I recently purchased a 2001 bayliner Capri 2150 with a 5.0L mercruiser and alpha one combo. I've taken it out twice and it runs great! I just did an oil change and I am tuning it up this evening before the weekend however I'm thinking the 14.5 X 19P prop that is on it could be limiting performance. I will mostly be using my boat in a river setting and I'm looking for just a bit more speed. Loaded with 7 people it pulls 38mph at 5000rpm. Thoughts? (I know the passenger load is a burden and is limiting speed.)
