Some helpful tips to help when purchasing a short block or long block replacement engine.
    
   When it comes time to replace your worn or broken gasoline engine there are a few things to keep in mind.  If you get these right then swimming through the endless supply of internet suppliers who just don’t know will become much simpler.  You also will find that the change of the engine parts will go smoother because you bought the same model you removed.
   For example; the GM 350 cid or 5.7 liter engine went through several changes that could have a dramatic impact on a change.  In the early days the engines were equipped with valve covers that had perimeter bolts and a 2 piece rear seal.  The heads came in a couple of varieties as well.  And the intake was held on with 12 bolts (6 per side) that all went in at the same angle.  Today the valve covers are held down with center bolts, the engine has a 1 piece rear seal, the intake uses 8 bolts (4 per side) and these bolts go virtually straight down.
   This is important because all of the parts that may need to be changed will not bolt on if you have selected the wrong replacement.  Parts such as the intake, flywheel, fuel pump, water pump, harmonic balancer, brackets and more.  So,in short, make sure you have some very basic information about your engine and the change will go much smoother and in the long run cost you less money.

   For starters have these basic items at your fingertips.

1. Year Model
   As with everything built in yearly productions the boat’s year may not match the engine’s year.  So there are differences that will help narrow your search in getting the proper replacement for your engine.
2. Engine Size
   The engine size or cubic inch displacement.
3. Horsepower
   The advertised horsepower.
4. What Company Built the Engine
   The marinization company, i.e. Mercruiser, Crusader, PCM, Indmar, Marine Power and such.
