Help! I recently received a 1991 Cobra 18' with a 1991 150hp Force Engine (Blown). My dealer has a brand new 1998 Force 120hp for under $5K installed. Is this a good deal? Is the 1998 120hp Force a good dependable engine? I'm told it doesn't even use oil injection...MIX!!!<br /><br />What do you all think???<br /><br />Thanks in advance<br /><br />
