Hello Just bought 30 proline twin 225. Has not been used in quite some time. I drain tanks new fuel,the previous owner removed the oil injection system ( He said that it could fail and to pre-mix is better) so i did. 50 to 1 penzzoil. Does anyone have a suggestion on other maint. i can do? Can i use factory fuel filters (gas) with pre-mixed fuel? He said he had changed lower unit oil and has not even used it.Any idea's ? Thanks
