Thank you for the location of bolt number 8. I had the one under the trim anode. Missed the one forward of it
🙂Thats what we are here for!
Merci beaucoup ❤❤❤❤❤
Hi, where can I buy the angled impact ratchet attachment? Much easier to remove the lower unit bolts with an impact driver than by hand. The cavitation plate makes it hard to get in there.
Thanks for sharing!my 150 Yamaha 4 stroke makes a squeaky noise.im told its from salt getting in the shaft bushings? Do u have a video on that? Have your heard of this? I was told it needs to be cleaned and greased? I’m new to this motor. Can u let me know what you think?? Thanks
Squeaky noises in your Yamaha 150 4-stroke outboard motor can indeed be caused by salt buildup in the shaft bushings. This is a common issue, especially in saltwater environments, as salt can cause corrosion and build up, leading to squeaking and other noises.
Cleaning and greasing the shaft bushings can help resolve this issue. Here are the general steps you might take to address this problem:
Remove the propeller: Take off the propeller to access the shaft and bushings.
Clean the shaft and bushings: Use a brush and some water to clean off any salt buildup or debris. You may also use a mild detergent if necessary.
Grease the shaft and bushings: Apply marine grease to the shaft and bushings to lubricate them and prevent further salt buildup.
It's important to follow the manufacturer's recommendations and guidelines for maintenance. If you're unsure about any step, it's best to consult with a professional or refer to your motor's service manual.
Happy Boating!
Ok important info missing here about the chopsticks!
Are they wood dowels? And do they scratch the paint
Hey there,
As a well-seasoned mechanic, Frank has several tricks he has learned along the way that are helpful to him. He does know the exact pressure he needs to hold to stabilize the gearcase without scratching it. That being said, it is not recommended if you are not familiar with the technique. If you do decide to use wooden sticks to help you with this project, wrap the contact point with a microfiber cloth!
Happy Boating!
Hay ça va ❤❤❤❤❤❤❤❤
