Sup guys. Just rerigged my 21 superboat with a 2005 225 optimax. Im very underwhelmed with the performance on it compared to the old 200 2.4l. It has a 23 pitch tempest prop and a stock setup all around. Its only getting about 5k rpm wot and only hitting low 50's. I love how well the engine runs but I need more performance. Would love some input on where to start to improve performance. First off, prop? Lower unit?
