That thing must be moving pretty well, touching 80? Must be pretty close.

Yeah she was moving along quit well 90 gallons of gas 3 guys first run on Torch Lake "glass" 78 on gps. With a tone of throttle response. There is definitely nothing silent about my Silent Thunder with 4 4" exhaust hole in the bottom of it LOL http://i1189.photobucket.com/albums/...ps5dde6929.jpg

I NEED to take and post pics!! Mine is SO CLOSE!! LOVE IT!!

Will those TRS's handle that RPM and HP??...I am SERIOUSLEY considering Konrads.....I see your just North of me? I run out of Holland.....got one blown TRS on my STOCK 420,s right now......who went through your TRS's??

I've had the boat now for 7 yrs and haven't had and problems spinning them over 5000+rpm i just check them every year. "Preventative Maintenance" LOL This boat has all ways had 500+HP its whole life might of hurt 1 drive sense 1986. Torch Lake Marine went through the drive this last fall. after 300 hours gears still looked great I had them shimmed and new bearings. This is the most power this boat has seem with the new Dart motors at 622hp a side. i got about $2500 into both drives.

that's a really nice boat because I seen you in it last year up there in Traverse City. I was searching for both and wish I could have bought that one last year congratulations man looks nice the new motors.
