Hello All,

I am in the process of repairing my brothers' US60 from a minor mishap. the plane currently has a K&B61 with a Perry pump that has a leaking diaphram. I know I can send the motor off to get another diaphram put in it, but I am considering getting an OS75 and putting it in the plane as an early christmas present. What I need is the weight of both motors including mufflers so I can determine how much lead I need to remove from the nose of the plane (assuming the OS is heaver than the K&B, which I am almost positive it is). Any help will be greatly appreciated.

Thanks
