagen Rabbit Pickup Truck. The timing belt broke, and the engine exploded. I take comfort in knowing that it was running on clean fuel until it took its last breath. Long live Rudolf Diesel! I truly love your channel. You are both great resourceful trailblazers and a credit to the sailing community! Good Luck to you both.

My only problem with keel coolers is there is no good way to cool the exhaust. That and when the cooler (which is in salt water) fails it's much harder to fix. Good points on every thing. Was planning on talking about rough seas and clogging filter but forgot during filming. That is best reason to use the booster pump. Not fun changing filter in bad seas.

Good video! I should mention that it made me nervous watching that uncapped used oil jug! From experience the first thing I do is snugly cap any oil bottle (fresh or used) unless actually using it. Also, I don't recall you suggesting a new fuel pump and gasket in your spare parts list- they're inexpensive, small, and oh-so vital. Finally, always use fresh oil (not used) to lubricate the new oil filter. And I personally preload my new oil filters with fresh oil to thoroughly wet the filter media with oil- doing so will reduce the amount of time your engine runs before it sees oil pressure (always a good thing!). I think Amsoil makes a filter system for diesels which not only removes contaminants, but water- this would be a good way to go for your bypass filter system. Happy sailing!

I love diesel engines, they have always served me well. 3 basics diesels need, are Clean Oil, Clean Fuel, and Clean Air. tbh, for the first 1,000 hours of running, I'd change the Oil Fiter, as even though tolerances are tight, you can still get metal bits from wear in, that get caught by those Oil filters, and I don't like taking Chances, it's worse for Gearboxes and Saildrive legs, because No Filters. Change or Clean, depending on type, Fuel Filters, and use biocide additives in the diesel tanks, and occasionally add injector cleaner additive to the most direct diesel tank feed when you are going to have a long run on engine power. Diesels do love Working but it doesn't have to be too hard to get the benefits with good fuel economy. Carry a spare Air cleaner, or get a decent Cleanable one, as you can find yourself sailing I'm very dusty Air, such asvwest of the Sahara. Do a full drain of Gearboxes and Saildrive legs to get those bits out before refilling with fresh oil. Once run in is complete of Gearboxes and Saildrive Legs, add gearbox oil additives to greatly extend life, but Never before they have fully run in, as they are so good, they may never run in properly. That pretty much covers what I've learned over the years, otherbthan how to treat a Turbocharger Properly, which also needs good Clean suitable Oil. On Startup, never Rev the engine, let it tick over for say 30 seconds, to make sure those Turbo Bearings are getting a good Oil feed. On stopping - which opposes Yanmar non Turbo engine advice, do Not Switch off with high engine rpm, as that Turbo is spinning really fast, andbif you switch off, bye bye Oil feed, and hello Dry Bearings, so tick over for another 30 seconds first. Doingnthatbon Land, with good servicing, that Turbo should do a million miles. I've never had a Turbo Failure thanks to following that regime. Clean air is also Critical for Turbo Service Life. Best Wishes. Bob. 👍🙂

thank you, I just subscribed to your channel. when I repowered the Beta Marine (kabouta block) was much cheaper than the Yanmar. I have had my engine for about ten years now and we recently were having overheating problems, we shut the engine off and were sailing when we turned the engine back on we were going against tide and wind, I turned the engine up a little and it started overheating, we were in the channel and I just had to keep going, I eventually slowed down but the it was being very sluggish and when I turned the engine below 5000 rpms it choked out. Uhh what we discovered after we got towed in was a mess, a rubber hose blew off the heat exchanger and filled out 4' deep bilge with seawater. I called Beta and they said I should clean my heat exchanger every few years! who knew I took the entire cooling system apart and put the heat exchanger in vinegar most of the high pressure side were blocked. its and odd thing that is drawn together at both ends and kind of just stays in place, I also am going to change the fuel filers as it choked out and still won't start. thank you for your clear demonstrations

Helps heaps to make a proper check of the oil level, especially if the light conditions are on the darker side. The original marking area are most often really not thoughtful for the purpose…

@Clarks-Adventure4 жыл бұрын
The 4.108 is a great engine but it is probably about the hardest engine out there to bleed. I advise you to NEVER run out of fuel. But if it happens your engine is easier to bleed if you run that transfer pump putting positive pressure on the engine. Then go through all the bleed points loosening each vent until clear (bubble free) diesel flows. It's in the book. Just using the electric pump saves you from having to reach down and keep actioning the mechanical on engine pump.

Those starters are very similar to the starters I've had on a long list of Lycoming (I)O-320/360 aircraft engines. As you alluded, the biggest issue by far is simply the Bendix getting gummed up with old oil, bird feathers (lol) and other detritus. I've had good luck simply spraying the bendix with carb cleaner and then a little dry lube to get it to work properly. On my old Grumman aircraft I always drilled a little hole in the cowl to be able to put the aerosol can straw through.

Get a oil filter relocation kit; something like you find in a Harley parts catalog, or perhaps a John Deere parts store. Getting that up and out of the way makes it easy as pie; and you can even go with a cartridge oil filter so you don't have the messy leaks when changing the filter. And be sure to check the rating of the filter; contrary to what you might think, you do not want a really small (1 micron) filter as it may clog easily which would starve the engine of oil and cause catastrophic failure. And put some oil in that filter when you change it so you aren't running the motor without oil for 20 seconds.

I do really like the relocation idea. Had one on a previous engine and ran it with a reusable/cleanable filter. Really liked that because I could tell if I had issues by looking for metal.

