Have you seen a good/new impeller? If it looks and feels nothing like a new one, replace it. The oil cooler needs to be clear of any obstructions.
Who did you buy the boat from? If it was a dealer, they should go out of business.
Don't take it personally, but I would recommend learning what is needed to keep a boat running before taking it out. It's not like a car that can be driven day in and day out, without a thought as to maintenance. If you don't have an owner's manual, get one.
BTW- as great as the LT-1 is, I would hesitate recommending one for someone who is new to boating and/or isn't knowledgeable about car engines. You don't want to overheat this engine or idle for too long because the heads are aluminum and expensive to replace. Also, this engine needs premium gas, preferably without ethanol.
