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 !!

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

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
