I have a 2002 Gulfstream with twin Honda 130s with 1000 hours. I have no problems with the engines but I would like to explore my repower options. I would like to move up to twin 150s or 175s, either Honda again or Suzuki. I know there are factors that come in to the price like upgraded gauges or keeping originals. Can anyone give me a ballpark price, installed, so I have some idea when I start meeting with dealers? I'm in Ocean City MD. Thanks!
