What is this "notch"? Is it a step?

1999 283 Convicer, 565" Imco stand off box, 27" labbed prop, all the junk out of the front, light on fuel, very light. 87.7mph GPS, with 5 bad cam lobes. One pass, didnt see the tach or have the datalogger running. Found myself in shallow water and had to back out of it. I suspect I was at 6300rpm, but dont know.
Was going to do some backup runs the next weekend and found the damaged lifters and cam lobes. |

Thats hard to belive with 5 bad cam lobes. That engine must have 1000 hp do do that with 5 bad lobes. I don't even see how you could keep it running with all that spitting and poping from 5 bad cam lobes. :eek:

Looking at the data logs I find that I am using about 395 lbs of fuel per hour at WOT. Depending on BSHP that figures out at about 700+hp. And a couple of the lobes were worn by .015" over the nose, if I remember correctly. No poping or spitting.. ran nice. Just some rattling noise at idle.. :(
I just wish I had not run over a stinkin weed bed that I didnt know was there. The lake was full of blow boats at the time. I should have realized why they were not in that area. I had only bumped the trim one time.. I really think it would have gone faster... but nobody was with me. Just the GPS tell tale, so I can prove nothing!! Just my word and the GPS that it did.. |
ok not as big as u guys a little toy i got at a good price.......89, 20' with a evinrude 200...i know dont bust me to hard....full tank of fuel (30 gals) 4 people each at approx 150-170 no jack plate or anything with a 22pitch 3 blade raker i hit 60 on lake george in middle of october...any ideas on how i can get more speed with out slapping a jack plate on the back?

Use to have a 1996 Convincor 242 with a blown 540. Fastest it ever ran was at a radar run in Richmond, VA in 2002. With 15lbs of boost and 150hp NOS kit it ran 110.3 mph. Pics below is of the motor after it came out of the 242 and went into my cat. Sold the boat to some dude from OH in 2003. Bow-tie block, 9:1 JEs, custom Crane cam, AFR heads, Crower SS roller rockers, Whipple Inner-cooler, TBS 10-71, Nickerson carbs, and a whole lotta KE parts...
