Reduced fuel economy

[Rz22013]

My 2013 RZ2 pcm ex343 is slowly getting worse with fuel. After prop and spark plugs what else should I look at/replace to help improve fuel economy?

No suggestions?

Oil change. Fuel control cell filter change. Are you running the same prop?? Add any ballast/lead?? Is you bilge staying dry or are you carrying around extra water weight. Those year shaft seal collars will walk up and leak at shaft.

Just out of curiosity, what is your metric for.measuring fuel consumption??

[Rz22013]

Nothing has been added but I also wondered about fuel quality. When I go up north I get better fuel consumption. Unfortunately I only go up with the boat once a year. Where I live is the reformulated **** but I'd have to drive an hour away to get the good stuff. I guess I could make a run to see if the gas makes that much of a difference. I understand there are many variables but wanted to see if I was missing something.

Thank you

Well I'm out of ideas then. I dont really keep track of fuel. It's just the cost of boating. Come jet boating here on the rivers with old carbed big blocks. 12-13 gallons an hour is good fuel economy lol

Oh I totally agree! I'm just making sure everything is in tip top shape. I'm anal about maintenance and cleaning lol

Did you change the prop? Your original post says prop and spark plugs??
If you changed props from say a 537 to a 1235 your rpm’s will shift at given speeds causing increased or decreased fuel “economy”

The fuel got slightly better with the new prop. I was noticing the decline before changing

What is your fuel economy vs what was your fuel economy?

[Rz22013]

So I filled up with the non-reformulated fuel and it made a huge difference. The gas around here is just ****, totally worth the hour drive for the good stuff!!

Nonreformulated? Like ethanol free?
