What gel did you add to the boats and why? thanks!

What is the hose that goes to the heat exchanger called? Or maybe you know the part number. Thanks, I’ve been enjoying your videos.

I recently purchased a boat with the 3GM30F and found this video very helpful. Would you know if there are zincs on the engine? Manual says there are three on 3GM30 and gives location, but I don't see them as described.

Thanks a lot!

Thanks, that was informative and fun to watch. Your engine is MUCH cleaner than mine, my boat is a derelict Morgan 35 and I am getting ready to fire up the engine, if it will fire up. Otherwise, I'm over 70 and have a large reservoir of learning from the old days and am completely confident in my ability to rebuild the engine, myself. Well, machine shops have tools that I will never have and they know to use them.

Thank you for sharing.

Did you get the parts you needed for this project at the Chelsea Drugstore by any chance?

A few notes to add to perhaps another video. The inlet hose usually comes from a raw water strainer which is a daily check before operating the boat, and it catches any plants/algie (even small fish that make it through the thru-hole-valve. Secondly, on both hoses two clamps is the prefered method of installation. Lastly, I recently completely rebuilt from scratch my 3GMF engine on my boat, which is the 22 hp version of the 3GM30F engine (slighly larrger piston displacement, otherwise the same engine internally and externally, and actually replaced the 3GMF in second half of the 80's). I replaced several external components with new ones, and saved the removed companents (starter, alternator, cooling pump, secondary fuel filter, fuel injectors) as spares, including the raw water pump. I keep the spare completely rebuilt including the flat bracket, and when service time comes, I simply replace the entire turn key pump assy, and rebuild and store the removed one to be the new spare. Saves times and if I find myself with a clogged pump, or faulty impeller, I have one handy ready to go in. Another tinng is the rear cover. If anything foreign goes in the pump past the strainer, the inside of the cover gets scored. This does not produce a leak, but because the impetter clearances are increased, the pump becomes inefficient, which is another reason why I even keep an extra cover handy, along with two or three impellers and gaskets. Cheap insurance. Tough to sail several hundred miles, and finding out the engine overheats when trying to motor to a marina, and finding out, no spare parts are readily avilable.

Your ball dropped.

Among the best of dozens videos that try to explain how to bleed a Yanmar 3GM30 diesel engine. This video is well done with excellent audio, visual, and presentation of information.

Crystal clear. Thank you so much! You are a superb instructor!

Nice ending!! Tres classi!!

Did I miss it....the Filter Number?

Did you start on 1 or both?

Tip of the day. Install a small heater inside the motor room. Ill start the heater, get my sails ready and start the engine. My way of starting a 30gm without extra gas throttle..

Fantastic video !, just what I was looking for...same model filter mount I have...every other video I've found so far had a T-screw on top of mount and lift handles on the filter cartridge?...glad you showed the bleed pump with the white plastic knob on top of mount, that's what I have too, but just thought it was a bleed screw, not an actual pump. Great detail captured in video work too, could actually see bleed bubbles and fuel...nobody else captures that, all too far away and/or filmed by somebody not understanding the job and what needs to be seen...if you did all that camera work yourself, that's even more amazing, well done !! 🙂

Sorry but he missed (in fact got wrong!) The most important fact that you haveto get the rotation of the impeller THE RIGHT WAY AROUND!

I see that you sold Sure Shot. What are you planning to get next?

Thank you for the awesome video! Just the info I needed.

Thank you for the great, clearly and thoroughly explained videos!!

Thank you for sharing so much information.

Thanks so much for the great info!

Yea that impeller will be gone in no time. You should at least keep the seacock on

That pump and the alternator are not original from the factory( they should be same colour as the engine), why did you changed them?

How many litters oil

I noticed that the blades on the new impeller were bent in the opposite direction as the one that you removed. Did that turn out to be a problem? Great video. 👍

For cold starting, full throttle setting advances the injection timing, but be prepared to reduce engine speed immediately once engine starts. Having the injectors serviced is a must. Unfortunately, the typical injector wear items are now discontinued parts, so expect difficulty sourcing them. Fortunately, a local Yanmar parts dealer had new injectors in stock at a reasonable price compared to rebuilding

Use the pump on the Racor filter assembly to purge air when bleeding the fuel system. It does the job much better.

ONE OF THE BEST AND MOST COMPREHENSIVE VIDEO IVE SEEN.... MY IMPELLER IS A DIFFERENT DESIGN WITH NO BAR BUT EVERYTHING ELSE IS AS YOU DESCRIBED... GREAT JOB..... I WOULD LIKE TO SEE A VIDEO ON FUEL FILTER CHANGES BY YOU IF YOU HAVE ONE

I love this already. It's about the tenth Yanmar oil change video I've seen but the first where it started with the basic steps and just went through them. Thank you.

Excellent information, clearly and concisely presented with excellent video footage. Thank you very much!

Thanks, great vid and very clear instructions. I have placed an outboard primer pump at the tank exit. Pumping this has greatly decreased the anxiety of removing air from the bleed points. I don't need the small butterfly pump.

great video,thanks!

Thanks for showing you turn the water valve off……..

Great job excellent narration

I'm currently refitting an E29

Very nice boat. Thanks for sharing. The traveler is mounted on top of the cabin.. is that working out okay (as opposed to being located in the cockpit)?

Great job! The manual was not helpful. I can do this now!

Thanks for the vids. Like most others here, I have the same engine so I've downloaded all 3 vids for servicing tomorrow. Cheers.

I believe the Oceanis 31 has a spade rudder, not twin (dual) rudder.

"You can't always get what you want..." thank you for this helpfull video...and good references. Pascal from Switzerland.

I’m running a 29’ it’s awesome

THANK YOU! Without your video I would have never got my engine running again. I couldn’t figure out why the butterfly valve was not working. Repositioned the crankshaft(?) and it magically worked!!

Interesting, I have an 89 2GM20F on my Hunter 335 and yea having cold start issues so might give this a go… doesn’t help that I live in Northern Ireland so it’s never warm lol

Thanks for the video! This helped doing both filters on my 2YM15

An R20P filter is 30 microns. P = Primary (30u), T = Primary or Secondary /Final (10u), S = Secondary / Final (2u). The R20 refers to the housing compatibility, although I don't follow their logic. My R215 Racor takes R15P, T, or S filter cartridges.

Overall a very good video thank you for your depiction however the note should be added about putting the antifreeze back in before you crank the engine

The oil pick up is directly under the oil dipstick. If you put a longer wire (than the dipstick) you think you are hitting the oil pan, but you are only hitting the oil pickup. You have to keep rotating the hose and pushing down until it bypasses the oil pick up and hits the bottom of the oil pan. I too was only getting a little bit out until I found this out. Keep googling the engine number and put in oil pickup and you may find it that explains it better.

I like the color of your hat but the flapping halyard is annoying.
