Viking/Merc 175 Setup

Randy,

I am going to probably purchase an 81 Hydrostream Viking with 81 175hp mercury next monday and would like some advice since this is my first outboard boat.  I am buying the boat from the original owner and the boat is stock except for having the floor replaced, the cables changed, some brand of nose cone, a hydraulic jack plate (don't know the set back yet) and some aluminum prop of unknown dimensions at this time.  I will primarily drive this boat with my wife and we like to go fast safely, so I would like some recommendations on a prop that will not see skiers, but could have four people in the boat at one time. 

I have not yet driven the boat but the current owner talks about a lot of steering input to correct the boat at speed.  Should I look into solid engine mounts?  What else can I do to the boat to make it more user friendly.

I also would like to do some engine modifications and I was wondering what I should inspect first for wear and what order the modifications should be done in.  I would like to do small things like compression, reeds and maybe some exhaust.

Finally what do think the boat should run as purchased with a good all around prop.

I am sorry some of the info you need might be missing since I am new and do not have the boat in my possession yet.

Thanks in advance,
Jim Stevens

 

Most V-Kings with a 175 and 26 chopper prop would run 75 mph out of the box. Start there - modifying an 81 engine is not going to be very cost effective. It is probably tired and modifying it would seriously affect its life span. If you rebuilt it then ok, but for that cost you could build a newer engine. Take it out and enjoy it. Find a chopper prop and see how far that gets you toward your goals.
