He mentiones that a bit of oil will run down into the bilge and mentions that it is no big deal. Well, one drop of oil can contaminate about a quarter million gallons of water. Not that you want to drink the water in your harbor anyways but well, the reason why this is the case is because we collectively think "it is not a big deal". This is just a wordy way to state: Please be very careful that NO amount of oil / diesel / lubricant gets into the water. We all will benefit downstream. In a few years (10 or so) all new boats will use electric motors which will make this mess all go away but until then, let's all be careful.
You sir have grossly mis-quoted me, @5:55 I said change the filter after the oil has been drained (suctioned out) and place a rag underneath the filter in advance to prevent oil dripping down into the bilge when replacing the filter. Also, the boat and I hope most boats have an oil sock in the bilge. Good day to you.
Slight engine overheat combined with steam/white smoke on Volvo Penta 285 hp: impeller OK, cleaned the heat exchanger, checked exhaust elbow, checked raw water flow and all seemingly OK. The six injectors were all removed and sent away for testing and they were all clogged and varnished up. The tips were replaced and they were thoroughly cleaned and soaked. The service shop said that there was a poor spray pattern and most likely unburnt fuel causing heat build up etc in exhaust and thus steam and smoke. Re-test due soon but hopefully that will be the end of the problem!
Yes, the mixing elbow is considered a wear part that needs to be replaced. The stock cast iron ones will last for years, but supposidly the stainless ones will last forever becuse they don't corrode like the steel does in salt water.
I have two Barient 22STs--they seem to be single speed. Was there a single speed 22ST? Also, I have removed the top piece (as you did in your video) but can't lift the drum. I've put lots of PB Blaster around the top and let it soak in--still stuck. Suggestions? Thanks for sharing your knowledge.
@@Ingeanous winch spins in one direction only. No other retaining ring-- it's identical to yours. I'll continue to squirt PB Blaster around the shaft on top. Thanks
Hello Francis and thank you for your perspective. As DIY'rs we go into these projects not knowing what we will find and make judgment calls. Little things like O rings for an old engine may be hard to source so we roll with it.
@@Ingeanous As a sailor with an engine, one would always carry all common replacement parts for water pump servicing on board. A failed pump would kill your engine for sure.
How many hours was this engine? Mine is about 2000, used in slightly salted sea (Baltic) and there is no troubleshooting with overheating. Is it time to inspection or not?
Unfortunately, our engine is older (1990s) and is not equipped with an hour meter. With that said, the cooling system will start to clog over time with salt and other organic buildups adhering to hot surfaces, so this is a good exercise in maintenance to keep the engine healthy regardless of the type of water <she> lives in.
I just realized how exacy similar your yanmar diesel is to my ym 1500d tractor. That's awesome and if it's as reliable and bulletproof as the tractor engine has been with an extremely high amount of well maintained hours that I have on her, you will have no issues with it as long as the maintenance is done and she keeps cool it will rum forever. 🖒
I grease the hose with anti-seize so it's easy to separate from the exhaust. Greased the gasket with anti-seize as well, never have to change gasket for years as it won't stick to metal nor gets damaged.
we have found a more reliable way with the descaler - a 20 litre bucket and a small 12v pump - essentially get your solution I think its 50/50 and hook into the raw water supply pumping thorugh the completes cooling system with the recovery line that feeds the exhaust elbow being the end of the circuit - circulate in one direction for 20 mins - the swap the flow so you push in from the exhaust side and recover back to your 20 litre bucket from the raw water supply. Seriously effective. - I would really like to know what the tool was you used to take out the stripped nut
Very helpful. Excellent delivery. My boat and ya at is 46 years old and was potently neglected. So, it helped to freak me out too even tho I am a killed diesel mechanic the marine portion is new to my. Seems I have some work ahead.
We repowered our old boat with a Beta 16, which was a Kubota based engine. Similar to the Yanmar, but different. We never had any problems with the Beta! Of course we did the regular maintenance and she reciprocated by always good to us.
To keep hoses from collapsing, buy a stainless steel spring , the same diameter as the inside of your hose. Made for that purpose. Available from automotive parts stores. Cheap insurance to prevent overheating. Blown head gaskets,all that good stuff
