Yamaha 115 4stroke

[blakeb]

i Have a 2006 four stroke 115 yamaha, i was wondering do yall follow the factory schedule for maintance?

Do the valves need adjustment at any certain times?

And had anyone had a quiet yet high pitched squeal?

I have an 01 f115 that I have owned since new, and have done zero maint besides, oil changes and lower unit changes. I average about 100 hrs a year. Not a single problem with it. I called the dealer, they told me I should change the waterpump, and plugs, besides that, he said they have been a trouble free motor.

I havent done a thing to my 04. All I do is oil, lower unit, plugs and oil filter. I also run the ring free in my premium fuel now.

I am going to do a new impeller and maybe water pump just as a precaution.

[blakeb]

whats the scoop on the water pump and impeller? are they know to go bad, and are they easy to do?

[Ufatz]

Water punp/impeller could just be good preventive maintenance when a motor gets quite a few seasons/hours on it. Have a 2004 115 and it has never skipped a beat with just the usual oil and lower unit stuff.

An absolutely GREAT outboard motor. Mine starts so fast I can barely get my fingers off the key fast enough!

hey mine too, just want to make sure i am not forgeting something along the line, time for new plugs soon

And had anyone had a quiet yet high pitched squeal?

My '01 makes a sound like that but only at full throttle, so I just don't run it at full throttle - problem solved right

I'm assuming it's a belt or accessory bearing, I'm not going to worry about it until it becomes more common. Anyone else have ideas on that?

The squeal issue came up last year in June.. .here's a link to the thread:

I have an 02 since new and I did change the timing belt and impeller after 5 seasons, just as preventive maint. I ihink the timing belt is a recommended procedure. It has been and outstanding motor.

Thanks Marine Man I'll check it out.

At what point should a guy start running the Ring Free? I have a newer motor with about 25 hrs on it, I have had no problems and would like to keep it that way. What about going to something like AMSOIL?? I heard not to start with amsoil, but go to it later after motor is broke in a while..?

No problem to start with AMSOIL. Many 4-stroke outboards are started from new with synthetics from the boat manufacturer. With AMSOIL use the marine 4-stroke oil in your outboard - NMMA FCW certified - full warranty approved products: 10W-30, product code WCT or 10W-45, product code WCT.
