    The Malaysian police that travel the Malacca straits do not like Arnesons because of the rooster tail.

    In the bright sunshine and even a moonlit night the rooster tail can be seen miles away as no one else has them around here it is pretty obvious to smugglers and other undesirables that the police are coming.

    There,-- I can't get it any more simple,-- jeesh

    I dont think Arnesons rams are as deep as 30 feet Steve, and as for rooster tails if you new what caused them you would know that different drives don't have them.


    Mas,-- hang on Im coming with you, start the engine quick lets get out of here before any more,------ experts turn up.

    Thank you Steve H, any ideas as to why no growth???? kinda puzzling..... All I can think of is that the hydraulic fluid is stickey (stops in the metal) and is toxic to much marine growth. A new antifoul coat chemical!!!!!!

    Good point Longie, The quest is still ON?????????????????????????????????????????????????????????????????????????????????????

    I really don't know. I am not an authority of any kind on this topic other than my personal observations and experiances owning, operating and servicing the Arneson drive. I am starting to believe that this is a very minor issue with Arnesons if it is a issue at all. I do know that the rubber boot that covers the ball and socket is not meant to be water tight. It is strictly used to keep marine growth from growing on the ball section and then tearing out the o ring seal. I'm sure you could buy some rubber covers for the hydraulic rams that would serve the same purpose. I have purchased small ones for the drive and tab indicator cables that are under the water line and they seem to last quite a while.

    The aircraft was in Truck Island Lagoon, ( Chuuk if you are a local) no fresh water near by. Very warm salt water in the mid 80's.

    Some drives Arneson and Zf for instance are movable, they steer and trim. There are more drives fall into this catagory.

    Other drives such as Levi, Flexidrive have a tunnel rudder over the top of the propeller re-directing the rooster tail.

    Remember also that all that water going up helps push the stern down helping with bow lift at higher speeds. Lack of bow lift is a problem that all surface drives suffer from.
    When I installed the Arnesons I used the splash gaurds over the prop trying to tame the rooster some. Didn't seem to help much. I have since taken them off. Arneson doesn't use them anymore anyway. I have since had a larger swim step made. Now I can finally see behind me. I do not have the bow lift I used to, but it is not a problem unless I am WOT.

    Here is the view from inside the boat while at cruise power with the old drives.

    Don't worry westie, nothing too intellectual - just boats doing a pass for the home video camera. Check the others - more of the same.... Some with big rooster tails (singing "cock a doodle do" and others seeming to say "any cock will doo")

    The Levi style does not produce such a "mark" for those pirates 'et al' to see
    if they are hiding from police etc..... The inverted U rudder assembly...

    Ask westie, I hope he is enjoying the joke.

    Read the other (sensible thread) on surface drives for reference point

    Driveling in drivel thread where this is acceptable as nothing of value to me to learn here

    Then why do you keep coming back?

    Most of the drivel has came from you.

    Most of your replys have been biased and insulting. I think this thread should just die. But I doubt that you can control yourself enough to let that happen.

    In the Arneson Drive owner's manual I have, it is reccomended to fully raise the drives to prevent any fouling of the trim cylinder pistons. Then, on a regular basis, turn the helm lock to lock, which will prevent fouling of the steering cylinder pistons.

    OBVIOUSLY, the more severe your fouling conditions, the more frequently you should cycle the steering cylindersto prevent a barnacle larva attaching to the piston and getting it's start in life.

    In 17 years of running a yacht with Arneson drives, in many varied climes, the only barnacle issues I have had were with build-up on the flexible rubber boot which covers the thrust ball and socket, and growth on the aeroquip hydraulic lines from the transom to the cylinder.

    I have met Rik Wimp, and had several email exchanges with him when specing out new drives, and have always found him to be very knowledgeable, and very helpful as well.

    I can only imagine that someone who has said he wasn't helpful may have discovered that Mr. Wimp does not suffer fools lightly, which is evident in his postings here.

    With that said, there are several different option out there for someone looking for Arneson Drives. I am only familiar intimately with the Arneson Drives, and have found their only drawback to be noise. If I were building a fast yacht today and was not hypersensitive to noise and vibration, I would use the Arneson drives. If noise and vibration were high priorities, then the natural choice would be waterjets.
