Vector/Merc 115 Prop & Ski Pylon

Randy,

I just purchased a 1976 vector with a 1978 115 mercury outboard (5500 rpm redline).  The boat has power trim and the rear seats are now facing forward against stern area where the fuel tank and battery are.  I was wondering if you could recommend a good ski pylon and where I might purchase it.  I feel like I have seen pictures of vectors with pylons that were located towards the center of the seating area with the supports leaning back and out towards the wings.  I do some slalom skiing but hope to primarily barefoot off this boat.  Would you also recommend a good prop for this?  Typically barefooting is in the 40mph range.  Finally, if you have any thoughts on what prop would get this boat to 70mph, I would love to have a second prop just for speed.

Thanks,

Casey O'donnell

 

Casey,

Any good ski pylon works (tri pod type ) and can be bought from most any local marine dealer. Overton's and such also carry them. To ski you'll need a small pitch prop like a 19 aluminum or something thereabouts. Just watch the top rpm. For top end use a 22 or 24 small blade chopper or even a Yamaha drag prop of the same pitch if you can find one. Search around the net you should find one reasonable.
