Great job Wim! Man you're allround. And you've got the tools bro! Love the sound of the 1 cilinder

[@DoubleUThings]

Hahaha! If you need to do everything yourself, you automatically learn how to do the jobs :D And yes, that 1 cylinder - it looks like every boat we buy, has at least one of those!

[@Capfka]

Nice job, Wim. Impressed with your know-how and brother in law!

[@DoubleUThings]

Haha, well, nowadays you can get a lot of know-how from the internet (read: KZbin), but I have had a mechanics education long time ago, so there are some things still lingering around in my bald head :-) And my brother is a real mechanic, so always handy!

[@pauldhond4974]

Hey Wim, this repair was already a few months ago for you. My Yanmar 1GM10 also leaked oil from the head just like that. Your video was very inspiring and helpful in doing this job myself. Thank you. Keep making nice videos of your adventure with Anja. Thank you.

[@DoubleUThings]

Hey... I already reacted on your comment... Strange. So, again :-) Glad that our video was helpful! Good to hear. And yes, we will try to keep making these videos. although I hope it'll be more sailing and exploring videos than repair/refit videos 😁

Yanmar 1GM10, lovely little engine!! Very trust able and reliable

[@DoubleUThings]

True story. But some extra hp's would have been nice :-)

[@MonkPetite]

Ahah You have don that before.. top job ! Nice instructions. Lovey engines , they cant go bad if proper maintenance is preformed. A little tip is not to use “kroonstenen” They are in most cases the cause of trouble. On a starter system the wires and connections are kept simple and direct. Use krimps and solder to make it perfect. The reason is that if the battery is low on voltage and you start the engine the amperage is humongous high. That can cause the connection to overheat. A fire hazard is imminent. But nevertheless awesome job well done. My respect to you sir

[@DoubleUThings]

Yeah, kroonsteentjes are causing a lot of trouble. I am going to order a new wire. I have to rewire lots of things anyway. But too much work left to do that right now.

Es molt instructiu i encoratjador! Quina moral! Resolguent tots els problemes que te van surgint!

[@DoubleUThings]

Gràcies per les vostres amables paraules! :-)

Tenc un veler Gibsea 26' amb un Yanmar 1Gm10 i tenc la culata desmontada per falta de compresió. Aquest vídeo m'ajudarà a montar-lo.

thank you for this great video and smile

[@DoubleUThings]

You're welcome! :-) And thanx!

Hey, I just watched your engine video with great interest. I have 2gm20's and they were both completely ceased when I bought the engine. They are almost identical to your 1gm10's. To cut a long story short, I have rebuilt both of them completely over the past 2 months and finally have them running nice. Your starting problem, I had exactly the same problem and like you I pointed at the ground, the batteries and the starter motor. After messing around with everything I was still suffering intermittent starting problems and couldn't work it out. In the end it was actually the gear selectors that were at fault, you wouldn't believe it but they have a cut-off switch in them that prevents the engines being turned over if you have it in gear. Of course you wouldn't have tried to start in gear but the small pressure switch on the underside of the selectors sometimes stick and prevent you from turning the starter motor. If you take a look at the back of the start panel and trace the wires coming from the start switch you will see it runs to the gear selector and then off to the starter motor. Simple fix is to remove the pressure switch out of the circuit. Took me a week to find this problem, I thought I would share this with you and hopefully save you a headache. Hope this helps ;) Peter s/v Savanna Blue

[@DoubleUThings]

Thanx, man! Those kinds of tips can spare someone hours and hours of headache when trying to solve the problem (how long did it take you to find that out? :D ) Hey, but nice if you can get things running again that other would love to throw away, huh?! Happy greetingz, Wim

[@peterharrison8924]

@@DoubleUThings It was a week of searching and diagnosis. without looking at the selector you would never know its there. Looks like you got to the bottom if it. 1GM's are a great engine, simple and straightforward to work on. Keep up the great videos, we watch every episode :)

[@DoubleUThings]

@@peterharrison8924 Haha! Me too, before I upload them :D Happy greetingz, Wim

Nice job!! Wat een mooi geluid he, zo'n lopende moter na zo'n project 😁😁 voor heel even dan. 😜

[@DoubleUThings]

Twee lopende motoren zelfs! :-) Heel even? Heel even?! Oh ja, valse start, haha!

Nice job bro! Lucky you to have such a technical brother.....! 🤓😜

[@johnhillebrand8439]

check the head bolts after several hours of motoring. some head gaskets need to be re tightened . Groeten uit Holland !

[@DoubleUThings]

Dat was het plan, ja :-) Voorlopig, ligt hij echter nog wel even aan de kant (na twee zeer korte tochtjes), want hij is nog niet klaar.

[@alexanderdempsey1786]

Great job!

Thanx! :-)

good job,, thank you ,,i have the same engines in my cat ..

[@DoubleUThings]

Thanx, and you're welcome . They are a little small though, huh? :-)

[@roderickmchardy3650]

@@DoubleUThingsi find they are good enough ( on my 36 ' 3.5 ton cat 6.5 knots ) super smooth and reliable and VERY economical .

@@roderickmchardy3650 Yes, economical they are! But our cat is two times more heavy :D Officially 5599 kgs, but with everything in it probably 7500...

Je zal er maar weer verstand van hebben. Mooie cursus in beeld. Klasse gedaan!

[@DoubleUThings]

Al diende leert men, zeg maar :-) Danks!

[@hellohellohello6847]

Hello, I’m doing mine, but on the head gasket it looks like the waterways are blocked off on the gasket.. is that right?

[@DoubleUThings]

Yep, that's right. Keep it the same. It is strange indeed! :-)
