ok, now im gonna attack the water pump. after my last session i replaced everything except for the water pump and on my last trip out my 63 merc 1000 started smoking and shut down.I have since spun the flywheel to make sure things are still moving and they are. <br /><br />Question 1: To gain access to the water pump, there is no reason that i would need to remove the power head again is there?<br /><br />Question 2: To do a compression test should I wait until the impeller is replaced to check compression?<br /><br />Question 3: For a compression test does the motor need to be running or could i turn the flywheel by hand to do it?<br /><br />Question 4: Other than internal problems such as compression, could overheating affect any other things such as electrical or ignition that I have already done?<br /><br />Thanks and any other lower unit or gear housing advise would be greatly appreciated. Im dreading doing this but i think this will be the last main change out befor she runs great. Thanks ya'll - Dunc
