1984 Sea Ray Seadn bridge.
Engines
Twin 454 Mercruiser
I'm spinning 17x17 props, so I guess that’s what they came from Sea Ray with.

Power is 454/350hp

At 3000rpm I hit 22mph is this Normal cruising rpm / speed?

WOT is only 3500rpm seems low and it takes it's time getting there. It almost feels like the throttle cable stretched and I'm not getting a true open throttle. But I’ll check that later this week.

What’s the most fuel efficient rpm/ speed?
