    Supertec 4-tec GTX 185 sc valves.

    Hey guys, just looking to replace my stock valves this winter so want to start collecting all the parts I need. I noticed a lot of you guys are using the supertec valves but I've came across a set on eBay that seem quite cheap! They are the supertec valves but they are black coated instead of the nice polished looking ones. Is there any differance in these and is anyone using this set in the link bellow, and if so could you tell me if they are any good and if they are a direct replacement for the stock valves?

    Thanks jamie

    Why do you feel you have to replace your valves?

    Because the pre late run 06 have a high failure rate

    Because they are poor hollow valves that are prone to dropping

    be careful as I have seen a cheap Chinese knock off of the supertech valves. a customer purchased a set, black nitride and they were terrible. Keeper grooves were not in the same spots, heavier than the real supertech's, they might not even have been Inconel on the exhaust.

    Ok I'll make sure, I can confirm that it's the same seller that Chris ( the guy who made the "how to replace the 4-tec valves" video) on YouTube got his from. And his have been fantastic. So let's hope mine goes just as well

    I have seen dozens of these engines go 400-500 hours with no issues. SO why are they so bad? Local dealer has had a few dropped valves buy all on 2007+ engines

    Yeah mate, I know the percentage I've quite low but it's in the back of my mind now

    and when I'm out on the water just keep thinking about it and don't like to squeeze the throttle. So with that I keep thinking to myself " yeah they might not go, but if they do its a damaged engine! ).

    It Sucks like as I really don't want to take a peffectly working engine apart but at the same time it will give me piece of mind :/
    ah sigh!!!! I hate thinking about it pmsl
