GrimRacer 40x52/3

is this prop that same as the stock sv27 prop? If so would it perform any different? I was told it would be better but it looks the same just metal?

not the same.....that's the one Grim Racer recommends and its a 3 blade

Ive got one to try out.
Ive also got a S/B x440/3 and an untouched x440/3.
I'll post up info once i get my battery situation fixed.

Well it's on and I'm tring my new sv out tommorrow. I can't wait I hope this prop is alittle better then stock cause the stock one sucks for getting on plane

[z400]

It should be a better prop.
I just dont know how it compares to a x440/3

Has it been sharpened and balanced? It should be for best results and to save bearings from wearing out fast.

Well I got to trim out the sv today. I'm not fully happy it felt slow maybe 30 mph. This is a full marine greased and I check for binds and 0 deg prop shaft angle. Also I opened up all the water fittings and rudder holes. Humm it felt faster with the stock prop. I'm surprised it wasn't faster with two 5600mah 35c 45burst 2s lipo's, also I had the cg at 8.75 from transom. Trim tabs were moved just down enough not to bounce the boat. I think I need a better prop? Is there a direct link to a web site were I can order a prop that needs no work just install and go? I'm not looking to sharpen and balance a prop if I don't have to. Any help guys?

Buy a Prather 220 and have it sharpened and balanced.

240 works well also ...........

Brad65, When my SV was stock I had the best performance from an Octura M-445. Gps at 43 mph. If you don't want to spend that much to test a prop look on the OSE site at these, Product ID: grp-2317.42, Graupner K Series 42mm and the Product ID: grp-2317.45 Graupner K Series 45mm. For the price you can test them and then purchase a metal one when you find the right one. You also mentioned greasing the flex shaft. One word of warning, do not use any kind of a silicone bassed product. One of our club menbers used one and he lost about 7 mph right away. Best grease for the boat is Grim Racer Speed Grease. If per chance you used a silicone bassed grease remove it and replace the teflon liner.

Very interesting a you guys. I like the idea of the cf 42,45,48 props on this site to try out like u said for the price how can u go wrong thanks guys. I'll get this sv27 up to speed soon. I got a friend with a nitro sv that wants to take on my brushless sv, well I need a prop first LOL

skibo2 On my bj26, I'm using blue marine grease from my grease gun that I use on the wheel bearings of my BIG BOAT but not sure if it is silicon based. I guess I'll check tomorrow. Why, too thick? I'm using air gun oil in my Traxxas Villian as it has feeders

[brad65]

Wow I'm wondering myself it the marine grease I got from walmart is slowing me down also. I read the back of it

When I first started in RC Boating I used the blue marine grease from my full size boat on my Enforcer gas boat and I noticed the speed was slow and the shaft felt sticky to turn by hand. I then cleaned the grease off and regreased it with car automotive wheel bearing grease and the shaft turned much easier. The boat picked up a lot more speed. At that time I was advised by an old timer in the sport to use the speed grease from Aquacraft and have been using it ever since. I own 9 boats, FE and Gas and use it in all of them and have never had a shaft failure. I grease the shaft after every outing. The guy in our club that used the silicone based grease was using a grease put out by Traxas for cars.
