I had a 86 Wellcraft Nova with bbc, headwork, hirise, 810 holley, CMI's through a original alpha (1:32 stock ratio) spinning a 23 hydromotive 3 blade at 5200 rpm all day long with no fast start blast and drive held up for over 150 hrs & 18 years...very happy til the day I sold...always used syn gear oil...vessel was plenty fast for me
