Awsome video!!! You helped me more than you know! Thank you.

Mejor explicado mi amigo pete nadie gracias nuevamente por enseñarnos tus conocimiento son de mucho valor para tu seguidores aprender saludos desde 🇵🇷

Thanks so much sir. I very interested.

Nice work ❤

MAKE SURE TO SLIDE THE BELT DOWN LIKE IT WAS ORIGINALLY AND rotate the flywheel in a clockwise direction, this will tighten the belt on the port side and slack it on the tensioner side. Tighten the tensioner bolt to correct torque while holding at the flywheel.

In Sweden We just say Kaaanoon! It means fantastic!🤩🤩🤩🤩🤩

Nice detailed video. I'm working on a 75 merc right now that is the same powerhead. Merc by yamaha , lol

Thank you

I did like the tip with the Woodruff key

Muchas gracias por contestar, el motor que me refiero es YAMAHA F115AET L año 2000, reemplazó de bomba de combustible de baja presión y de alta presión . Atte Miguel

Comme d'habitude, parfait ! Merci Monsieur

Ganhou mas um escrito! Ja cheguei comentando se escrevendo e dando o jóia.

Very well done. Thank you. Noticed at the 20:33 mark when you pulled the clamp off of the flywheel, the belt got tighter and the tensioner was moved. Did you just apply more pressure on the tensioner and tighten it down? Or is there another trick?

Thank you sir super explain and slowly speaking is good I am interested that's good and camera focus good also so good ❤ thank you for the information ❤ next video upload I am working for Maldives speed boat but working I don't know next video ful sensor video upload please sir how to check the problem in computer and OT find out and how to problem solve. Please help me sir I kindly request 😢😢😢 thank you sir ❤❤❤

I’m assuming this would be the same on the 150hp. I have twin 2005 models. What are signs or symptoms the belts need to be changed? I’ve owned the boat a year now and they have right under 600 hours on them. Not sure if they have ever been changed. They look to be in good condition. Excellent video and explanation step by step.

Great video. If you get a chance to video a 2.8 200 timing belt replacement I'd greatly appreciate it.

Hola muy bueno , tienes video de cambio de bomba de combustible. Muchas gracias

hola buenas noches muchas gracias x la informacion y la guia q nos brindas saludos desde CostaRica, Pura vida 1na consulta si 1no compra partes de los repuestos en Amazon son confiables o hay q comprarlos directamente cn la agencia Yamaha?

Hi - do you know how hard it will be to lift a Suzuki df 140 lower unit by hand because tilt motor is out. thanks

I feel the belt is loose as when you removed the clamp it lost tension. Overall nice information. Thanks

I am Indian from tamil nadu please sir slowly speaking ❤❤❤

👍👍👍

Is the belt tensioner bearing supposed to be able to flex back and forth so the spring keeps the right amount of tension or do you set the belt tension by how much pressure the spring is doing and then when you torque down the bolt it holds the bearing in place is the bearing supposed to be able to move?

Hello sir, I have 150 yamaha 2 stroke hpdi . Cranking they have spark 2&3 but while engine running no spark.

As far as making sure the correct tension is on the timing belt, is it only that spring that’s giving the correct tension and then tightening that nut to keep that tension?

Hola es un motor YAMAHA 68V - F115AET L MODELO 2003 de 4 tiempo.

One more question. Can't I just do my two rotations with the old belt to see that it is in timing and then bring it to TDC, ensuring the arrows are pointing on the camshafts? Also placing a camshaft locking tool. Then remove the old belt and install the new one? Then I guess I would rotate the engine two times with the new belt to ensure that it is in correct timing, and wham, all is in timing and good to go. Wouldn't all that work that way also? I have to get a new camshaft locking tool, as the one I ordered off of amazon won't fit between the camshafts with it's teeth. I imagine it is for a bigger engine, then the 115. Reply

Saudações Nobre Amigo! Também atuo nessa área, Sempre aprendendo Mas. Um abraço, teria Vaga de trabalho por ai pra mim falo do Brasil Nordeste.

Hola , es que es un motor que hace 8 años que está sin funcionar, y quiero ponerme al tanto para hacerlo funcionar. Tienes algún consejo al respecto. Muchas gracias

Quick question. I am wanting to change out my timing belt and i was a mechanic in the coast guard but i never did change out a timing belt. the service company wants to charge around $700 or so and after purchasing some of the items needed for this project and the timing belt, it could cost me around $180 to do it myself. Anyway, my question is, if I don't get the timing exactly right for whatever reason and I test ran it in my water tub, what is the worst that can happen to the engine? am i going to bend valves or destroy anything if i wasn't perfect on aligning? I'm sure I'll get aligned but i always like to know worst case scenarios prior to getting involved with any project. Thanks,.

Hola un cordial saludo sería tan amable de decirme donde están ubicados ustedes gracias

Battery is good Nutter position self moter is good but engine is no starting what is the problem tell me please help eny video

Hola! Como podre comunicarme con usted? Tengo unas dudas de como quitar la cabeza del motor de un yamaha 115 nuevo para cambiar el bracket swivel (soporte giratorio) necesito su ayuda!

I lost both my stator aligners. How screwed am I?

Turning off the 12 volt power would have been a good idea. When he pulled out that remote starter switch and I realized that engine was live the whole time he was working on it... 🙄

No need to do all this steps. Align the flywheel to the TDC mark before removing it and check the cam marks. If they are correct don’t move anything. Replace the belt.
