Re: RE: Re: is it ok to use aviation spark plugs O-540

There are quite a few threads on here about 0-540 plugs. Do some looking. I run Champion D16 but any brand in that heat range will work. If you are running the right automotive plug, you should get 25+ hours on them unless you idle around a lot in whick case you may foul a few. Could you get more h...

Re: RE: Re: Lycoming 4 cyl cruising rpm

What I'm trying to get at is that not all 0360s are set up the same. Your mechanic will know yours best. My builder set my motor for wide-open throttle. The closer I get to 2700 the closer to perfect my mixture is. It runs rich at lower RPMs. And the oil temp won't tick till I run it 2/3 throttle f...

Sounds to me like you are trying to get advice from here to disagree with what the mechanic who works on you're motors said. Sounds like trouble to me.

Lycoming 4 cyl cruising rpm

Hi all, I was hoping someone could clue me in about appropriate cruising rpm for the boats I use. A little background, I work out of two company owned boats, one is a 14'x~6' alumitech with an o360, and the other is a 14'x8' palm beach style hull with an o320. The o360 was rebuilt about 300 hours ag...
