150 HPDI Maint. Tips

[mwenger1]

My 2004 Hpdi 150hp runs great. I have 750 hrs on the engine. I do all the maintenance myself (plugs every season, lower unit oil, change all filters) Does anyone have any suggestions about additional maintenance that I am missing to keep it running A1.

Your owners manual has a maintainence chart in it that helps to see what needs to be done.
If you don't have the manual go www.yamaha-motor.com you can view it online.
