Hey, i just got this motor and dont know anything about it. Does it take a mixture of gas and oil or straight gas. What kind of oil does it take for the motor? Thanks

50:1 oil mixture. Good grade of TC-W3 outboard oil.
Cheap oil or wrong types of oil will plug up the ring and ports in short order.

The only thing I can think of on the bottom of the outboard with a drain plug is the gear housing. Is the propshaft coming out of that tank?

Re: 1985 3.5 questions

when i looked it was dark, I am gonna check tomorrow to see if there is anything in there. From what it looks like the shaft does come out of there so i figured it had gears in it but wasnt sure.

Re: 1985 3.5 questions

That's not a tank, it just looks like part of the structure that the powerhead mounts to.

Perhaps that screw is for a flushout or to gain access for cleaning, but I would't expect you'd need to do anything with it in normal circumstances.

I have a feeling that the screw would be very difficult to get out without a lot of heat and an impact driver.

it wasnt hard to get out at all. But i saw nothing in there so i dont think anything was supposed to go in it.
