1989 Larson Senza 210 LX speed

[crazygn]

I took the boat out for the first time today and had a oil leak, not sure if it came from the dip stick or what so i didnt stay out long. Anyway i dont know my speed but i run a 350 with proline heads and comp cam. It would only run around 4100-4200 rpm WOT does this sound ok or low. The prop is a rapture 1425R21

Anyone know the stock speed of this boat. It feels like it runs in the 45-55 mph range maybe

Use a GPS I doubt you are calibrated properly to feel the speed on water.

Haha not at all. Is there a calculator to set weight, prop size, and rpm to get your around about speed
