yamaha pump gasket question

[cattledog]

installing two new impellors on superjet, and b1 when i took off pump i noticed that the gasket around pump that fits on to shoe is a bit flatened on certain spots, should i replace them they are the same on both pumps. the superjet pump has been taken off before, but the b1 never but both look flatened, should i get new ones

IMO, they are cheap, but if you feel like pinching pennies, 5200 it on there...lol
