Hi, I just bought a 17’ Jon boat fitted with a 40 HP Oil Injected Mariner motor ( 40 ELO, lE9L, SN: 430989 ). The seller told me that it ran well last season and hasn’t used it this year at all. He said that all “should” be fine ‘EXCEPT’ that he thought the key switch was broken because the electric start didn’t work and that the pull start would start it up ok….. (at 64 I can’t see myself pull starting a 40hp though).
First thing I did was to take the entire rig home for a cleaning and vacuuming. The wiring to the battery was a real cob job – I haven’t traced any of the wires yet until I know what should/shouldn’t be there in the first place. The fuel tanks were pretty cruddy with stale gas, and the oil injection unit was nothing more than a big mess.
Since I’m unsure of the nature of this beast I decided to replace any items that might cause problems….. I bought a new Marine Battery, 2 new fuel tanks and a new fuel line w/primer bulb.
Here’s where I need help from you folks:
1: What year is the motor?
2: I don’t trust the fuel injection unit, can I by-pass mixing the gas/oil at a 50:1 directly in the gas tank (as I did with my old Evinrude 40)?
3: To test the starter motor, can I use jumper cables from the new battery just to see if the unit spins?
I’ve been to the lake a few times in the last few days watching and learning the correct way and correct manners of boat launching. Towing isn’t a problem, been pulling trailers around most of my life…. I just want this to be a safe & enjoyable way to do a little, quite fishin’ without bothering anybody….. Thanks for helping.
