I had the boat out yesterday, first time out this year.
Put some new gas in, but mostly last years gas (had been stored with fuel stabilizer), put some Merc Quickleen in.
2011 150 Optimax with jet pump.
Started great, bit of smoke on start up from fogging spray in cylinders.
Ran great, but I'm only pulling 4800 RPM max. Last fall, and all summer, my max was a hair over 5000.
Any ideas on why it might be running low?
Would the old fuel be a likely culprit? They are original plugs, but I only have maybe 25 hours on.
