I have a stock (recently new) oem merc damper plate. Its the triangle shape one (3 bolts I think). Do I need to be concerned with it being able to handle a power upgrade? I will be adding at least 100hp/tq to the 330hp it was intended for and wonder if its strong enough.
This build is killing my wallet and hoping I might be ok. Also im running a Bravo 3 so maybe its a good weak link in the chain to save the drive?
Any advise here is appreciated. Oh and if I need to upgrade the damper will I need a different bell housing too? Right now what I have is the 330hp bravo stuff.

i would update to a hp500 coupler,your bell housing is good,same as a 500.
