I said I would give an opinion on the Hydrojet Pro talked to Jeff at Cobra Jet. I had his originals, and was really was ok with them; but Pops drives the boat occasionally and wanted a bit more control. I bought the Hydrojet Pro fins as an upgrade to the original style Cobra Jet fins; because they were local, so I drove out to get a set. I got to talk to the owner and the kid who designed them, who of course told me they were the best thing out there. They said they had already sold over 50 sets in their first month of production and that everybody loved them. I assumed the ones that loved them never had steering fins before. They operate out of an airplane hangar with many nice planes; but they had no inventory to choose from like I was told, and I had to wait for them to put a set together; even though I had called in advance. So I went and grabbed lunch and killed an hour or two and went back and they only had one complete; which kind of ticked me off so I ended up leaving and had them ship them to me.
Let me start by saying that they asked me to share what I thought of them good or bad; so here goes. I really wanted to like them; but it was NOT an upgrade. It was actually a downgrade. I was not happy with the performance and told them I would be sending them back for a full refund. I sent them back and am awaiting the refund now. They just don't work, they do not operate as claimed, and have issues which I will try to explain.
First, the whole goal of steering fins is to compensate for lack of low speed steering; but because they are mounted to the reverse gates, when you bump the throttles forward in no wake mode the fins come up and provide little help. I never realized how far the buckets opened in no wake; but they actually open up quite a bit with little difference from WOT. And after having them; I don't think the extra strain from mounting them on the buckets could be very good.
As you can see, they are already up with the throttles in no wake mode; and the only assistance is from the very bottom of that lower point.
Second, They mess with the wake. They throw water up in the air which sucks for tubers.
Third, I had an issue with them binding up the throttles a couple of times after anchoring, and had to jiggle them up and down to get the throttles back.
And finally, and probably the thing that ticked me off the most is that if you don't put the throttles in reverse and the steering straight when anchoring; when you get back in they hit the ladder, and if turned just right, they stick out where you can bang your leg on them...and let me tell you...those points hurt.
Not fun pulling yourself up and hitting you leg on that!
So I decided to look at what else was out there, and decided the new Cobra Jet Venom Ultimates were the best thing out there for me, so I ordered up a set of them. They seem to be the innovator when it comes to jetboat steering, and they have a butt load of patents for their products. Plus I am not a fan of the plastic fins because I have heard several others that have had screws pull through on hard turns, and the Cobras are heavy duty stainless like what is used in aircraft, and I never had an issue with the originals which were stainless, and had been on the boat since 2006. Cobra Jet also has an add-on called Fangs which I would love to get too; but cash is tight, so I will have to see how the Cobra Jet Venom Ultimates perform without them.
Hope this helps.....I will let you know what I think about the Cobra Jet Venom Ultimates after I get a chance to try them out.
