    GSX sponsons questions

    Ok so one of mine cracked last summer, mines a 97 GSX and I was going to either replace it with the same one or get after market but I don't want to loose top speed. I was reading some info on beach house and they have an adjustable one which seem interesting. But will I loose top speed with these no matter how they are set? They say they give lift but?

    I was also told that the GSXL have better sponsons is this true and how do they differ?

    Thanks

    Somehow I missed your post. No sponsons will kill top end, they just make it turn harder. I prefer Worx Sponsons. Do a search, there are many on her that have hand built sponsons for GSX's, you may want to buy a pair from them.

    We had a thread not too long ago talking about making our own sponsons. I'm going to make a pair for myself and another guy as soon as I get time.

    really? I thought they did, by adding more drag? Well that's good to know.

    Sponsons add no drag running in a straight line. Somebody mis-informed you.

    You could probably get some lift if you stepped the backing plate, but then they would have to sick out atleast an inch on top...and the lift would be minimal at GSX speeds...you need to be near or above 70 to see any major lift to gain speed, like on the GPR hull...

    I've made many GSX sponsons in the past...they really wake up the hull.

    What are you referring to when you say backing plates?

    Any aftermarket unit uses a backing plate that bolts directly to the hull and does nto move. The blades then can be adjusted to several positions in a few minutes, without having to tear the hull apart again.

    The units I built for mine when my BeachHouse units broke on my GSXL, I made them thicker and stronger, along with 12-way adjustable instead of the Beach House 6-way...
