ok i recieved my blackjack 27ss about a week ago. i ran few tanks through it and then the first prop broke the boat did jar suddenly as if i had hit any thing, just loss of speed do missing a blade on the prop. put the factory replacement prop on do like 3 or laps and the second breaks same as the first.

any suggestions on why they keep breaking so easily or where to go to get a stronger prop, please help!!!!!!

your going to need a metal prop. but not having any experience with that boat, i'm sure someone here can tell you what size.

thanks alot but where might i be able to find a metal prop

need to get a metal prop..plastic ones breaks to easy..What motor do you have in it??If its the.15?? A 435/3 might work. if its a.18 a 437/3

it is the ss which comes with .18 and what is exactly a 437/3

Its an octura prop 437/3 is 37.6mm also these might work too.. 438 is 38.1mm 440 440/3 is 39.9mm prop.heres a prop chart that can help you out..[link]http://www.xtremercboats.com/tech/propchart.htm[/link]

another thing is there anything that i will need change on my flexshaft or out drive or anything like that thanks for the help

I'd just converted a blackjack out drive and rudder .By using the Miss Vegas setup!! Using the adjustable strut&brackets and the rudder plus the flex cable too.

i have the newest blackjack with aluminum set up already installed same as the hydro

no its not a hydro setup.. That a stinger almost like the SV27 but the SV27 has better adjustments then that setup.. Even the Miss Vegas adjustable strut has better hight setting that that has.[8D]

o i c well will be ok with the new all annodized alluminum hard ware for a metal prop

so are the Vegas&SV27 hardware for metal props too. They just put the plastic ones on for cheaper prices plus you might change your mind on what prop would work better for your boat.

not sure i got a pro boat blackjack 26 ss with the .18 motor and it has metal hardware except for the factory prop

just measure the shaft diameter, props in this size range are all for a 3/16th shaft I believe, at least I know the x 440/3 is, and it should fit your drive dog also...not sure which of those 3 is best though since I'm not familiar with cat hulls or that particular engine/drive setup

can you post a ic of the new BJ, is the hul any different ?

um you will have to give me a day or 2 dont have my camera at the house but the hull is virtually same from what i understand i have not seen the older version in person but it no longer has the .15 engine it is .18 still water cooled of course and is no longer a steerable out drive it has an offset rudder and all annodized alluminum hardware but i will post pics soon just keep checkin!!

tried to post pics my computer isnt working right right now ill do it later

blackjack 26 ss pics more to come

bj26 ss again

bj26 ss pics

couple more sorry it will only let me do two at a time

anyone have any idea what all the hardware retails for ? would it becheaper to buy an aftermarket drive system for the old bj ?

I just ordered all the SS parts for my old blackjack, its all at horizon hobby website. they have a complete parts list

those are cheap they are the ones that keep breaking
