I finally got my engine squared away and the boat is running smooth. I have a witchcraft hull 18ft, and an olds 455. A Jacuzzi WJ with an energizer and A impeller. I get it up to 5100 rpm and GPS a speed of 62mph. I am thinking a droop is the next best thing to do???? I also seem to get some slight cavitation at speed in the light choppy water and tach will maintain 5200 rpm (loader... inducer???)
Any ideas?? Thanks!
