32" hotr 90+mph

[Jeff Wohlt]

hmmmm....when Bill Seebold, Sr....thee prop master of all times, put more cup in the tops of my raker prop I saw more speed and lift. Wish I had not sold that prop with the boat...it was the last prop he did and he engraved his name in it. Got to go to his house about an hour from me and see his shop...had all the old racing mercs from 30-40 years ago.

...V9 do not work great on Cats....

Funny, I set two very long-standing NAMBA SAW records using v940s on my P and Q cat......

Howard's cat would be legal in a NAMBA SAW event, running in T Hydro or T Offshore classes. But getting 90 mph on a GPS and running two back-to-back passes for 330 feet each are two far different things. I'd like to see Howard try it - and succeed!

BTW, for those who discount GPS accuracy, consider this. I usually run a Garmin 101 in my SAW boats through the traps. The GPS speeds are almost always within 1-2 mph or less of the official timed speeds - this at 80-90 mph. What GPS inaccuracy? I believe what I see, not what someone else reads online.

You should check into someone cupping your s225 or s230, or try it yourself. That would give you the extra speed you want without the problems from the larger props.

I already ordered the prop so i will give it a try but i think your right. Wednesday i should have the new prop and we will see.

Cupping will not increase speed it just stops the hop. To increase the speed you need a higher pitch or bigger prop.

To get more pitch you will need to go to the V9 series. Since it is a three blade you may need to start smaller and work up. I forget what type of hull you are running, V9 do not work great on Cats. For a two blade prop Possibly a 1750 or a 1950 they may need to be delifted or curled/ cupped on the ends to reduce lift.

I just finished reading the whole thread.....Way to go. I'm stoked you got the number you were after. I can't wait to see more from this boat.

[Howard Lee]

Thats a lot of pitch. Im not saying it wont work but I have tried those on monos and I get less speed than the prather 1.55 pitch props. Have you tried a x648 octura yet? Its a bit more pitch than the prather, but not as much as the 1.8 ABC prop.

I havent tried one on a cat though...it could work. I think they are intended for hydros, so I guess a cat would be a lot closer fit than my mono.

Great job by the way.

At this point I dont know how you could NOT want to go for 100...

The pitch i think will be to much but this is the only thing i could find at 1.9 and bigger then 76.19, a x648 will not make much of a difference. If anyone knows a slightly bigger prop then a panther 230, just tell me.

[keithbradley]

I think i might have just found a prop. I might try a ABC 48.3mm diameter and 86.8 pitch.

I just watch the video
Man thats crazy fast

Well it's too windy there and you don't have time. Just send that boat and your genesis over to me and that R1 you have. I'll put them all to good use for you Howard. Lol

Maybe just for a weekend lol

I ordered a new prop so let what happens with it. I tried a panther 235 for 4 runs but the boat didn't handle right, so i put on a 230. With the 230 i got 90.5 but after making 4 runs with the 235. I wish i had more time to test but its windy everyday, its that time of the year.

Interesting. But your running a single drive and I can see that being a little more critical. But mine will be twin with counter rotation props. Force will be applied equally from the back if the sponsons. The drives do go - & + angles vertical. But if one wanted a horizontal angle could be achieved by shimming the stinger where it mounts to the hull.
I'm always open to learning and understanding new stuff tho. :)

With my single drive i don't have any problems with the boat pulling to 1 side. I just point and shoot. Maybe your right with stingers, i just prefer a strut. I will tell you the best angle for your 37 another time.

Outrunner or inrunner? Suppo has some outrunners with some outrageous specs. Dont know if I believe them. But if they were true whoa boy.

For me inrunner is my choice. I was looking at your thread, nice setup. The only thing I'm not sure about is stingers, there is no prop angle adjustment, only a fixed prop angle with a up or down adjustment. For me I need this adjustment. When your cog and prop angle match you can really push the limits.
