The current vB forum software version doesnt support subscribing to manufacturer forums or major forum sections, like Mercury Outboards or the Restoration forum directly, only individual topics can be subscribed to.
Unfortunately, the notify for subscriptions is often hit or miss.
your best bet is to bookmark the Starcraft forum and check it occasionally
or bookmark the Today's Post list amd check it every 24hrs. This a running list of posts over the last 24hrs, listed w the most recent listed at the top.
and please remember Iboats doesnt have a swap, used parts, giveaway or for sale section
