hynautic /Seastar hyd fluid alternative H-50 HELM replacement

[Kart113]

Greetings all my h-50 flybridge helm was developing a leak after 36 years lol . Upon teardown and inspection rust was noted on the shims and bearing so no rebuild at home possible. Seastar ( Teleflex mfg facility located 70 miles away from me in Ontario Canada ) helm hh5273-3 was needed ,best possible price in Canada was 971.00 no installation kit 1230.00 for full kit
seastar hyd fluid 52 $ cdn litre (almost a quart in US ) . Found a showroom open box helm unit ( Ebay ) for 459 US mount kit for 80 Us plug 16 Us , so even with nasty 33% exchange rate I was way ahead. Fluid flush of whole system needs about 3 quarts ,so 156.00$ cdn to pitch our most of it . Reservoir stated Aeroshell 41 Mil spec 5606 is recommended, Aircraft Spruce Canada sells for 18.36 quart 2 day delivery . Check amazon !! a little research can save major bucks.
