    Default New Jet Boat Owner Looking for help

    Hello to all, my name is Sam and I live in east TN. My girlfriend recently inherited a Jet boat when her dad passed away and we finally found time and a way to go get it from Knoxville. I am a fisherman and this is not exactly the jet boat I have been dreaming about, but itís a free boat and we are going to try and at least take it out a few times and play with it to see how we like it. My problem is that I donít know anything about jet boats. The boat is an 82 model I think and is made by Sundancer. It has a 454 Big Block with a marine jet drive (something on the back of the engine says Glenwood, maybe this is a brand name of the jet drive?) This thing looks mean and fast. He used it regularly up until he got sick and it hasnít seen the water in about 7-9 years. It has been started from time to time, but nothing at all done to it in the last 4 years. I think I can handle reviving the Big Block, but all this jet stuff is new to me. My biggest worry is how does this thing cool the Big Block? I see no radiator, so I am pretty sure that the jet drive somehow pumps water through the engine to cool it. I am pretty sure I can start this thing in my driveway as long as I just let it idle and donít give it heck. Problem is that I know there needs to be water hooked up to it somehow, but I canít figure out how to do that. Then when I do get it started and running again I need to figure out what all a jet requires to run. Does it need to be greased each time? (seems like I have heard something about doing that) What kind of maintenance things should I do to keep the pump in good shape?
    Like I said I am new to this and am really just looking for advice on how to go about getting this thing running without doing any damage to the engine or the pump. Should I unhook the drive line to the pump while messing with the engine in my driveway? Can I just hook a garden hose up to the engine and let her rip? Maybe some of you jet boat owners can give me some pointers. Any info would be greatly appreciated! Really donít want to screw this thing up because of lack of knowledge. Also does anyone know anything else about this boat just from looking at it? Like what itís called, what do you call this type of boat? Does anyone on here have a boat similar to this that lives here in east TN, Boone Lake is where we will be running this thing if we ever get it going. Here are some pics.

    Hey Sam, nice looking boat actually. Here's a couple tips to get you started. If you can , it's better to disconnect the jet (drive line) from the motor to run it on the trailer. If you can't then It's not a bad idea to run some water into the jet while it's running to keep the pump wear ring lubed and cool. If you look inside the boat on the driver side rear, you should see a hose that's probably a 5/8 heater hose coming from the pump to the motor. This is the feed line. The jet feeds water to the motor to where a water pump would mount at the front of the motor, and exits the motor at the thermostat housing.
    There probably is a fitting in the feed hose coming from the pump at the back of the motor with a coupler in it you can disconnect and screw a garden hose to. When your ready to start the boat, start the motor first, then turn on the water about 1/4 to1/2 way not full blast. You will see water coming out of dump hole in the back. When you're ready to shut the motor off, turn the water off first, then shut the motor off. With this type of cooling system and those headers its very easy to over pressurize the system and end up hydro locking the motor. Make sure no water is being pushed through the motor when the engine is off. This shoud at least get you started and see if it runs. If you are mechanical,in simple terms, it's just a truck motor in a boat.

    As far as the pump, they are low maintenance. There may be a grease fitting if you look into the pump at the end of the shaft. The 2 little plugs on top of the bowl can be removed and you can push gear oil in 1 hole until it comes ou the other hole. there is probable a grease fitting at the main bearing by the drive shaft and maybe grease fittins at the u-joints. That's basicaslly it to start. This should be enough info to get you into trouble. Good luck!

    Sam,
    welcome to our board. We hope you enjoy your jet boat as we do. You certainly got a great deal on it.

    The 'Glenwood" on your rear mount is the brand name of that mount.
    Your jet drive itself should have it name cast into it behind the transom.

    All the jets I have seen have a pressure outlet inside the boat at the very back. It is a pipe thread and should already be hooked up and go to your engine to cool it. That is how engines are cooled in jets. In that same area, look for a garden hose fitting attachment. Most boats have them, if yours does not, you should add one. It is not good to fire the motor dry because you can damamge the seals in the jet drive.
    You can, however, fire your engine out of the water if you attach a garden hose and let it run. This will not only cool the engine but, keep water in the pump so it will not be damamged.
    There is a unit on the market, called a jet a way. This part goes between the jet drive and the engine. It allows a neutral so you do not need to run your hose but, it is doubtful your boat has it because it is expensive and normally only used on supercharged or high hp applications. more to come

    When you first put it in the water, expect to take some time to familiairize your self with how jets work. In some ways, the boat will act normal, in other ways it is very different.

    Remember, the thrust of the jet is what turns the boat! If you lift off the throttle to turn to avoid someothing/someone, the boat will keep going straight no matter how much you turn the wheel!

    Jets can be tricky at low speed, esp to a beginner. Remember, thrust turns and manuevers the boat.
    Some of thier vitures is they can operate in shallow water. You do not have to worry about the prop or rudder being damaged. However, be careful when applying power in the shallows! Afterall, the jet drive is a big pump and it can easily suck up rock, vines, branches, etc and that will plug up the drive and leave you stuck.

    Should you ever find yourself going over a ski line or other debris in the water, I just shut off my engine and coast through it, then fire the engine and continue.

    Others here can help to answer your questions.

    Be easy on the water and learn how they turn, etc. If you are used to a boat with a rudder, this is very different, esp at low speeds.

    You got a well sought after boat that holds its value. From the pictures im fairly certian its a TX-19 Gullwing. Do you know the first 3 letters of the HIN. It looks like a Clark TX-19 with the raised back. It look to be in good overall condition. NICE Float!!!!!

    Thanks to all for all the info and comments. Also a big thanks to sturat for giving me some killer info and pointers over the phone tonight. I got the drive line unhooked tonight and did a little looking over the boat to try and see how she works. I am sure I will have some more questions before its all over, but I have a game plan now!

    Thanks again to all!!!!

    Another thought. for your first outing you might want to hook up with some other Jet Boaters in your area. See If there is a group here on PB. Jet owners are a great group and I'm sure each and every guy on the beach will be more than happy to show you jet boat etiquette and techniques. Safe boating and have fun.

    Here are some more pics that may help tell some things about this boat:



    Trying to figure out the fuel system. Does this thing auto select the tank or do you have to manually do it with a switch?

    Found this switch beside the ignition (might be for fuel select or could be for the bilge pump?) anyone know?


    Looks like this thing is a TX-19 (which I don't know what that is exactly, but I take it that is the model?)
    Can anyone tell me more info on this boat with the help of the HID?


    Any help would be greatly appreciated!!!
    Sam
