Hi,<br /><br />I have a 50 HP Tohatsu M50D motor and would like to disconnect the oil pump and go to mixing the gas & oil. What is the proper procedure? Someone thought oil might be needed in the pump at all times to prevent damaging parts.<br /><br />Also, the tilt trim jerks especially towards to top. I drained it and put transmission fluid in it, then cycled it up and down, with and without the top plug in. It was impossible to get the pump exactly vertical but almost. What can I do to correct this?<br /><br />Thanks a lot. Bob
