Hydraulic Helm ?'s

[CausinTrouble]

How many cc helm do they recommend for a twin ram set up?

[MattBMiller]

Check the IMCO website. They have P/N's for the Char-Lynn helms.

Thanks matt.

I bought a 230cc Helm and didnt know if it was to big.
Imco says its 1.5 turns lock 2 lock

[MattBMiller]

Mine is 3 turns lock to lock with dual rams. 1.5 might be a little sensitive

[CausinTrouble]

sounds like fun

If you know the bore of the cylinders, the stroke and the diameter of the rod,

I can walk you through the math to get the desired ratio. It's pretty simple.

I dug through my stuff but didn't have any helms. I do have an extra geroter set though.

I like a fast helm

[Griff]

I'm about 3 turns lock to lock and would prefer the 1.5. It all depends on what you like.

[CausinTrouble]

I could not pass up this deal. I didnt know the size of the helm but I knew it would work. When I got it I looked it up and its the 230cc. I guess I will have to get used to the fast steering. The boat is a 27' Excalibur and is only 6'6" wide. With 575hp it should be pretty fast and fun.

Another question: What size hose does everyone use ?

[Richard Crainium]

I used #8 (1/2")on my boats.then #6 (3/8") after the t.

[CausinTrouble]

Thanks Richard

[CausinTrouble]

How do you mount the helm under the dash....With the hoses on the top or can they be coming in the side ?

[Anchored]

You can point them any direction you would like.

Here are a few pics of my Donzi install.

You can use 3/8 on the low pressure return.

[CausinTrouble]

Thanks again guys.

After I posted, I did some more reading and figured out they can be mounted which ever way works the best for the application. When I start the install I will take pics and post the progress.

Another question.

Do the Charlynn helm use an O-ring or pipe fitting ?

[MOBILEMERCMAN]

I believe they may be o-ring, but am not sure.

Pipe would be tapered thread o ring would be none tapered.
