10 hour service on Yamaha 115 & T8

[reelfine]

I up for my 10 hour service on my Yahama 115, and my T8 kicker. I called my service dealership and they want $225 for the big motor, and $90 for the little (plus tax and parts).

This seems pretty darn excessive for what amounts to an oil and plug change. If its just oil and plugs mainly, I can handle that myself.

Is there really any more to it, or should I just go ahead an take care of it myself? Would doing so void my warranty at all?

Do it yourself. When I had mine done about a year ago the only thing they did was change oil/filter and lower unit oil. I didn't get charged because when the boat was delivered the tach was not operating because they had it set for a two-stroke instead of a 4-stroke. They did list the price on the invoice which as I remember is close to what you are quoting.

I live a four-hour tow from my Yamaha dealership. They encouraged me to do the 10-hour job myself. Told me to change upper and lower oils, and all the plugs on my 115 and my 8. They did say it would be ok to save the plugs as back-ups in case I had a problem with one before the 100-hour change. So, they're in my spare parts bag labeled 10-hour plugs. I don't expect to ever need them, but they don't take up much room. The only hitch you will find is that it isn't easy to drain the upper oil reservoir without creating a mess, if you are doing it alone. It really is a three-handed operation! Save that $315 for fishin' bait and a new rod.

Thanks, good to hear that people are doing it themselves. I am guessing that at this point in the motors' lives, they don't need a compression check (they had one when they were new), or anything like that.

I think I will take your guys' advice and do the oil/filter myself.

They want spark plugs changed at 10 hours on a fourstroke?Why???

[Draggin' Bait]

Not sure why, but the official break-in period for a Yamaha 115 four-stroke is ten hours of controlled low and high-speed runs, followed by the procedures outlined above. After that every 100 hours. You can bet after spending the $ to get the thing I wasn't going to risk my warranty by not following directions!
