Timeserts work OK but IMHO a Helicoil makes a better overall repair and are a little stronger as far as bolt torque and longevity. I have used both and as far as time to do the repair is concerned, Timeserts win hands down, but they require a lager area to perform the same repair than the Helicoil which is why I call them a little stronger.....
Just my opinion...No need to get excited yall'

LB, If you didn't get frustrated while working on a boat...it's too new

On our last race pump, I had to drill and tap the bowl bolt holes and install Helicoils in all of them, the problem was, it was double drilled.

There's an entire day I'll never get back.
