LIke this. That happened the fist day out after getting mine back from being labbed. I now have the 1.5" shafts but that prop is at the bottom of the lake. And yes it was a 32p bravo

Dude, I would have been in the bottom of that lake fishing it out!!

you should get between 650 to 700 out of your 509. with the right builder. go with dart or heads, intake,or brodex plus custom 1050 carb, hyd roller cam 620 lift or more 112 or 114, port heads rect and get a oval intake and have it ported to rect. DEAN GELLNER Mr horsepower on here gets 700 doing these steps plus more. he built my 572 and I have the some of the parts to get my 650hp 509 to 700 from him.but it only has a few hours on it, pm me with any Qs

all about set up, there was a 525 ol did 81 gps, all he did was install the 3'' raised imco box ran a 28b1 at 5200. then they put a merc 600 plus a 1'' shortie with the box got 87 at 1st testing. these boats need a x of 17 to 18'' or prop height between 5 1/2'' and 4''. you get better handling and speed. my baja is much better at 5 1/2'' then stock. so far my saber 28 likes the 3'' and 4'' heights with the box, now its working on cg.psI ran out of prop testing my 24ol with 650hp and 83gps at 6000rpm. need a bigger prop to get the rpms down to 5600 to 5800= more speed.

I read about his results and I've spent alot of $$ trying to replicate it with no luck. There are a few out there that have had some success but most will never see 80 with under 650 HP.

That is a rocket! Way cool! Be safe...
