(Compiled by Jim Poel)

Below
is a list of known "337" forms for the Republic Seabee. STC's are also added where available. If you have any
additional 337 forms that are not listed here, Jim Poel requests that you send
them to him (or me) and we will list them here for all Seabee owners to take
advantage of. An older (but still acceptable) list of STC's is available here.
If
you would like a copy of the modifications listed below, please
contact Jim Poel at hjpoel@aol.com.
One
important safety note: Jim Poel has the modification to add
shoulder harnesses to the Seabee (Listed below). As you all know,
Republic was not required to have shoulder harnesses back in 1947 so
consequently Jim has taken it upon himself to modify the Seabee for
them. We strongly recommend that you consider such a modification to
your Seabee. They could easily save your life.
(Ed note: I have seen them personally and am very impressed with the simplicity and structural integrity of these shoulder harnesses. Steve M.) If you need a
Microsoft Word viewer (DOC), get it here!
