The Checkmate section has been dormant for a while so I thought I'd wake it back up with my side project. The boat is a 1990 Checkmate Starflite with a Mercury Pro XB250. I just had the motor rebuilt with new rings, the #6 hole bored .15 over. With 11.5" of setback and the propshaft dead even with the keel I'm running 78mph @ 5800rpm turning a Mercury Trophy Plus 27 @ 5800 rpm. I'm going to raise the motor on the jackplate, swap out the helm for a SeaStar Pro 2.0 helm and try a Sportmaster gear case. With some prop changes I should be able to get the boat to run mid 80's!
