I have convereted a 2.5 XR6 to what Iwas told is a Pro Max 225 And I guess my question is ,What are the steps ,parts,and setup to make this thing run . This is some of the background on this engine . At first I added solid mounts ,a 200 tuner and a 200box ? that advances the timing @a certain RPM. I replaced the stock carb's with some WH 22 's and for the size of the boat that was under [a190 pro v blazer ] ItGPS speed was 73.8 MPH I blew the power head and I replaced it with a [Pro Max 225 power head and used the Wh22 carb;s . There was no change in the M P H . I then installed a Merc E F I with a Pro Max electronic box . That seemed to light it up some I GPS it @ 77 MPH @6500 RPM . This was all done in about 18 months. It will still turn 6500 RPM but the speed has went south , on a good day with the GPS I can get 66-67 MPH . I sure could use some input and discussion on this . HELP . THanks in advance. blazerboy......
