Bulletin No. SB-826 Shroud Group
SUBJECT: Securing sound blankets in shrouds; 1961 - 40 & 75 H.P. Engines.
Occasionally portions of the sound blankets contained in the upper motor covers on 40 and 75 H.P. engines loosen and must be recemented.
When this situation develops, sound blankets can again be secured by using 3M 1000 sealer which has in the past been, and still is, recommended to seal crankcase halves.
Because 3M 1000 sealer has in the past been recommended for use on crankcases, the majority of dealers and distributors probably have established sources of supply. For this reason, coupled with the fact that 1000 sealer in tubes is so readily available on the wholesale and retail market, this sealer will not be supplied as a service item by Outboard Marine Corporations Parts Depot, nor by Johnson Motors.
