I recently purchased a 1989 30 Hunter in Fl sight unseen. I took a chance buying and paying for the boat with out seeing it. Very happy with the boat and the couple who sold it to me, they could not have been better people. I decided to name the Boat "Blind Date" for obvious reasons. Just today i came across your video and surprise surprise... Thanks for all the great videos!!
@@alexanderfernandez-n5f Lol! My origin story is a little different. I met my wife on a blind date 34 years ago. I hope you enjoy your Hunter as much as we have. We just came back from sailing to a nearby island for a week and will be going again in September. We are not your typical boat owners. We still get a lot of use out of our boat after 20+ years. I have a couple more videos to post on Spain, but after that I’ll post 2 videos on boat maintenance that you might be interested in.
@@tcsadventures Hunter 32. I have the same engine and I have to do all the things you describe in your videos (impeller, oil, filter change). Your videos are so helpful. Thank you so much for making them. You saved a damsel in distress! 🙂
Getting comments like yours make it all worth while. Thank you for your kind comments! I hope I have so other videos you enjoy! I’m actually on my boat right now about to go paddle boarding…
Cheers bud, just about to change the impeller on mine (same engine) have noticed recently that occasionally the water pump isn't turning when I start her, usually corrects after a few seconds, likely belt slipping or gunk in the impeller i would imagine but I'll figure it out
Will do, need to do the fuel filters as well but nervous about airlocking it, watched your vid on the filters one question does the pump run (to bleed it) with the keyswitch on or do you need to crank the engine with the compression levers open?
Mine has an aftermarket electric fuel pump. So, I just have to put the key in the on position and it pumps the fuel. I do not try to start the engine. If you don’t have a fuel pump you have to use the lever on the side of the engine. I think I show where this is on the engine. It will require a lot of pumping unless you fill the 2 fuel filter housings with clean fuel - then you won’t have to pump in as much fuel.
@@tcsadventures TBH i was just gonna open the decompression valves and shut off the water inlet then fire the start button for a couple of cranks rather than manually pump it
I’m not a professional mechanic and I try to share with other DIY people the safest least complicated way to do the maintenance - to try and avoid mishaps. But obviously it isn’t the only way. Good luck with your project!
thanks for the tutorial.. I have to change mine this weekend. Do you know of hand the part number for the belt that goes around your alternator as well and how often should you change that belt
I have a Yanmar 2GM20F. The “F” designates that the engine is cooled by both raw water (sea water) and fresh water. If you don’t have 2GM20F you may use a different belt. My belt is a Yanmar genuine part 25132-003700. I would call a Yanmar dealer to make sure you get the right belt for your engine. I think the number of hours you operate the engine and the climate you’re in would be factors in how long the belt lasts. I look for cracking and wear on the edges. If you’re in doubt I would replace it. It’s inexpensive and easy to do. If you have any doubt about repairs on your engine I would have a good diesel mechanic look at it and or talk to tech support at Yanmar (or authorized dealer). Good luck! Here is a link for the belt: www.dieselpartsdirect.com/ym25132003700
I can only speak from my personal experience. My Hunter is a 1991 and I’ve owned it for 23 years. I haven’t had any problems with my Yanmar. I think most diesel mechanics would say that 2 of the most important maintenance issues for a diesel is clean air and clean fuel. Keep the air filter clean and your primary and secondary fuel filters changed according to the maintenance schedule. I probably don’t put 50 hours on my engine a year, but I change the engine oil, oil filter and fuel filters every year. I change the reduction gear oil probably more often than I need to. Regularly inspect the raw water pump impeller and replace as needed. Of course there are lots of other things to maintain and some complex work you may want to have a professional do. But Yanmars are reliable popular engines installed in many high production boats and farm tractors. If you take care of it - you should have years of trouble free use.
I haven’t heard of it, but that doesn’t mean it isn’t a good idea. Does it work for you? Does it make it easier to get off when you replace the gasket?
FYI: the part numbers were displayed on the video at 9:01 and 9:20. Impeller: 124223-42092 & Gasket: 124223-42110. I didn’t include a link because these OEM Yanmar parts (for an engine that is no longer manufactured) can be difficult to find and sellers typically have a small inventory. So, the link would quickly be no good after I posted it (particularly if they’re from ebay). The vendor I bought mine from no longer has them. I just did a Google search and they’re out there at various price points. The non OEM are cheaper, but I prefer OEM parts. The OEM parts are in a distinct packaging that you can see at 9:01 on the video. Hope this helps! Good luck!

Nice walkthrough of the process!
Thanks for watching! I hope it was helpful!
Very nice tutorial; the only thing you might add that I notice is the torque specs for those who use them.
So wished I had watched this a few hours ago! Thanks for naming which sized sockets you used!
Lol! Did you just change the impeller? How did it go?
Excellent video and great explanations..Tk for taking time and efforts on our behalf. Grateful in Seattle Rick
I’m glad it was helpful! I hope you find some of my other videos you enjoy. Thanks for the comment!

I have a 1979 Hunter Cherubini 30’ with the Yanmar 2GM20F engine and your videos have been the most helpful to help me get started. 👍🏻
Thank you!

This one is definitely over my head a bit but interesting nonetheless! Lol
After you get your Jeep ... then a boat - lol!

We have a yanmar engine in our boat.
What are the usual problems i should be aware of with the yanmar engine?

Once again, a really good tutorial, grunts and all.
What's your thoughts on (waterproof) grease on the paper gasket before install?
I haven’t heard of it, but that doesn’t mean it isn’t a good idea. Does it work for you? Does it make it easier to get off when you replace the gasket?
@@tcsadventures haven't been game to try it yet, will feed back when I do. Thanks
Looks like he uses a 12mm and a 7mm socket
Please include part #'s and links

@@tcsadventures this is one of the most common engines out there pretty good availability IMO
