Marvelous presentation of this often misunderstood subject. You cleared-up some of my misconceptions. Thanks.
New subscriber and I want to say you are now one of my favorite channels as I’m a newer captain coming from large center consoles to med size diesel vessels! Keep up the great videos! Thank you!
great info. you won a customer. well presented.
Excellent presentation very informative. Thanks
Great video, thank you.
The saltwater pump on a marine diesel is almost always an impeller pump, whose rubber vanes make a good seal against the metallic pump body. Unless the impeller blades are damaged, it would seem that there should be no path for seawater to pass a stationary impeller pump to flood the exhaust. Yet I have experienced a brand new engine suffer exactly this problem. Can you explain how this can happen?
great video thanks
Could you please talk about winterizing the water muffler. i presume there is a drain that needs to be emptied.
Can I use the wet exhaust hose for radiator hose? Thanks
i never hear of "Glow Plugs" being used in marine deisel engines. I have contacted a few narrowboat owners in England and they don't seem to be knowledgable of these plugs. In Canada they appear on all deisel engines due to our winters. Am I missing something or do these plugs just don't exist in marine engines?
Hi Markrant1...... glow plugs all over the place, particularly automotive, in New Zealand.... which can get seriously below freezing in the southern areas. ON You tube, a lot of the English narrow boat owners have other tricks, like the spray of ether up the air intake, actually lighting a fire in the air intake (a rag with diesel) to increase compression.... we are talking about a little old fashioned, and possibly risky, here.
I am sure modern enough marine diesels would have glow plugs for those very cold situations. OR alternative methods for a very cold start, in their operation manual.
Thank you Peter for your reply@@colonelfustercluck486
Never activate your glow plugs if using ether to start a diesel

Glow plugs are definitely a thing in all non direct injected diesel engines. Engines with direct injection can sometimes forego on glowplugs but in very cold climates they are usefull. My Mitsubishi based Drinkwaard engine (non direct injection) has them and the same engine with direct injection has them as well.
Why is the system designed as such to create all these problems in the first place?
Why not dump cooling seperate to exhaust??? Crazyness.
Exhaust gas is hot and will melt the Exhaust hose. Dry stack Exhaust eliminates this but is mostly used in large vessels.
Vetus/Maxwell making the rest of the marine providers look like amateurs.
The dutch don't muck around
