I have a 90 290 enticer and have noticed throttle positon vs synchro guage. I cruise at 30 and when the engines are synchronized the throttles are pretty close together and the rpms are almost exact, now....when running wot the synchro guage shows one engine producing much more than the other (don't remember which one) Does others do this?? It don't really bother me, I rarely run wot more than a few minutes, but just curious what other boats do with the synchro guages at wot? When I run wot I don't worry about synchronizing them, i just push them all the way forward until they stop..Thanks for the info..

I would worry more what the tachs show and that both carbs are fully opened at WOT that what the Sync guage shows.
