Yamaha F115 (2003), noisy Trim&Tilt

[bossee]

Hi,<br /><br />I have been using a Yamaha F115 4-stroke (2003) for almost 3 seasons now.<br />This outboard runs fine but it has been a problem (ever since it was new) that when using the Trim & Tilt it makes a horrible noise initially.<br /><br />It is like this:<br /><br />When I'm going for a trip in my boat and start to use the Trim it is very loud (up or down) - it sound like: i i i i i i i i i i i i i i...<br />After I have cycled the Trim up and down maybe 4-5-6 times it usually gets quiet and works rest of the day without any noice.<br /><br />I guess it has something to do with the hydralics. It is when the upper part meet the trim pistons (see picture below, red arrows) the noice will start.<br /><br />Sometimes the passengers gets very worried when they hear this noise (if I have not prepared them it will be loud) and I have to tell them that "this is normal" (at least all works without any problem) but they usually do not look that convinced...<br /><br />Sure I can ask my Yamaha dealer but I think I will get better answers here actually.<br /><br />Anyone else with this problem?<br />Suggestion(s) for a solution?<br /><br />Thank's<br />/Bo<br /><br />

put grease where the arrows point. its friction between the striker plates and the trim ram ends.<br />normal service requires lubrication at this point.

Hi,<br />Thanks BenC and Rodbolt.<br /><br />When I come to think about it it was som grease (almost like glue) on top of the trim pistons when the outboard was new. It was gone rather quick.<br />I have so far had this outboard serviced at a Yamaha service center 3 times but they have so far never greased this.<br /><br />I did not know at all this is a thing to grease and not every week or similar of course. I guess I need to have a water resistant grease in my boat from now on.<br /><br />/Bo

I have a 150 that makes a weird noise sometimes too. I was told the new 150's have a weird sound to them and it's normal. I should try the greasing and see what happens.
