Guys,
I am new to the forum and I have a question about my 97 Speedster before I start to tear it apart. This is a recently purchased boat and I was told it had a problem with losing power above 4000 rpm. The hull was in great shape just needing a few small fixes to hatch catches and the plastic hinges, the interior is new, both engines run excellent and I got it complete with galvanized trailer for only $2,500 Well I dropped the boat in the water to give it a test and sure enough at about 3500 to 4000 RPM the boat began to cavitate and would not plane. I brought the boat home and have inspected all things I can see without taking things apart. The tolerances on the wear ring look very tight and closer than the recommended maximum of .040 and the impellers are in nice shape. I did notice that the white plastic tube that penetrates the underside of the hull from the engine bay surrounding the impeller shaft to be cracked on the starboard side and actually broken off almost flush with the hull on the port side. Would this part missing or being damaged cause this effect in both engines? If so, do I need to pull the entire pump assembly from the boat to replace the parts? Would you suggest replacing the wear rings anyway if I take things apart to this level? Any other suggestions would be greatly appreciated because I am dying to get this boat moving the way it should.
