Degree wheel?

[Gary pope]

Does anybody know what degree to set the rotary valve on a 95 657x motor for my speedster?SBT told me that they don't have manuals for jet boats they just do jet skis so that does me no good. Which is kind of ironic because that's where I got the new motor from was SBT.

147 degrees at opening. 65 degrees closing.
That's for all 657x.

I seen that same shirt before but I don't see speedster on there anywhere

A 657x is a 657x. They all time the same.

I don't see anywhere on that chart where it says anything about motor size though.
