The boat Im still looking at is an 1989 22 foot sea ray OV which is a fairly large boat. A friend of mine has a similar boat and its powered by a 5.7 L motor with 350HP... basically Im wondering is a 4.3 Litre V6 underpowered for a boat this large? I have 2 kids and the wife (plus all related gear that comes with them) so the boat will be heavy. opinins or advice would be appreciated. Thanks
