Top speed on the Z1

[Clug Z1]

I just picked up my Z1 last week and I am finishing up the 10 hour break in and haven't been able to open it up yet. Just wondering what top speed other Z1 owners are getting with the Indmar 350 5.7 / 350 HP.

Low 40's. Probably 42-43.

I typically see 40-41 with the same engine on a 1433 prop @ 5,400 ft of elevation. 5,300 RPM
