2000 Top Gun best props
 

No steps, 650hp, bravo XR with stelling standoff boxes and 30p bravo 1's on now that rotate out. It seems to have a lot of bow but I'm not sure if this is normal because I have not tried anything different. The previous owner said he ran 29p hydro as well but did not remember what one ran better. What would be the best prop? Post any experences with this type of boat.

I have had some great luck with the Hydro P5-X on the Top Guns. They will lift the stern a bit more. I think you will really like the way they feel.

What pitch should I try.

Re: 2000 Top Gun best props
 

We have propped more TG's with Bravo 1's than anything else. We have been seeing more and more people liking the Maximus and P5X though due to the cruise speed capabilities.

Re: 2000 Top Gun best props
 

What is your current speed and rpm at WOT with the 30 Bravo's you have now?

Are the 30p Bravo 1 props stock?

Re: 2000 Top Gun best props
 

76 MPH @ 5000.

Stock bravo.

You won't like 4 blade hydros on a newer non stepped Gun, maybe on an older and heavier style hull
.On our 1997 Gun we run 1.35 ratios and a pair of labbed 30 Bravo 4 blades turning out.. We also have a set of labbed 29 4 /b Hydros , the Bravos are hands down better for this boat, know comparison in ride, speed etc.
I cant say how the 5 blades compare on a Gun ,I know on our Cat the 5 blade cleavers vs our 4 blades run way better in all aspects.
Good Luck!

What power and how fast.

Re: 2000 Top Gun best props
 

Modified 600SCs 7 lbs of boost 850 hp 95MPHgps @ 5800 rpms.
Broke two Max Worx drives last season, so we de tuned her this year.

Now with less boost and smaller carburetors 5lbs of boost 750hp or so she trims up to 88 mph gps @ 53 to 5400 rpms fully loaded with fuel and passengers if it's choppy enough, in smoother water 85mph tops loaded.
Boat cruising at 4500rpms with light or zero tab and a touch of positive trim is 75mph gps with 4 blade Bravos.
You need a ton of power to make these rigs fly.
Hope this helps!

Thanks guys

Re: 2000 Top Gun best props
 

Would this be about 20% slip? What's your propshaft hight?

Re: 2000 Top Gun best props
 

Seahawk,

If your gear ratio is 1.5 then you have 17% slip and with 1.36 gears you would have 25% slip. Both are high %'s.
At what RPM is yoru peak HP produced? This may be key in your case.

I think I was still running some tab when I said "76 @ 5000" and maybe I didn't let the boat run long enough.
I just bought the boat and still getting use to it. The previous owner said it will go 80+@ 5200. I have herd that straight bottom Top Guns have an attitude that needs to be adjusted just right to make them fly. What should the slip be?

Re: 2000 Top Gun best props
 

We added 1/2'' shims to our drives to control her porpoising, thus running drives 1/2" deeper in the water and requiring a few more clicks than stock, of positive trim @ wot.
For top speed without any tab I trim our drives" slowly and gradually" to the bottom a click or two at a time, even past the #9 drive indicator until she starts to loose RPM.
If we add positive trim to quickly unless its real real rough water she will start to chine walk and leap out of the water in the high 70mph range.
Your ride with Bravo 4 blades should run in the low 80s trimmed up.

Good Luck!

Re: 2000 Top Gun best props
 

My drive indicator only go's to #8 that seems to be all the way out!!! " to the bottom" dose this mean level with the bottom of the hull then start trimming up to get the best speed?

Re: 2000 Top Gun best props
 

First thing I would do is check to make sure your indicators jive with your drive position. 0 is in against transom or lower in the water, and 8 is away from your transom.
When you plane out on your Gun you should have your drives tucked in as close to your boat as they will go or 0 on your drive indicator, with 7 or so on your tab setting to keep your bow down while planning out.
As you increase your speed keeping drives @ 0 or close to your hull until she will run without porpoising, my boat is high 50s try pulling some tab and or adding positive trim #1 to #2 tops on your drive indicator.
Until you reach high 60s low 70s you probably wont get away with more than 2 or 3 positive on your trim indicator if you want a smooth ride, which is now away from your transom coming closer to the surface or positive trim.
It's pretty much all or nothing with this hull as to really trimming her up.
At full throttle slowly loose the tabs and then start positive trim 3 4, 5 and so on, until she reaches desired rpm.If she gets squirmy go back on trim and if she wont stop add both tabs at the same time while pulling back on throttles.
This is all that's in the water when its not real rough water when trimmed up @ speed just a few feet of pad!

Thanks Wild that is the best explanation of how to work these beasts. It should be in the owners hand book. YOU THE MAN...
