Hello everyone. I recently purchased a Mariah Z212 with 5.7 TBI, May family and I absolutely love it. What’s the best recipe for more speed? It has a quicksilver 21P prop and Alpha gen 2, I’ve hit 51 GPS with two light passengers aboard on very hot Arizona summer days. My RPM’s seem a bit low at about 3900.
