I know there is going to be nonbelievers out there.....but yes it was on GPS TZ .18 Y535 (PROP DEPTH .812) From bottom of hull the center of prop 30% fuel

hit a top speed of 46.7 ran mid 40s all day and witness to ..... have pictures but the server here at rc is having problems...will down load them as soon as possiable

I will be the last one to tell you thats not possible with a .18, I'v done it and then some (but with a bigger prop),, I will say it's a little on the high side for a Y535prop, that TZ had to be SCREAMING with that small a prop.
Where did you have the GPS Mounted???

Wish you were taking Vids and Not Pics of it,,,LOL,, I always love to see a fast .18 Hydro vid[8D].

I believe!
I believe!
LOL

I believe also.

Dan.

I also believe it. My vegas was in the mid to upper 40's with a CVR and the same Y535 prop. (I never had it on GPS, but a guy we run with had GPS in his tunnel hull, at 43 mph and I walked right around him with ease) It just didnt have anymore with that prop, and I hadnt had time to test others. Then lost radio communication and now she is toast Oh well, fun fun fun little boat while it lasted.

A properly setup MVD should go that fast.....so I believe you as well. Just got done breaking in my SV 27 with an engine similar to yours. I am going tovisit a relative this weekendwho also has a MVD but all stock...and I am his mechanic/goto/trainer for his boat. It is all stock, but when I get done setting his up, then we will weigh options to go faster using thisthread as a reference for possiblities........like Amax said....vids would be nice........

I've had a lot better results with a X437\3 or a M440 or Zippkits 440. But not with a TZ Personally but know a few that are running the TZ and spining the 437\3 prop.

53 for me in my setup.......but turned it down some, you cant possibly race a vegas at that speed, on the edge with 5 other boats in 10 mph winds...gps runs are good for testing and mak speed, but ACTUAL racing is a different story.....My opinion.... when I lost my gps...i never looked for another one....its not something that I use anymore as a tunning tool.

I had the GPS next to the radio box this TZ runs much differnt then my friends tz,s it has always had much more rpm ...it has 3 to 5 mph more then the others boats...and everything is the same between boats, I have no answers for this

Your not getting an accurate reading on the GPS unless it has a CLEAR View of the sky, especially the LOGO as most GPS manufacturers put the Antenna under the LOGO.

I have never clocked the speed on my Vegas but it does scoot along pretty good and I am guessing on a good day it runs high 40's in race trim, it has a mod super tigre 18 and a proboat pipe, turning an x 637 . Here is one of our district race vids. http://www.youtube.com/watch?v=3XVNAxM3Duk
