Correct me if I am wrong, but I know of 2 502 motors. One is mid 400HP and the other 502 is 500hp.
I think you will be just under 70 or at it.
I had 400hp on my TRP (very heavy layup) and hit 60.

Depends on which 502 you order. The 502/502 is over 500hp. The regular 502 is 410. The 502/502 will get you right about 70. The regular 502 will get you low 60s. I have one we will be finishing this week with the 502/502 if you would like a ride.

OOPS! sorry, didn't see the "deck boat" part...should be over 60 with 400hp and just on top of 70 with 5o2/502..
