unequal fuel consumption

[jchoe98]

need advice. searay amberjack 290, V-drive mercruiser 350's. fuel injected. my starboard engine consumes nearly 1.5 times as much fuel as my port engine. also, if i troll at low speeds, the starboard engine stalls after about 15 minutes of low rpm/idle. i only have about 90 hours on the engines.
any advice? :huh:
i run them at same rpms...

1.5 times? If you run the genny, it pulls off of only one tank, so that could be the problem, but no where near 1.5 times...

What are the WOT RPM's?

interesting that you ask...the starboard engine WOT is less than the port WOT rpm, but about 300-400...I did have an issue with some water leaking and they had to fix it by replacing some coupler (I assumed it had something to do with what keeps the water out of the bilge where the shaft exits...maybe i'm onto something here...) no generator...
