Just purchased a Maxum 3000 SCR. Was a little apprehensive purchasing a 23-year-old boat that went out of production for 24 years. Have been browsing and asked a couple questions. Found this group to be very informative and helpful.
Maxum was manufactured from 1988/1989 to 2009 (roughly 20 years). They stopped manufacturing the line 15 years ago.
They manufacture the deck and hull and marry the two together. The rest are 3rd party parts installed by Brunswick. Think of all parts other than the deck and hull as replaceable with each having varying and unique, yet limited lifespans.
Deck and hull are still serviceable. None of this is unique to Maxum and applies to all boats.
