I will be picking up a 2013 ZX190 with a 175 HPDI. Im coming out of a 2000 SX176 that has a yamaha 115 4 stroke. This will be my first time with a 2 stroke and I have some questions.
1- Do I have to run the yamaha ring free. In the 115 I used Sta-bil
2- At what RPMs will the motor get the best fuel mileage
3- I never had to worry about water pressure. What number will I want to keep it at when running?
Thanks... Im sure I will have some more question after I pick it up.
Ring free and stabil are not used for same purposes, yes to using both. Not required, but highly suggested.
Boat does good around 3,500-4,000 for mpg
15psi min on your guage.
should I use the oil yamaha says to or is there a better choice.
Ring free and fuel stabilizer every fill up. Make sure to change your main filters and plugs every year and you will be a happy HPDI owner.
Yamalube is dirty. I switched to Pennzoil premium plus.

Would it be safe to mix the Pennzoil premium plus with what ever oil the last owner used. Or would I have to drain the oil out?
