Prop and Engine Performance

[THEFERMANATOR]

The speed numbers do sound a tad low for a 150 OPTIMAX as that is a strong 150. Then again though I don't think the MIRAGE is an ideal prop for speed on a V-20. It is a very efficient prop with alot of bite to it which is good for offshore, but that large diamtere can actually cost you up high. I know my HYDRA lost a tad on the top end with my MIRAGE copy, but it gained alot at cruising. I would say a REV4 or ENERTIA would be a better match. Also from looking at your videos I would say don't be afraid to trim it up some more for top speed. You were running pretty flat in them and it looked like your engine was at a neutral to negative trim in them when you ran it up. For max speed you want to get the engine as high as you can without the engine cavitating or the bow blowing over. Check your engine height first as that can change alot of variables right there. If you are going to be doing alot of slow speed's and cruising offshore I would keep the MIRAGE, but otherwise I would reccomend a REV4 or ENERTIA to try.
