Gauges for aircraft engine

I am having a new boat built. I want a nice set of matching gauges, including a mechanical tach, fuel, oil pressure and temp and volts. I would like a CHT if possible. Where can if find a set? I will be monitoring a 520 Cont.

Re: Pacemaker ignition system

How would you install on a Cont. 520, that is not using an aircraft flywheel? I use the aircraft started mounted on the front of the case.

Re: M 4-5 carb filter

I was told by an engine builder that these filters would choke a 540 or 520, that they would not flow enough air. Any truth to that? I really need one to keep the dirt daubers out of my carb.

Engine turning while towing

Anyone ever seen an aircraft engine turning over while towing? I was running south on I-75 between Gainesville and Ocala this morning in the hammer lane around 80mph and came up on an airboat with a straight valve 540, with a 6 blade warp drive. The prop was turning about a quarter turn at a time. I...

Re: Sensenich or warp?

Put a 2 blade 72'' NGQ on it. ( 12'' wide, wing tip) I have a 285ph 520 on a 13' rivermaster w/ poly. It is set on 2.5 and at 2850 on the trailer. Its super responsive and will go anywhere. Stays on a plane at 1700 rpm with 3 people and a cooler in deep water.

Re: 520 Contential oil temp.

Lines come in and out the top. Also I filled to cooler / lines with oil when I installed it. I did not have a problem until I reduced the oil pressure. I was told that less oil pressure would slow the oil going thru the cooler and dissipate more heat. Also, I didn't like seeing 75psi oil pressure on...

Re: 520 Contential oil temp.

The oil cooler is directly below the engine. 1st line comes out of the engine with a 90 deg fitting and straight down into the cooler. The other has a 90 deg. fitting out of the cooler, runs along the top of it, then straight up and back into the engine with a 90 deg. fitting. I would think that 45p...

520 Contential oil temp.

Some one help me with the theory of oil temp Vs. oil pressure. I turn the oil pressure down on my 520, it was over 60 psi hot while running, turned it down to 35-40. Now the oil temp jumped up, it will get near 240 if I don't stop and let it cool off. Motor only has 15 hours on it and runs fine.

Cont. 520 mechanical fuel pump

Anybody found a way to put a mechanical fuel pump on a 520? Im tired on changing electric pumps. I had another one fail today in Cedar Key. It would quit every 4-5 minutes and the motor would die. I made it in by beating on it with a pair of wire cutters until it starting pumping. The first one that...

Re: Mean little 4 cyl.

No ECO Tecs for me. I have an obnoxious 3 rotor, turbo charged Mazda I would rig up before I did that. The problem is it makes power at 13,000 rpms so I need a 5/1 gearbox. Maybe I'm to old, but the sound of the young idiots with 4 inch exhaust on 4 cylinder rice burners makes me sick to my stomach ...

Mean little 4 cyl.

If a man wanted to build a bad ass little 4 cylinder, what combination could you come up? Is it just a stock wide deck o360, or some Frankenstein Cont. with GITSO cylinders? Not a race motor, something that could be reliable.

On the last move of the day, I tried to start the motor and it back fired, its never done that before. It did eventually start b...

Re: 520 Contential Carb Questions

The engine is a new overhaul, with 6 hours on it. What are the chances that it needs to loosen up a little bit. Like I said, it starts, idles and runs fantastic.

I have been putting in at the RV park on the south shore, off of 318. It costs $3, but I am usually the only one there. I have been breaking in a new 520 and don't want to burn it up trying to get beyond the island.

Re: Oil cooler and lines

Go on the Hayden website and get the part # for the size you want, then go to Amazon and buy it. That's the cheapest I found. I then bought the fittings from NAPA, installed the cooler and measured for hoses. NAPA built the hoses as well. About $200 total.
