The 26 will give you good baseline data, but may not be the right prop. When my HTM was about 850 HP I used a 28 and a 30 depending how much weight I was running in the boat. If most of your HTM experience is with the 496, it's a whole new animal once its got enough power to make the hull work correctly. And once you have enough power, subtle prop changes drastically change how the boat handles. More than likely a prop "labbed" for your hull and power is your best bet and either of reputable prop guys on here can get you set up.

What speed do you see with 850 HP ?
Greg from Cuting Edge made a 5 blade 27 P prop for my buddy,s Sonic here in Europe that work very good ,I was planning to let him make me a correct prop after I have a baseline ,and tried some more props to provide him info .

My boat came with HTM's blown 565 engine that they claim made 850 HP, and when it was brand new it was in Hot Boat magazine and it went 114 mph on radar driven by Greg Shoemaker (who I just had re assemble and dyno my new set up) but he said that was on race gas and he didn't know how much boost. I ran the same engine with 9 lbs of boost and race fuel I went about 116 or 117 mph. With my new set up I'm running faster than that on just 6lbs and pump gas.

Greg made my current props and I'm very happy. It also works out very well that his shop is 10 min from my house so it's easy to pick up and drop off props.

Are you running a 1,36:1 ratio ? and what drive are you using ?
Mine HTM is a 1998 ,and I had to take the complete floor out because it was pretty badly rotten away ,now its all dry and fresh wood covered with 3 layers glass.
Is yours a Virage build ?
I can send you a pic of mine if you send me your email ,cause I cant post pics in this section ..

Mine is a 2002 HTM build with fiberglass floors, I got it 2 years ago and it only had 107 hours on it and had only been used in fresh water in California and Arizona and was always stored inside. So it was in really good condition. It has a modified XR drive with a 1.36 ratio, I'm currently looking for a new drive that can handle my current power.

i have a 2001 ss24 with an imco sc upper and lower and 1.5 gears. i have the original 565 naturaly asperated and the boat runs 97-98gps consistently turning a 30p bravo 1 labbed at 5600-5650 rpm's im guessing motor makes 650-675hp

racinjason65

That's just about exactly what you should be running. In 2001 Ken Lane was still building all the in house HTM motors and the single carb 565 made 650 Hp. One of my friends has the same motor in a SR24 (which is 6' longer and 4" wider than a SS24) and runs 88-90 mph. With a custom prop you should be able to break 100 mph

Thank's for all the responses i am going to try 3 different props I just bought a 24p Bravo 1 4 blade. I have a Labed 26 and for giggles i have a 22 what kinda of rps should i try to get????? The 6al box has a 6000 chip in it... I am guessing 5950 what do you all think? Does anyone out there have a wiring diagram for an HTM SR24. I got to looking @ the wiring in this boat and its a spaghetti mess I am thinking of calling EZ-ACDC but I don't think they do HP Boats. My Personal email is [email protected]. My fax # is 740 859-3027 for any wiring diagrams... Sorry i been away I was installing my new 5in CMI headers I got out in Havasue last time i was out there... I cried when i had to open up the Wholes in my transom to 5 inches and got a whopping blister on my hand from a 1/2 in drill cutting through the hall. Ouch

I have a 468 CI BB Chevy not a 496 It does have the B&M mega blower And the chiller. I am not sure of the boats history I bought it from a guy in Cleveland OH... Hank was his name. He bought it from some Punk DJ dude in Erie PA who I think hacked up the wiring. He said he was only interested in getting tunes in the boat so he could get out on Lake Erie and get Girls..... Sad to purchase a beautiful boat then Jerry rig it for some stinky Lil split tail then not care of the ramifications later. He ( Erie Boy ) Supposedly had the motor built somewhere but cant remember or just flat out wouldn't tell me but he said the motor was built to withstand 10000 RPM's but the 6al box is chipped @ 6000... So for not knowing truly what i have I am going to take my tine and make the boat better than original All the right color Wiring and some added touches here and there... I am already in touch with all the HP Boat accessory places Dana/Eddie few others. Plus some good ole fashion learning. I will get it right sooner or later and eventually have 1000-1350 HP motor in this boat. the drive will hold it so they say...Its a B-Max poker addition by the way... Those guys @ the new B-max Shop in Cheese Ville USA Wisconsin aren't verry personable and very Pricy and Snobby so when i blow up this b-max i will probably switch over to a different drive but so far the b-max is holding up. my Goal is 125mph but we shall see. I may have to blueprint the hall myself that will be an interesting crash course since i will have to learn to do it myself. Only because i am soooooo tired of BS from people who say they know but really don't and want to charge alot of money to learn on your boat. Not Kewl..... Kinda like going to a whore house. 25,000 for 6seconds of aah but its all GOOD!!!!!!!!

Funny cuz the e-mails between hank and Erie boy state that the engine is putting 750 HP... I dought that. I have an extra smaller pulley but i wont try it till i get my racing gas. there is no #s on either pulley since i don't know what size they are and how they are suppose to perform i could measure them if that would help.
