any preference on suspension units

Hi all, has anyone got any preference on what make of suspension unit to fit as I am considering changing the ones on my boat trailer as they are 500 kg units and think the boat with engine and fuel etc weighs more than this (going to put on weigh bridge when get chance to check)
Have had bad luck with indespension unit collapsing before for no reason.
I know I am limited on what unit to fit with mounting plates attached to trailer and am thinking that if I have to remove these I might go for Bramber Flexiride unitsas they are a sealed unit so water cannot get inside.
Any thoughts or preferences on units@

Have put trailer on weigh bridge (boat, engine, fuel and a few odds and sods that you would normally take) and it weighs in at 530kg so overweight for the 500kg units on trailer, have found knott avonride units that are rated at 550kg that will suit the mounting plates on trailer already or should I go for 750kg units to be on safe side and change the mounting plates ?, also if I go for 750 units will the ride be a tad stiff ?
Dilemma

Personally I wouldn't change them for a 50kg gain the 500 units will have a factor of safety built in anyway unless your woried about the legalities then id live with the 500kg units & keep a close eye on them for signs of fatigue
If I was going to change id definately go for the 750 units ride shouldnt be too much stiffer as you still have a substantial load on them

Have found that Indespension 750 kg units fit mounting plates on trailer, but the units are zinc plated and not galvanised, has anybody any experience of using these in salt water conditions and if so how have they lasted with corrosion issues,

Galvanising is zinc plating

I always thought zinc playing was an electroplating process where as galvanising was a hot dip process into a bath of molten zinc. But could be wrong

Different application method but same result a coating of zinc although thinner & more uniform with electroplating

Hmm! yes & no, hot dip galvanising is far superior to electroplating. Electroplating will have disappeared long before HDG has even started to show signs. They are both zinc plating, but very different systems.
