Post 25 GTR Prop Choice?
Changed my plans on getting the Mud Buddy HDR. Picked up a frame from a ’13 35 Vanguard GTR – and am going to mount my 25 Robin on it. GatorTail confirmed it will bolt up with the addition of a “bar” bracket, which I ordered for $44.00. They also said the gearing was the same on both models. The prop is the only other thing I need to change.

That being said, I’m told the prop I’ll be getting is as 11.5’’ 10.5P. What do you guys recommend on prop? Its going on a 16.5 x 48 Uncle J that is going to be pretty heavy. Rigged hull with no people will probably come in around 675.

I've always run the stock prop on my 25. The only mods to props I have heard about was the refuge props require a little more cup. I think the normal 25 props are the same as the 35's but 1/2" or 1" trimmed off the diameter to make it 11.5" total. At least that's all that looks modified on mine.

GatorTail said the 35 prop wouldn't work on the 25. I didn't ask what their 25 prop was though - thought I might get a little better feedback on here.

The best prop is the one it comes with. You can get a second hand big blade or hammer and have Jay tweak it. I was running a modded hammer on mine before I sold it. Got pretty much the same performance but didn't wear like the powertech.

Tweak wasn't the right word, he did a lot more than tweak it lol

When I bought my 25gtr I ordered it with 2 props, with the intent to have one modified into a refuge legal prop. When I got home I realized one prop was unpolished and 12" diameter, and one had been polished only around the outside edge and measured 11.5". I use the 11.5" and had the 12 cut to a refuge 9". I'm with you though on the idea that there may be a better or more efficient prop design.

I gave it to Jay when I sold the boat since he did all the magic and I was going with a big block

I can attest to Jay's prop work! Took my barge of a boat up 2-3mph with prop work alone!
