I have a 2006 Grady White Chase 273. I noticed a leak on the hydraulic hose fitting on one of the motors. My plan is to replace both hoses because as I researched, you can’t fix a bad fitting. It’s better just to replace the whole hose. My challenge is knowing the length of the hoses without pulling one out. Because I’m going to replace both, I’d rather attach the new hoses and pull them out at the same time l… So how do you know how long the hose is without pulling one out?

I guess I could pull one hose out and then put two new hoses in while pulling the only one left, but I’d rather pull both out at the same time while pulling new ones in if that makes sense.

Anybody have any idea of hose length from the outboard motors to the helm?

Thank you.
 
Couple of things.

You need to verify what type of hose and cylinder you have.
Probably Seastar 5/16 od 1000psi hose...but could be Seastar PRO rrated 1500 PSI for Tournament PRO cylinders.

You have to verify that you have uninterupted hoses from helm to cylinder. Sometime hoses go thru the motorwell and sometime they install fittings on the bulkhead. In thatcase you have short hoses with fittings from the bulkhead to the motor.

On 1000psi Seastar hose - You CAN replace a hose fitting using a Parker part# 2TFMS-6-5b

Measure from helm to deck to transom and then to motors. Thats your length
Premade hoses sold in pairs.

If your hose passes thru the bulkhead the hole has to be big enough for fitting to pass thru. They make strain relief plastic bushings for the hose passing thru bulkhead.

Sometimes they put brass fittings on the bulkhead and 2 long hoses and two short hoses(to motor) attach to bulkhead fitting
 
Thank you very much for the response. I do know they pass through the bulkhead. I was hoping that there was a connection at the bulkhead and I could just replace the back end of the hose, but it is one continuous hose all the way to the helm with the plastic bushings you mentioned. Unless there’s some connection in the middle of the boat that I’m unaware of - it’s a continuous hose.

How do I know the psi on my hose, will it just list it on the hose itself? Or is it on the cylinder on the outboard motor? Or possibly listed underneath the steering wheel? I do know I have a sea star system.

Last question. Let’s say I guesstimate a 14 foot run and I end up with a 16 or 18 foot hose, is it appropriate to just create a coil in the center console for the slack or does the hose length need to be pretty accurate?

Thanks again. I appreciate your help.
 
2 ft too long is better than an inch too short. You need a nice wide bend out thru the bulkhead . The excess usually lays down near the stringers.
That assumes the hoses come out the stbd side and don't come out in the center. Some models do that.

Do you have autopilot? or power assist? If so, you have more than two hoses.

Hose should be marked 5/16 od 1000 psi

Where is the leak? It IS possible to just replace the fitting.
It the hose leaking or the fitting?
 
Measure them up. Usually they only go to the rigging tubes and are metal from there to the wheel. Mine were 7' and 4' as I recall. I changed them both and they offered custom lengths at no additional cost. I'll dig up a thread.

Thread 'Field replaceable fittings for SeaStar 5/16ID hose'

Anybody here have actual experience with using Parker part# 2TFMS-6-5b as a permanent fix or to make new hoses out of old SEASTAR hoses for Seastar Outboard Hydraulic steering?
I'm talking about the 1000psi hoses not the 3/8 nylon compensation hose.
These fittings have 9/16-24 thread and an o-ring. Do they fit all the "3/8 tube " fittings? Do they stay on or are there leaks/pop-offs?

Has the same thing happen to me a few years ago. In my case the black plastic sleeve that covers the hydraulic cable right where the hose connects to the outboard chafed the line and it finally blew. Pretty scary as all steering is lost. I had time yo straighten the engines and use the binacles to get me home.

I suggest that these 4 lines be proactively swapped out every 10? Years or so. I did all mine. Pretty easy to do and addresses a single point of failure.

Fishtales mentioned the metal hydraulic lines. Some models (I thought much older than 2006 and I/Os) had metal tubing below deck.
You would probably then have short hoses in the motorwell going to bulkhead fittings.
 
Check your lines before buying. I had metal ones with fittings at the end where the plastic ones connected. I'm almost certain the size for my Marlin were 7' and 4'. Stock size was 8' and 6'. They either made em up or cut stock ones down for a OEM fit.
 
One clue to figuring out your hose length is to check the length of the control cables. The length is stamped on them approximately 18 inches from one of the ends. Should be real close to the hose length.
