just ran my boat for the first time witha abc 1814 prop, boat ran 33mph and motor was at 100* and controller was at 110*. the prop came off and ended my test run. the motor is a castle 1515 1Y 2200kv and using 4s, was looking for some octura prop recommendations. boat was not trimmed good, was not running smooth and looked wet. is there a good way to keep my bullet prop nut from coming loose again?

I'm running a Leopard 4074 2200kv on 4s. Boat runs great with an M445 prop. Everything in 100 degree or below range usually.

+1 on the m445. Will give great speed with good temps.

M445 is good.i would probably try something with more lift given its a hydro

Use some loctight on the shaft. Just a drop. You're gonna pick up about 20 mph with that prop if you're setup is ok.

Use these to hold the props on. Just noticed you asked about this also in 1st post also.

ya I added that in there, I have not lost a prop on my other boat but it is small 2s rigger. the hydro setup is freaking insane compared to the rigger. I am going to make an order from OSE in the morning, Thanks for all the info.

Yup my knees still shake everytime I run my Stealth. Scares the heck out of me too, but I love it! Hydros are addicting. My son has been running cats, v's, and tunnels. He's been watching us run ours and picked up his own recently. Now he's a hydro fan too.

Mine ran well on an M445 and an X642 with the 1515. I'd suggest running (2) 4S packs in parallel if you are not already doing so, otherwise you may puff the batts. You should easily be in the 60mph+ range.

Where is your CG?

I always ran a m445 on the PT stealth I bought from rummy, tried a few different including the x642 but overall the m445 was my fav... I had a 4074 2200kv... so same basic setup.... ran great... just over 50 and handled like a dream...

I am running to 4s packs and my COG is 15.5". I have a x640 on order should be here Wednesday. I will do some test runs and tuning with the m445 and see how fast I can get it going.

Mine too when I run the 47" Mono in my signature below, and this is a fact, not just a "saying"...............folks wont know until they have seen 20+ lbs of fiberglass and aluminum fly by them at 70+ mph....................way different deal than an Impulse at 45.

It is a "rush" driving some of these boats. I've been told I "shake like a crack addict in rehab" after running. Plus it's alot safer when your life is not actually at risk.....well unless your wife finds out how many boats you have or how much they cost. lol

If my wife knew I had a grand in my 47 incher she would not be happy

well I just ran the boat with a m445 and it is hauling butt. the gps only read 28 but it is not getting good recep. inside the hull. I raised the strut from 7/8 to 3/4 and put a little angle to raise the bow. it was flying. i am going to try another run with the gps on the outside.

It sounds like your GPS is reading wrong. You should be running 50mph+ with that prop and setup.

well i ran the boat again and the gps said 43, all i know is this thing is flying. when I turn the boat the speedrops way down so I will have to do some research and see why.

well I ran the boat with a x640 and my speed was down, no change in set up from m445. so for now I will stay with the m445 until I can find some one to run with that has some knowledge to tell me if I need to do some set up changes. my temps are about 110 after 5 min.

Give the ABC H-5 prop a try. It's 6mph faster than the M445 on my hydro (33" Whiplash) so it could be similar on your PT. That was with an 8XL 2075 kv motor. But I also run it on a TP Power 2200kv motor in it too. It has a bit more lift than the M445 so you might need to raise the strut a smidge.

that prop has a bit more pitch than m445, what were your temps w/ the h-5

I seldom check the temps after a race anymore except with my finger as the setup is so predictable with either motor.
I think the temp was around 50c on the 8Xl & 48c with the TP Power motor when I did do it some time ago.

well the boat has been with the painter for a few weeks, I can't wait till its done so i can get back to testing.

I would try a M545 if temps were good with the M445.

well i ran the boat at at club test and tune day a couple weeks ago. I had a x448 and boat ran great the guys at the pond were impressed for me being a first time boater. the gps said 52.2mph and was averaging over 220amps and temps were at 150* after 5 laps. someone helped me out and let me try a m445 back cut and and some other major cutting, 53.3 gps but flipped 210amps avg. but temps way down to 120*
