an interesting project to make that tug go near 80. the motors are what they are cant fuss with them now, but 5600 just wont cut it. my 510s buss to 6250 and i have run them for 4 years and still run like a clock. trim the boat in 1' chop loose is fast dont get scared of it you will be safe in that sled...

I had 660-670 HP 540's with Konrads on the Mistress, best I saw was around 76-77 on GPS and that was with the drives spinning in 5400RPM.

Drives spinning out the best was 74 at 5300 RPM.

26" non labbed bravo 1's.

Throttle up said that they could have gotten me a couple of miles per hour.

The Konrads are 1.7" shorter then the TRS's but many of the mistresses had a super consertvative X dimension. It all depends on your original setup.

Good luck, you won't be the fastest , but it will eat water.

Just want to Thank everyone for their helpful advice. I ran the boat last weekend in some pretty flat water. She climbed to 5600rpm's and ran 73on the gps. I feel I still had little more speed in her. I could have raised the drives another notch. Boat handled and ran Great!! Thanks again for all the advice given on this board.

Sounds like you got it adjusted, with time you will find the sweet spot. More speed will be had with chop to put a little air in between the running surface and the water. Enjoy the boat and the new setup!
