I repaired the waterpump of my 2000 Jonson 30 HP.<br />Result:<br />The waterpump is ok, but the gear box is leaking<br />because of a leak of the inner input shaft seal.<br />The cause for it is the seal position had changed just a little bit because of the removal of the lower unit.<br />Since the shaft is worn out through the seal lip in the short time since purchase it became leaking.<br />It won't be easy now to get it sealed again.<br />Crankshafts of cars will do it so much longer.
