Re: one off belt drive

I'm in leesburg, I want to use a Honda/acura v-6 with a 2:1 ratio. I called century today and they weren't very help and said they had no interest in doing it. Didn't even throw out a number, as far a price.

Re: Where does the oil go?

Sure it can, some of the oil is obviously still trapped in the filter element, but the majority of your oil is burnt or more correctly stated consumed by your engine. You said your engine doesn't "burn" or leak oil, well all engines burn oil. We generally consider an engine to be burning oil when it...

Re: alexander spring

There is a boat ramp at the end of Forest Road 552 the will give you access half way between the bridge and the river. Last time I was there you could make it to the bridge (about 7 miles) but it would be tough to make it to the river, like tony said. It's nice out there but there's not really a who...

Re: Replacing Jugs?! PE 150

I cleaned the carbon off my pistons with a wire wheel on a grinder. If you don't bare down to hard it takes the carbon right off and won't scratch the piston at all.

Re: Our marshes and water ways shrinking.

What wording in this new bill is it that is going to change where the ordinary high water mark is defined to be. Does anyone know the florida statue number that currently defines how the OHW mark is defined?

Re: Rudder doesn't want to turn much to right under hard pow

I bet you have a bad bushing or something in your rudder mounting is lose and when you apply a lot of wind load to the rudders one or possibly both (i doubt both) are binding when you try to turn right. If you haven't already, check the rudder mounts and all your steering linkage for slop. Try to ap...

Re: Real Time Thrust Tests with Complete Boats

Great data guys!!! That is really useful information. I am very surprised to see how much the Q series dropped off with less pitch. Assuming that GITSO produces 285ish horsepower at 2750 it is a safe assumption that it is making about 300 horsepower at 3000 rpm (assuming the torque drops from 2750 r...

Oil Return Issues

Sorry if this has already been answered or discussed. I have an o-470 13a case with 520 GITSO jugs. For those not familiar the 13a is basically a dry sump design even though it has an oil pan that it came with in some applications. The oil pan is connected by a 1.25 inch opening at the front (end op...

Re: 520 Gitsu compression

Thanks alot guys, very helpful. And yes it does rotate, obviously it rotates more quickly between compression strokes and pauses for say 3 to 10 seconds on the top of a stroke but it just keeps on going round and round. Just wanted to get some opinions, I have never seen this before and new it meant...

520 Gitsu compression

Does anyone know what compression I should get out of my 520 Gitsu with standard 520 8.5 to 1 pistons? By compression I mean in terms of PSI on a compression gauge. I am not sure what pistons I have in it now but the compression seems very low, I believe its low because it doesn't seem like it makes...
