Newbe question?

[ReelRaider]

I recently purchased a 14' boat with a 1993 Mercury 50HP (thanks to the respond from this board - posted the serial no. to find out what I had). Bought the impeller kit and replaced the old one ( looked to be good but why chance it). The service manual I bought tells me to run the highest octane gas available. No problem with that, I just don't know if I needed to mix oil 50-1 with the gas. The manual kind of reads the oil injection system handles the mixture. Help -Is that true - do I just put gas in the tank without mixing old?<br /><br />Thanks - Al

Re: Newbe question?

Greetings, Al<br />Welcome to the forum. It's an oil injection<br />system,so just make sure the oil tank never runs close to being dry....Instant disaster if it does.<br />Many folks (me included) do not trust oil injected systems, and prefer to disconnect the oiler system,and mix our own fuel/oil,thus making cetain it is proper.<br />But, just keep an eye on that oil tank allways,and you should be fine.

Re: Newbe question?

I am pretty sure your mercury will be equipped with an alarm. It will trip if the oil injection system stops working so, shut the motor down and investigate the alarm. I agree w/12Footer and I really don't trust the oil injection systen either systems. A good suggestion is to carry a pint/quart of TCW3 oil aboard just incase the system fails you can add iol directly to the gas.<br /><br />Bob
