Valve/spring retainers/locks tech...
 

Okay gang, here's another interesting topic. I here of 7* retainers/locks and then I here of 10* retainers/locks and still I here of SUPER 7* retainers/locks.

My engines currently have 10* retainers/locks, but I was told that the SUPER 7* locks/retainers "grab the valve better"

Can someone tell me which is best for a marine application and why? Thanks

Good question, Ive never heard of one coming off. Maybe they are for high rpm?

I have always used 10* locks and retainers. Never had a problem with one. I have never heard of super 7*. Maybe it is something new?? As I know it, the difference between 7* and 10* is the size and diameter of the locks. 10* locks and much larger than 7* locks. It is from the difference is size that the 10* locks stay in the retainer and hold the valve better than 7*.

HEY MARK THE PROBLEM WITH STEEP ANGLE RETAINERS IS TO MUCH ANGLE AND PRESSURE CAN AND DOES AT TIMES SHEER OFF THE TOP OF THE VALVE ,,,BAD DEAL !!!!:(

DRAG MOTORS THIS IS NOT TO BAD A PROBLEM BECAUSE IT DOES NOT HAPPEN THAT MUCH ,,, BUT ENDURANCE STUFF IT WILL !!
HAVE A GOOD DAY GUYS :D :D

Bobbyd, so what are you saying the 7*, the SUPER 7* or the 10* one are what you prefer?

Mark, we use 10* with no issues yet. The more angle, the more holding power, to a point.

TO A POINT ,
I LIKE THEM ALL BETTER THAN STOCK ,BUT MY PREFERENCE IS THE LESSER ANGLE

WITH YOUR R P M AND LIFT ITS NOT A SUPER PROBLEM JUST ONE TO BE AWARE OF

I think I am asking too many questions at once
 

Okay let me ask it this way:

In reference to a retainer angles, IS there such a thing as a "Super 7*" retainer/keeper? and why does it differ from a regular 7*???????????????????????????????

MARK I'VE NEVER HEARD OF A SUPER 7 ,BUT THAT DOESN'T MEAN ITS NOT REAL ,
JUST ALWAYS BUY QUALITY AND INSPECT THEM CAREFULLY BEFORE USE .
HAVE A GREAT NIGHT
