What was the final year that Yamaha made the 3.1 vMax 250hp fuel injected motor? Was this a good reliable engine? What to look for when purchasing? What are annual maintenance things to do outside of normal impeller, lube...?

What was the final year that Yamaha made the 3.1 vMax 250hp fuel injected motor? Was this a good reliable engine? What to look for when purchasing? What are annual maintenance things to do outside of normal impeller, lube...?
I'm thinking 1999. The Vmax are reliable motors and maintenance cost is cheaper then the HDPI. I have a 2004 vmax 250. annual maintenance lower unit oil, water pump, Clean O2 sensor once a year, vst filter, clean poppet valve, spark plugs. Parts are still available from sims and boats.net
Easy to do the maintenance....
I would say 2004. in 2000, 225 was the biggest ox66
I meant 04 last year of vmax
I have a 2004 OX66 250.
Yep 2004 ox66 250. powerhead I am running. great engine, keep injectors clean and vst filters clean. Maintain the o2 sensor and keep draft tube clean and your normally set. Best mod you can do is replace the failure prone diaphragm pumps with a electric fuel pump.
