spark plugs

[flippin21]

I own a ranger bass boat with a 250 HPDI 2005 model . How often should I be changing or inspecting the plugs ? Thank you in advance .

i do mine usually about 2x a year but really depends on your usage.

jb,
How many hours do your average in a year?

50 to 60 hours per season / usually by making 20 to 30 mile fot runs

flippin,
You should be able to go a full year on a set of plugs. My little C115 burns more oil than yours, and is not as efficient as your HPDI, and I go a year on mine.