Small hiccup: be aware that although the kit is indeed bolt on as described on their website you'll need different fasteners and a couple of reducer bushings if you have a Yanmar 2GM20F motor - they dont come with the upgrade kit. I received my separately purchased fastener kit at a very reasonable price but it has a couple of wrong size parts. I've contacted John at Electromaax and I have faith we'll work through it. If you're purchasing this upgrade I highly recommend purchasing the fastener kit for your specific motor. The hiccup I'm sure was just an oversight.

15W40 oil is 15 weight oil, it has a viscosity modifier added (think something like STP) that reduces the thinning effect of the heat on the oil. Many boats have two racors manifolded together so when one plugs up you can instantly switch the the other. Diesel fuel, unlike gasoline, will support some forms of biological growth that can be a problem in boats where the fuel might sit in the tanks for long periods especially in tropical climates, also condensation in the tanks. There are additives that can deal with these problems, truckers and farmers generally don't have these problems since they use their fuel quickly. I like your fuel polishing system, I don't know your manifolding arrangement but it would be nice if you could pump from one tank into another, this way you could isolate new fuel until you get a chance to check it out. Spare starter is a good idea. The new 140 amp alternator looks small, problem is that many alternators are overrated and yes they can pump out the 140A, for about five minutes, then they start to overheat. Commercial alternators are generally large with big cooling fans. A good voltage regulation system is also needed.

A big thumbs up, because it convinced me to buy another electrical fuel pump and replace the mechanical one on my engine. Since then it runs far better, starts perfect etc. And has rhe advantage you mentioned of running more fuel through the pre filter, thus cleaning the fuel. I’ve got one question if I may: by adding a pulley on your existing crankshaft pulley, you changed the weight on the complete part. Did you notice any change in vibration on you engine. I’m asking this because mine has the habit of vibrating at 1100 to 1300 rpm more than in the rest of the range. It is a 3 cylinder 27 horse so different than yours. And, if there is a noticeable change, I maybe could do a similar thing.

I just didn't like the noises it made. I think redline for the proform version were like 4000rpm or more. Only difference in the three models was the setting of the governor. Also, need parts?

We installed that on my dad’s boat. V belts belong in the museum not on a boat or car. Mercedes uses serpentine belts since the early 1990es.
@finnerutavdet2 жыл бұрын
Yeah, most of us would change the filter every time,.... but I guess his engine is running so clean the oil is still kind of clean when he changes it, and that that's why he don't see the need for changing the filter as well every time. ....... In some of my diesel cars I actually change the filter in between the oil change (exactly opposite of Clark). ........ The quicker the oil gets black, the sooner or the more frequent I would change the filter, and also for filters paying a bit more is likely better than the cheap ones made in china. ..... And by the way, read the filter instruction for torque when putting the new one back one. Once I did not, and ended up with all of the engine oil in the sump ;-) (it unscrewed itself). ...... Happily I had an oil pressure alarm that was actually sounding (not silent from rust in the buzzer).

With my 20 year old Volvo/Perkins MD22P I can never get all the oil out, but I don't think that matters too much. The other thing I notice is that the oil level always drops quite a lot when I turn the engine over the first time so I have to top it up again. I literally run the engine for a couple of seconds and then check it again and top up. My engine has always flawlessly started and runs perfectly in the 2 years and 600 hours I've used it. I'd be curious to know how many hours you think you can get out of your Yanmar. You might also want to talk about the pros and cons of turbo - mine is naturally aspirated which I believe is preferable on a cruising boat.
@Clarks-Adventure3 жыл бұрын
I bet your oil is filling up your new oil filter. I don't care for turbos but if I had to deal with either a size or weight issue I'd have a turbo diesel. I prefer the idea of turbocharging a diesel over turbocharging a gasoline engine.

I cant say exactly the fuel use for my 2YM 15 2 pot 13 hp on 30 foot narrow beam 3 ton 1969 sail boat It seems to be about 1.5 liters per hour 60‰ gas (estimated 2000 rpm says 1800 but suspect under read from 80 amp alternator larger pully wheel ) going at 3.75 knots. Prop is fixxed three blade 12x9 probably too small Gear box ratio unkmown The previous engine was 9 hp one pot type which many boats 24 to 29 ft use many and say at 4 knots use 1 liter per hout Those size types can expect 12 to 18mpg st 5 to 6 knots That info looks to be about 11 mpg Imperial on 4.56 liters to imp gallon or maybe approx 9 mpg on USA gallon. Yanmar web site show fuel power curves for thiet engine on a per hour basis. It suugests i use 2 litets per hour for my use type That is possibly baded on bigget prop than mine which might allow 5 knots for 2000 RPM. My cousins 6 ton 37 foot 1985 prout Cat with Z Drive large 3 blade 3 pot 37 hp Yanmar seemed to be at 60% gas about 4 mpg imperial gallons in calm at 4 knots . Any head wind it went to 2.5 knots and 3 mpg quicly Boat types dictate fuel use speed ratio. Older narrow boats often in calms return best MPG with correct two blade fixxed props good gear box direct prop drives at higher speeds than heavy wide fishing type motor boats or bigl high windage multi hulls .

Thanks very much for making this video. Got me thinking on different fuel polisher designs. Will the Carter P4594 In-Line Electric Fuel Pump's 6-8 psi be sufficient to push through a Racor 500? Is it a flow through pump, won't it provide any resistance when not turned on?
@Clarks-Adventure3 жыл бұрын
You're welcome. It pushes fuel through the Racor with no problem. It's a rotary vein pump and should flow fuel when off (with some restriction of course). But, I didn't trust it when setting it up long ago and installed a bypass with check valve so I've not really tested that. One issue with this pump is it has a little stainless filter inside. Open it up immediately and remove it. Your fuel will likely be too dirty for it and it will plug up really fast bringing down your whole system. Let the Racors be your filters. If you think friends might like our stuff please share links on social media. Really helps us.
