Re: IMCO Dual Ram steering problem
 

Sometimes you have to drill 'em, sometimes you don't. Length of boat (lenght of hose), strength of pump, etc. A lot of variables. Sometimes they tell you to run a smaller pulley to get the volume up, sometimes you have to run a separate reservoir. It all depends on the application. Dave, sounds like you nailed yours the first time.

Where please is this ORIFICE NUT on the PS pump or on the merc steering valve?

It's on the power steering pump, the big nut that the tube runs into.

Thank you for your quick reply. I'll have a look...

I mounted a external ram and cannot turn the steering wheel anymore. We went back to the original merc system and the same issue occured... so we are f...ed! :( But I'll let you know...

He there,

I did the ps pump doctor today!! We went back from external steering to original merc but steering wheel was almost not moving. Then we drilled a bigger orifice hole into the nut on the hydraulic pump - same sh...!

After all we took the complet steering cable out from the helm to the merc cylinder and saw that it was bent inside the aluminum pipe where the cable will be fixed to the tiller arm.

This pipe broke right away apart next to the big adjustment nut on the left. So we tried to reweld it but the nut was steel and the pipe is done in aluminium!! F...ed again!

When taking the cable apart from the helm we saw it is also pretty much of play in between the gears. So we decided to go definitely to full hydraulic and draw all this original merc stuff away...

Thanks for your help!

End of the story. Cheers!
