I'm about two to three days away from delivery of a 2005 Searay 185 O.B. Sport, with the fish and ski package. This was a Boat Show purchase at around $19,000.00. It included the Merc 125 Optimax outboard motor. After speaking to a few fellow boat owners I got less that stellar comments about the 125 motor. Seems most of them suggested going to the 135 or even up to the 150 Merc's. We'll be using this mostly for pulling skiers.We may have two College size boys, both probably on one ski. Any one have any feed back on this engine. What would be a normal increase in price to move up in size
