88 Spectra 188...150 blackmax with shaved heads, intake, CCMS reeds...21 pitch cleaver....68.5 at 6200....going to try a prop with a little more lift to get more of the hull out of the water...but for now....no bitches....runs like a swiss watch and I use it all the time...it sits at the dock behind my condo...I also have a 23 Powerplay I bought with a 450 horse 502 that was blown up, that is now going 548 cubes and 650 horse....that will be a fun one.
Have you ever run this boat when it was all stock? I have the same year and model, with the 150 XR4 and 22p Laser II prop, but haven't run it yet, and wondering what speeds I can expect.
Also, another member mentioned his Spectra chine walking badly at top speed. Does yours do this?
