Re: Thinking to buy a 2003 Trophy 1903 w/Mercury 125 Salt Water Version
The main thing is to pull the cover, do a compression test, pull the drain/fill plug on the lower unit and look at the oil, pop the carb covers off have a look inside the carbs, etc. etc. That motor should still look pretty shiny and new on the inside of the lid and there shouldn't be any milkiness to the LU fluid. As for the boat, not sure what year they became "all fiberglass" but if this one was pre-that, getting a couple of moisture readings would be a good think. If it was built with a wood transom, removing screws for the fish finder or a transom bolt will sometimes allow you to look at the wood itself.
I know this is a center console and mine is a walkaround, but I really like my 1802. I think they're similar hulls, and if so, you should like the way it carries itself on the water. Rides like a much bigger boat, imho. I have a Force 120 on mine and it's a 35mph boat, so you should see better results out of your 125hp. I've heard good things about those Merc's. Not sure of the price, as it seems a little high, but I happen to live in the "Land of the BOats" so that has nothing to do with your market. If you're in a cold-weather state, however, definitely keep in mine you're into the real "buyer's market" at season's end. Like Mi said, either get a surveyor or take someone that really knows boats with you and demand a sea trial, making sure that it lasts at least an hour. "Starting the boat on muffs" is a waste of time, when it comes to confirming the operation of an outboard. GOod luck, keep us posted and don't forget the golden rule; "Pics or it didn't happen"
