BBC w/ full A Impeller

[SD MIKEY]

I have a BBC which I'm told is 330hp and a full A impeller. The boat is a XT20 open bow. Have any idea how fast it'll go?

My guess would be about 60. I'm sure you know that the guys here can help if you want more!

Well, it depends on how tight is your pump?, how straight is your hull?, yada, yada, yada. Even then it would just be speculation. Buy or borrow a GPS and you will know for sure. It will be a humbling experience.

My dad's 92 Caribbean 20.5 open bow with a 330hp 454 and a berk JG with diverter and wedge would get a best of 53mph via GPS with full tanks, 3-4 good sized people, cooler, and all of the usual safety equip. The bottom on that boat was the same as that on most of the cal-custom 20-21' BRs from the late 80s to mid 90s.
Good luck,
