I'm just guessing it's a Sanger, by the way the pump is mounted.
I know Sanger did this, but did any other builder go this, I don't know.

thanks!
we actually bought it almost completely casco (only the berkeley was in it)
and completely built it as it is now.
the previous color was bronze/gold with flakes.
what do you mean by the way the pump is mounted? we actually have some issues with the boat handeling.
maybe it has something to do with that?
if we try to make speed (just over 2400rpm) the boat suddenly starts swerving to one side (could be left or right, not just only one side)
maybe someone has experience with this?

Looks like a 60's style flatbottom jet. That was before hull ID numbers, so it's hard to say who the builder was.
As far as the boat tracking left and right. Looks like the pump is high off the bottom of the boat because of the flat bottom design of the hull.
This makes the thrust line high, which pushes the nose down. That hull has a deep entry nose, so it's tracking back and forth. Need to get the nose up.
How are the plates on the back set. If there flat with the bottom, raise them and see if that helps.
A wedge to change the angle of the nozzle will help push the back down and raise the bow.
A place diverter would do it also, but more expensive. Maybe a droop to lower the thrust line, but I would start with the least expensive changes first.
Have you checked to see how flat the bottom of the boat is? If it has a hook in it, that will push the nose down causing it to track.
Be careful, at speed if the nose catches it can spin out.
Keep in mind these are just my opinions.

thanks for the input!
we will raise the plate at the back first, hope it helps.
we never made real speed, probably 30 mph max, i have a video of the boat behavior maybe i can post.

i forgot to say we also got a berkeley rudder on it.
maybe it changes something
