any one know the model number of the side power bow thruster on the 33 express

Pretty sure it is an SP55 if memory serves. GW customer service could confirm.

I can confirm that my 2003 has an Imtra SP 55 which I believe is original.

Incidentally, if you still have the original gear leg with the external lubrication tank, you might consider replacing with the newer sealed gear leg which does not require oil changes. The new one will also fit the newer 5 blade props which are supposed to be more efficient and quieter (I didn't really notice that much difference)

Change the zinc every year. I've seen plenty with missing blade(s) because people don't change the zinc enough/at-all.

Definitely an SP55.

How easy of a job is it to change the gear leg?

My marina did it. I don't think it was particularly difficult...
