The angles 31 and 32 are, as shown in FIGURES l,
2 and 3, connected to the bar 33 by means of angle stubs
38 and 39, respectively. The angle stubs 38 and 39 are
preferably Welded to bar 33 and the angles 31 and 32 are
connected thereto by means of bolts 40. The mounting
bracket 12 of the work stand 10 is bolted to the other 25
free ends of the angles 31 and 32. at the ?anges of the
angles 17 and -18 with the Work stand 16' extending into
the platform area de?ned by the pipe 33 and the bus 36

‘The pipe 33 is selected to be of a substantial length 30
so to remove the bars 36 and 37 fromv the immediate
board marine motors of a very extreme weight.
In view of the foregoing, it is clear that there has been
disclosed therein an improved work stand for outboard
marine motors which will permit the motors to be sup
ported at a comfortable working height and which will
permit the motor to be rotated about a horizontal axis
for the purpose of rendering ordinarily inaccessible pants
convenient for service operations.
In the modi?cation shownin FIGURES 7 and 8, the
support arm 55 is mounted across’ the top of a boat
transom 56 and secured thereto in any acceptable manner.
The Wedge shaped section 52 is held within the cavity
thereof. The motor mounting bracket is hung over the
top of the transom and support arm 55 and the clamping
screws of the motor are tightened against the wedge
shaped section within the support arm. The fore and aft
surfaces of the wedge section 52 diverge upwardly, so that
even if the boat turned over the clamping screws could
not slide over the thicker edges of the wedge material.
In this respect the support arm for the motor is identical
tween the horizontal bars 35 and 37 and the vertical
with that shown in the other views.
