Tilt/Trim Screeching During Lowering Of 97 Yamaha 150

[jasonalden]

During our last outting I noticed a screeching while lowering the engine (sort of like a razorblade going sideways down a chalkboard).<br /><br />The screeching happens almost everytime the engine is lowered and only happens at 2 seconds after the outboard makes contact with the 2 lower rods. After 2 seconds of pushing them in, a screech is observed for about 1 second then goes away.<br /><br />Why is this happening - are these rods supposed to be lubricated? If so, they are not; Although they appear clean, they are completely oil free. <br /><br />Do I need to get some grease on them, if so what do I use? I have a new tube of grease with teflon...would that do? Do I just smear the grease on the rods?<br /><br />Thanks again.

friction, I hate that sound.<br /> scratches or any damage to shafts would indicate further damage of trim unit itself. <br />if trim fluid level is correct and there's no damage to them a light smearing grease is ok but as motor is tilted it will wipe most away so dont over do it.

grease my man grease<br /> its called maintenance.<br /> wipe some good yammalube grease on the tips of the ram as well as the wear pads. its common.<br /> dont grease the trim or tilt shafts. the wiper will just wipe it off anyway.<br /> good luck and keep posting

Yamalube...OK..<br />This stuff? I see that there are a million different varieties of Yamalube.<br /> Yamalube® 2-M 2-Stroke Engine Oil Semi-Synthetic Injector Oil For Outboard Motors <br /> http://www.yamaha-motor.com/accessories/apscitemdetail/3/121/4039/801/1/detail.aspx

Go to additives and lubricants. Corrosion guard also works well. May be easier to find locally.

use yamalube grease or quicksilver special lube 101. both are very water resistant<br /> that is why I said "yamalube grease" to many yamalubes

OH OK thanks. I am new to all this stuff so I am a bit slow.<br /><br />Well, not reading your post yet I did put on some outboard engine oil onto the 3 shafts & the 2 ends of the lower shaft, and on the engine pads where the lower shafts contact and wella...the screaching is gone. I'll keep those shafts greased.<br /><br />THANKS GUYS!
