Gary pulled the engine and had it dyno'd and it made around 400HP at 5000rpm. Then he had the engine worked over, ported heads, roller cam, new intake, carb, ignition, exhaust, and... After some $5000 in mods, back on the dyno; she made 498HP at 5600rpm. He said with the same 3 blade prop she ran 81-82mph GPS at 5600rpm. Cracking the 80mph mark was confirmed by the next owner of the boat here on OSO as well... :D . |

There are two marina's in Chester that let you store on your trailer and use their ramp. That is what I do... |

JAYHAWK: Not to pick: GPS accuracy: GPS is nice and precise until you get down to scales under 50'. GPS time and frequency reference tool.How do you calibrate a barometer in my GPS? What you are actually calibrating when you want to view the correct elevation or normalized/barometric pressure is the alitmeter,The barometer is simply a sensor that determines the ambient air pressure, or the pressure around you. Once a pressure reading has been obtained, you can calibrate the GPS altimeter based on either a known elevation or the barometric/normalized pressure. "GPS GARMIN ETREX HAND HELD"
Please read this in detail: Takes 1 hour to dial in for an aprox: average and accuracy of a GPS fluxuates and is not exact. One GPS can be off mult MPH from another unit. http://gpsinformation.net/main/etrexsum.htm |
Re: 24 with 525 or 600
Super Air, My etrex doesn't need to be calibrated. As is states in the link you postede. The etrex " SUMMIT" is the model that needs calibration. I've used my unit many many times against other GPS's. In dash units and hand helds. All were the same reading as mine.

Re: 24 with 525 or 600
The point is GPS is not precise - anyone that understands how it was designed and what they want the public to use it for can realise. GPS can and sometimes are diffrent from unit to unit. Speeds, marking etc.

Re: 24 with 525 or 600
The step bottom should run mid 80s with a 525 and low 90s with a 600 right?

Re: 24 with 525 or 600
Johnny, the #s between the 525 and the 600 should be about 3-4 mphs at best.
