Re: CHT gauges

If you look close the bottom is Centigrade and the top markings are Fahrenheit. It looks like that one goes to 600° Fahrenheit and 300° Centigrade. I hate metric and centigrade measurements.

Re: CHT gauges

One word of caution on those from Aircraft Spruce. Those are designed to be installed in a dry enclosed cockpit. They don't hold up in an outdoor envionment. I use the same one but I cover mine when the boat is parked. They will last for years as long as they don't get direct moisture. So, figure ou...

Re: oil temp on a 220 GPU

190° to 200° is perfect. 210° is no problem as long as you keep the cylinder temps below 500°. I seldom get above 180° on mine but above 180° turns moisture in the oil into steam which is good. 250° is the max oil temp, but you will probably fry your cylinders before the oil gets that hot. If someth...

Re: PROP PITCH

I will use the pitch marks for reference only, once I have my rpm close to my goal I dial it in with a tape measure and a good location on the hull or rigging to get it dialed in. Tracking a prop works well most of the time. im not doubting ya but ive never in my life heard of anyone other then tra...

Re: PROP PITCH

That's a trick question. The more pitch gives more push up to a point but too much pitch and it's a waste of efficiency. With my pitch setting I'm leaving a lot of horse power on the table. If I get stuck I won't be able to turn the engine up to get the extra torque that is available. My setting wor...

Re: PROP PITCH

JAMES, was there a question in there? I never run the motor at WOT. I seldom hit 2000 RPM except to get on plane and that is just for a few seconds. I'm not rich, so, I try to take care of the things I have. 2500 rpms is probably about right for the 3 mark pitch setting. That is just for me and not ...

Dixiedog60, I have my 13 x 7 foot Laser Hull with a 220 GPU set just a little past the 3 mark with a 72 inch Q. It jumps right up on plane and I get great cruise at 1800 rpm.

Re: 220 Oil Cooler

I agree that the 220 oil cooler is the one to use if you can find one. I tried a 20x24 inch Hayden engine cooler and it did not do as good a job as the 220 GPU cooler. Stay away from those transmission coolers and go with an engine cooler if you have to. Don't forget the oil coolers purpose is to ke...

Re: ever expierence this??

My guess is you don't have a CHT gauge and when you ran it hard the cylinders temps exceeded the maximum allowable temps. When those cylinders get too hot the fuel will ignite without the need of spark plugs. Once you cooled the cylinders down your engine was normal again. Exceeding the temps will e...

Re: 170 temp

A good rule for most aircraft cylinders is to keep the temps below 500°. The oil temp should be below 250°. The cylinder temps are more important than oil temp.

Re: 220 OIL GAUGE INSERT

It's probably not working because the probe is not in the oil. Take out one of the plugs on the side of the oil pan down lower and get some brass adapters for the probe and put it there.

From you discription is sounds like the head may be separating from the cylinder. Time to have someone look at it. You will want to check out the other cylinders too in case they over heated. Do you know what the cylinder head temp was? Could be a hole in the piston too causing the blue smoke. You r...

Re: 220 running hot?

First, never let those cylinders get over 500°. The cylinder walls will be scoured. I too have the Holley 500 and I have the oil cooler that comes with the GPU. I run 87 octane gas but AvGas will run cooler, but not 100° cooler. I have used regular Shell 40 wt automotive oil for the past 5 years. My...

Re: cont. 0-300 conversion question

No way. The O-300 uses little 3 inch pistons and the 520 uses 5 inch pistons. The O-300 is a great little 145 horse power engine but there are no upgrades to get it much over that. How much do you want for that engine?
