Props for my 25
#1
So far I have had pretty good results with the Bravo 1 26" four blade. Im going to purchase a new one and have my old sent out to be Lab Finished. Is there any other props I should try before I purchase another.

Chris,
I had single hp 500 carb with no mods. I did however have an extention box on it. I was told from the guy that I bought it from(Not Active Thunder) that it would do 80mph. My best was 78 mph with two people and 1/4 tank of gas. I will look around for my info that I had. I would talk to Mike (gordo) Gordon of one vision. He helped me a lot and he is getting over 81 mph on a 25 with stock 500 efi and no boxes. I am sure he tried a lpt of the props out there. I will post as soon as I find out my info,

Chris,Sorry I haven't responded sooner, but it's been a ***** of a week.
I own a 1999 25' Thunder that is a somewhat light layup and fairly high X dimension. I ran over 81 in the Shooters Shootout with a lab finished bravo 4 blade. I can run close to the same speed with a 26" Hydromotive Q IV. I wish I had played with the hydromotive props a little more because the boat seemed to handle better with the Hydromotive. I tried a 27" Mirage 3 blade and the boat hated it. On the other hand, I tried a labbed/cutdown 29" 3 blade Mirage+ that performed really well, but lacked acceleration coming out of the turns. I also had more prop torque with the Mirage 3 blades as opposed to the 4 blade props.Bottom line is, I know just enough about propeller technology to be dangerous. I have tried lots of props, but the Bravo 4 blade props seems to work best on the 25 Thunder. I would suggust you send your favorite prop to a place in Wisconson (I can't find the name, but I'll get it) to have lab finished. As good as Mercury, but a little less money.

Thanks for the info.
Gordo if you could get me the info on where to send it that would be great.
Dan, did you buy Pete Smiths boat.
I need to get mine really dialed in this year. Ive had some mild engine work (s/b pushing 525hp) and cant get it outta the low to mid 70's.
A little disapionting for the power it has but it is an awsome boat. Ill stay in touch and have lots of questions in the next couple of months.

I have a '99 25ft. Tantrum with a 502 MAG/Bravo1. Gil wet exhaust, K&N air filter, Rapidfire plugs are the only mods to the engine. The prop was a 26p Bravo One sent it out to Murphy's in Norfolk, Va. Had them tweak it to a 25p and balance it. Boat runs 71 MPH on GPS. Sent the prop back to Murphy's to have it Blueprinted and balanced for this year. They do nice work for a good price. I tryed a 25 3 blade on the boat and it took forever too get on plane, plus it lost 5 MPH. Tried a 4 blade Mach prop got good RPM but lost speed and cavitated alot. The boat has a full interior/cabin, weighs about 3975lbs. The X dimension is aggresive. Good luck!
