How difficult is it to change a water pump on a 1984 Yamaha Pro-V 150 motor?

It has not been done in about 5 years. Is there anywhere that I can find instructions on how to change it?

most any v4-v6 manual. the procedure stayed the same until 95. the 95 up procedure can be used if you disregard the lock coller steps cause pre 95 dont have it. some place in this forum I posted a step by step bolt by bolt method of water pump replacement. if your problem is low pressure at idle check the pressure valve and replace the grommet.<br /> play with the forum search and see if you can find it
