i have the oppertunity to buy a 1999 mercury 90hp outboard for £4000.00 ( about $8000.00) i was wondering if any users of this engine can tell me if they are happy with theres and any problems that commonly occour with them, i currently run on a yamaha 90hp (1985)<br />the boat is a 16'6" phantom and used mainly in the north sea ( wooly jumpers required)for fun/ski towing ( incidently they have offered 1500 trade in on my old engine.)
