well dont i look stupid, thought you needed them toed in like on a car. could this cause a vibration when im near max speed?

SABER28

thanks , i appreciate it. im heading to elk /torch lake for the week. i'll try adjusting it tomorrow before i go.

Tinkerer

very much so.
You will have to play with it.
It depends on how much give you have in the bushings.
Try 1/4 inch out and I think you will be surprised at the difference.
Keep trying out 1/8 inch at a time.
You will know when you went too far.
1/4 inch is a good starting point and I think that is where I had my drives on the SCARAB.

ok, set the toe. but the vibration is possibly getting worse. is there supposed to be any play moving the prop shaft vertically?

Griff

No.........NONE

SABER28

are these bearings tapered or im guessing not since there is no end play? im guessing that this is the cause of my vibration over 80 mph?

A Bravo should have Zero propshaft play , Vertical or Horizontal . If you do .... you have drive issues.

i'm guessing about .010. lateral movement. also there is definitely a tight spot when turning to props by hand. guess im rebuilding this fall.

I should have said Axial or Radial ,,, In and Out , or Side to Side .
Man if it does I'd be checking the magnets for metal. You dont want to push your
luck and cost a bunch more money.

they are clean. the only other thing a did on someones advise was to swap drives side to side last year went i put the new engines in. or is it just time with 1k hours behind some 454 mpi's.?
