So been kicking this around in my head
Some believe the SHO is a short term engine?
Will be interesting to see who has the most current hours on their engine and the way it has been run and serviced.

My 2011 motor has 750 hours. runs like a raped ape. I have done all my own servicing on it(had it for 6 years now). Replace the oil, grease, plugs, filters at the end of each season. I make sure it is thoroughly warmed up before putting on plane, don't run wot that much.
The power head was replaced at 180 hours for the oil seal retention recall.

Mine (2011) has 950 on the ECU. Short block has been seen replaced 3 times under warranty, last one in 2014 with 348 hours at that time. Yamaha said it should be bulletproof with this block and it has run flawlessly since then. Last time I checked the hours (last week) it had 592 hours on this block.
Still runs as strong as ever, and no hiccups. New lower unit replaced in 2014, fuel pump, and other stuff.
