Rob, I gave the wrong part number.
The correct one should be 391073900

Installed the vacuum gauges, reading normal
Check engine rpm reading on Smartcraft with handheld tachometer – results 2 rpm difference.
Check gearbox output shaft rpm with handheld tachometer -less than 0.3% difference.
Pulled out the prop to check the pitch by the prop shop that re pitched the prop – result – both prop has same pitch reading
Not happy with the prop shop, went to another prop shop – pitch the same but the cups on the port side were missing!
Added some cupping to props but prop shop guy says he can’t measure the cups best he could do was eye balling the cups.
Result of the cupping – port engine now loading more and starboard engine running cooler.
The differential fuel consumption between both engine at WOT Port 62 Stbd 67.
Ordered a pair of new props from Nakashima..hopefully it will improve the performance.

Tony,

Thanks for the reply. With the present prop at WOT 2870 rpm.

I prefer the actual consumption figures to be below factory rating too.

Will swap fuel lines between P n S

Have not done vacuum test on the fuel line. If I draw fuel from the line the fuel will continue to flow, how to do that test?

The fuel water separators and inline fuel filters were changed recently, about 5 running hours ago, the result are the same.
