External Oil Tank

[jhafner]

Hi Everyone,<br /><br />I am a fairly new boater and when I winterized by boat last year, I didnt drain the external oil tank. Is this critical? I know I should probably drain and refill the tank with fresh oil. By the way, the motor is a 2000 Johnny 115 HP. If I refill the tank, do I need to purge the oil line? Also, what is the best way to drain the tank? Thanks very much.

If there is no condensation just leave it alone, jhafner.<br /><br />It doesn't age or spoil.

It does pose a problem if there happens to be moisture in the tank. That creates a problem with the VRO pump. Remove the tank, drain it, clean the filter and then refill it. Purge the line and you are good to go.

Re: External Oil Tank

in spring: check filter in bottom of tank<br />replace if needed<br />if oil is suspect drain and refill (use a good QUALITY tcw3 oil) suggest johnson\evinrude xd-30 or better<br />run a tank of mixed gas thur motor to verify oil consumption then your good to go<br />do this service at least once per year and run a tank of mix after motor sits for long periods of time<br />this should be in owners manual if you don't have one order one from a dealer service manual may also be a wise investment
