Just bought a boat that has a Yamaha HPDI 175 on it. What kind of matinence do these motor require. I've heard Yamis like their additives. Thanks in advance.

- Change water seperator filter every year.
- Change lower unit oil every two years.
- If motor is surging at top speeds change all filters; especially the hard to get to one that is internal over the carbs..
- Pull the prop. often to check for line.
- Put gas treatment in on each fill up.
- Change the impeller every 3 years; and water pump every 6 years.
- I am not a fan of Yamalube treatment and do not like any other additives.

Great engine, you will enjoy it and spend more time on the water because of your purchase.

I run both ring free and Yammie fuel stabilizer. Cheap insurance in my opinion. Mine has been trouble free for three years with 120 hours and is stingy on the oil.
I only use Yamalube. I buy in but at the dealer for $22/gallon. At a 50:1 ratio that is over $125 in gas for every $22 in oil.
