1987 Looper v4 140 RPM only 4000

[nymack66]

Boat runs like a like a champ, RPM is up to 5700 at WOT with a 13 3/4 x 15 Aluminum prop . I did not clock the speed , damm GPS was in the car !
Temp is 140 at WOT and drops to 120 at or around 2000 RPM.
Now just for the hell of it, I rescued a V20 that was slanted for the dumpster today, I brought it for the Hull only its in great condition I could not pass it up. I will have it re-panted since the previous owner painted it with a roller brush and then looks like he was rained on !! I will post pictures. Check out the craiglist listing for it . http://orlando.craigslist.org/boa/645211943.html
