Yamaha F115 Maintenance 101

[triumphrick]

We have had this boat a week, and while we tested it I noticed the waterpump was a little weak, not a strong tell tale. Also wanted to spend some time getting used to these motors, so thought an oil change, filters, lower unit oil, waterpump kit and a general clean up and remove some corrosion and rusting of some bolts. Sorry for the quality of the pics, camera was in need of new battery and I really wanted to get done, but chronicle some of this as I went.

After searching many posts, I decided to change the motor over to Castrol Syntec, synthetic. They are long out of warranty, so I don't expect Yamaha to care what I run in it. I am also a car guy,old British roadsters, and have been using Castrol since the 60's.

I also like a clean motor. That's the reason for the brush, WD40, and pics of the flywheel. I also like having a liberal dose of Yamaha marine grease on parts of the motor at the waterline and on some inside parts. Specifically the tilt motor and the mounting bracket. After applying, I wipe off the excess, but like a liberal film. I dont use silicone, i use WD40 inside my motors. My first new motor, an '86 Yamaha 90 served me well for 10 yrs. with no electrical or mechanical problems whatsoever. I am a firm believer of a dose of WD and also of running the carbs empty as well after flushing the motors. Nowadays I use Salt Away as a final flush.

Here is a photobucket link with titles under the pics...taken in order of repair..
