Sorry my replies have been going to my spam folder apologies
To update i am no further ahead as the force required to shift the pump was scaring me so I bolted it back together and all is working fine I shall have another go at a later date when I have a new Johnson pump in hand as I was...
Ok thanks for that I will try the breaker bar on the front pulley with hope but this thing is stuck hard for one reason or another cheers for your input.
Hi all I am in the process of changing my raw water pump how it is stuck tight in the housing and am not sure how much force I should use to loosen it any help would be grateful cheers.
