Hynautic H26

i got this helm pump i have just mounted in my catamaran.

i got 40 psi on the system now and it still dont work, its hard to turn. and
the helm sounds bad ? it feels like the balls are tight
ore they are stock in some way.

if there is no oil in it sounds fine.

my helm are monted with the connections up is that ok?

i have no pressure relief valve on it but i can´t see it´s nessesery just to tjek it at home.

is the helm bad ?? has any one other got this problem with an oter helm ??

tommy

Unfortunately the only system that really works is Seastar (preferably Pro series)

You could try and find a Capilano 1275V steering pump this is a ajustible pump (also made by seastar) .
What kind of cilinder/ram are you using right now on the engine's ?

Be sure to use the correct one as the Pro helm will not work with an unbalanced Ram !! It wont make much difference wether it is a 2 or 2.4cu.

Tommy,its a lot money for a cappilano pump,the 1250 v is a little cheaper,but don,t forget its one of the most important things in your boat,you don,t want ,,good steering ,, you need the best with that horsepower and torque ,and such a light boat with high speeds, and don,t forget the people you carry with you....

I would say get a set latham or mayfair dual side mount steering ,cappilano/hydrive pump,and aeroquip hoses ,I don,t know if they made sidemount plates for a 300 hpdi,but they can be made yourself,that way you don,t steer through the steering arm and through the engine dampers/rubber mounts,but solid to the midsection where there is no flex ....

get yourself a good pump first,and watch out for buying them from ebay ,cause you never know whats the story..

Don,t get yourself a seatar unit,it is just not good enough for your purpose

I can find out for you what a new 1250 v will cost if you want ,I have good prices for those units ,let me know

sterling
