hi i have a 1972 johnson 9.5 i am rebuilding. as of right now it needs a new head (on the way) a fuel pump, a complete water pump, and a head gasket and i found out today that it needs a water tube. when i pulled the head off the first time i broke the two center bolts off luckily with a little left out of the deck. i torched it because all but 3 bolts were badly corroded. i am having a hard time getting those broken two out. and i would like to get all new gaskets, rebuild the carb, and change all the bolts to stainless. and does anybody have any tips on how to keep it in good shape as i plan on using this motor in salt water. and does anybody have prices for the above mentioned parts and/or any advice about this motor.
