    Default Transom mounted ski/tow

    Are there any drawbacks/benefits of having a transom mounted ski eye on the a jet boat? I ask because I don't know if I want to have one bolted to my engine.

    drawback is the rope is low and gets caught in the water

    I have one on my boat and there are some downfalls. When pulling a slalom skier of even decent ability, the back of the boat is pulled side to side quite a bit. Even though I've towed a few boats in with the rope tied to it, it's pretty nerve racking thinking if the transom is going to hold up or not.
    The good thing about it is it gives a good place to tie down the bimini when it's rolled up.

    You can see the little bungie in this pic that's wrapped around the bimini and the transom ski tow.

    Thats what I was afraid of. I would always be worrying about the transom just tearing off lol. You have an awesome looking motor by the way

    Thanks! It's had many changes to it over the past couple of years but it's mostly all looks and no go.....compared to most people here.

    easy to put backing plates inside the transom , will greatly reinforce the transom eyes.

    Is there any concern about engine mounted ski tows when you have a 3 point engine mount? That seems like all the stress from the skier would be acting through a long lever arm, basically causing the bellhousing to shove straight down on the pump nose (and thereby shoving straight down on the intake). It concerns me that all that is holding the intake on is some epoxy and screws. In my boat, the freeboard is pretty high, so the ski tow would be even taller than typical, which increases the lever arm problem even more.
    Something tells me that popping the seal between the intake and the hull would instantly turn a day on the water into a doggie paddling exercise.

    I made a backing plate out of 3/8 aluminum about 5 inches wide and 3 inches tall behind this ski tow. Seems to work for me.

    Factory one on Moo seems fine! Towed in many bigger boats with it, including my own, with no issues. I never worried about it "ripping the transom off"

    Transom's probably much stronger than all the welds and steel on any spindley block mounted, Rebar looking Ski Tow anyway, IMHO.

    As far as a skier dragging the a$$ of the boat around, if that is a real issue, and you then mount it even higher...........well, you don't have to have a physics degree to surmise the result! Put a rudder on it, should help that, and make sure the jet pump intake side fins are still in place!

    i like the engine mount ski bar, never worried about the pressure on the pump nose mines bin good since 79. if your worried about the pump nose and the transom, and the boat being pulled around mount the bar in front of the motor tie the base into the stringers attach to the top of motor or water pump bolts, this will help with pulling around the back of the boat the lever will push down on the motor mounts. and the transome receives no pressure other than the jet pushing back.

    The problem with a engine mount ski tow is that the rope gets burnt on the headers. The problem with a transom mount ski tow is that it is harder for the skier to get up especially if they lack experience. If you plan on pull a apparatus such as a tube or torpedo than the strain against the mount point is increased . But lets face it a typical ski rope is only good for 3 to 4 hundred pounds max.

    Sorry Ray, mounting it higher on the transom does very little to help prevent the boat from being pulled around. It is much better to put the ski tow on the front of the engine which moves the pivot point forward. A higher mounted ski tow does make it easier for a skier or wakeboarder to get up easier though.
