Default Re: '97 mercury EFI, good motor?

. . . at trolling speed approx. 1800 - 2000rpm I burn 3.5 gal an hour. I can't say I've ever checked how much I burn at idle. 3 gph seems high.
Just for reference, my E-Tec burns 0.18 gph at idle, and about 0.5-0.6 gph @ hull speed (~5 kts), ~ 1000 rpm. MPG drops real fast when I push it over that, so I either run 5 kts or put it up on plane at 20 kts+!
