Do things the easy way. Use hard shafts and underwater u joints. Old school, but it works.

the grease i'm using is from texas refinery corp, in fort worth, texas 76101. phone # 817-332-1161 or 800-827-0711. it's called #880 C&C (crown & chassis), producy code #8456. not too tacky, not a lot of drag. very water resistant, i grease in the morning, don't worry about it until i'm done for the day, unless i'm testing & burning A LOT of fuel.

my jae .21 is built EXACTLY as to the plans, with all zipp supplied parts & hardware. single tube, no shaft log or stuffing box. i have had zero issues with my flex or heat.i use a synthetic industrial grease from texas petroleum. don't have the part # here. engine is level in the hull, shaft tube is bent to fit the cutouts in the parts from zipp. working great for me in a boat that just barely tops 80...........

WOW,.. please share your set up on the 80 MPH .21!!1

all i can say is i was at the pond at the campground where i practice. they also have a shooting range that is used by some law officers. a fish & game warden came down to see what the noise was. he watched for a while then asked me how fast it was. i said i thought low 70's. he said he thought it was faster, then got out a laser radar gun. he said run straight at him & away. on 6 consecutive passes, it was between 79.4 & a high of 80.7. this was in near perfect water, slight wind ripple, NOT race conditions, but in race trim. i'm running a cmb LS evo 2 prepped by jimmy johnson/rcracer158 on here. ab billet ST pipe at just under 7 7/16" pulling a 1450 (48.5 mm with 3.75 cup) also prepped by jimmy. burning wildcat 65%. it will still come all the way of the pipe & plane & get back up in about 100'. i'll have it at the fall nats h34r: .
