    "Hi guys, this isn't related to your question, but I need some info on the funjet boat.

    For a college project, my team is building a jet boat out of a funjet hull. My friend got the hull while on vacation in Arkansas at a place near his relatives. Anyway, I'm in Miami and he's in Denver (the boat is still in Arkansas).

    We need to know the exact length and width of the funjet as we are making plans to bring it down to
    Miami. Unfortunelty, he didn't precisely measure the boat when we purchased it.

    Were there different models with different length or did all the years have the same dimensions?

    Please help because there is no info on the web

    "How ya doing guys,
    I am having the same troubles you are with my FunJet 87', but I need the exhaust manifold. Mine cracked, I think due to excessive vibration. I would love to find someone who makes these parts. If the engine was made by Yamaha, wouldn't they be the ones to have the parts? Anyway, happy hunting, if you find anything please post it and I will do the same. Anyone heard of someone changing out the engine and drive for a newer system?"

You can buy it from this website for $26.95, https://www.buypenton.com/ProductDetail.asp?PRDID=497

    "I have an 88 Yamaha Funjet. The jet pump is a Morita jet pump. I need the nozzle and reverse gate portion of the jet drive myself, the part that sticks out of the back of the hull.

    I imagine that Yamaha three cylinder outboard power heads will fit on it."

    I could take a pic of mine. Yamaha engine. I'm trying to get the steering nozzle parts that mount outside of the hull where the jetstream of water comes out. I'm not holding on to any extra parts.

    I would greatly appreciate that if you could take a picture of it for me. I am missing something where the cable adapts to the linkage. Apparently I am going to have to build a cable because I am finding it next to impossible to find parts.

    have you been able to drive your boat since you have had it? I am wondering how powerful it actually is. They had the throttle rigged when I bought it. I am trying to get it right. It seems fun but some people say they have actually pulled a skier with their boat. Mine does not seem to have enough accellaration to do that. I am wondering it it was limited on throttle from being rigged up.

    Default "I've used it enough to ha

    "I've used it enough to have my own riot or two. Fishermen throw rocks at me when I go by the second time up a creek.

    I'm sure mine would pull a skier but I didn't do that.

    Mine would run 45mph with Splitfire plugs on 93 octane mix. The condition of the plugs and the fuel octane seem to make a difference in how many rpm I could get out of it.

    The Splitfires were good for an extra 500 rpm.

    Mine could turn and jump its own wake and catch air.

    I could scream down the creek, crank the wheel around and slide backwards down the creek, which is a hoot. The bilge pump gets a workout for a few minutes after that. They won't sink and they won't turn over. If they could, mine would have.

    The amount of weight in the boat seems to really matter. 400 pounds, fuel and passengers, seems to max it out. Then it won't plane.

    Basically, I've gotten too big to take an adult passenger with me if I take some extra fuel.

    Taking fuel along is a good idea. It loves plenty of fuel.

    Maybe I'll go out there and take a pic if it isn't raining for a little while."

    "I would greatly appreciate that. What model number are the spark plugs you are using. LOL, don't believe that thing wont flipp over. I was doing the same as you.... Flying throught the creek and doing 180s. When I put my sister in and got flying down the resevor and turned the wheel it flipped over. WE both went over with it and luckily we werent wearing life vest. WE came out and up with no problem. I thought for sure it was going to sink. Once I flipped it back over it bilged and bilged forever. Needless to say we had so much water we had to be towed in. The engine would not crank. I let it cool down, took out the plugs and cranked it over for a few times to get all the water out. About an hour later it cranked right up. Does yours have alot of take off speed? That is where mine seems to lack and once it gets going it bounces alot. ARe you able to get yours to plane out so it is a smooth ride once it is going?"

    Default "Ok. I went out there and too

    "Ok. I went out there and took some pics. This site won't upload them unless they are dinky. I set the camera on a lower setting but it still won't do it.
    You owe me big for this. 32 degrees, spitting something between rain and ice, 20 mph wind, everything is wet. I had to hold the camera against the hull to keep the shaking down to a roar. Brrrr. It is worse like this than if it was frozen already.

    You are going to have to give me an email to send the pics to. I'm tired of screwing with this uploader. Not a computer nerd.

    If you catch a wave or roller wrong, I could see how you could turn it over, but I never have been able to and I've tried. Congratulations. Mostly, I just get whiplash.

    The aluminum plate under the jetdrive can be bent to adjust the trim. Trim will change how it goes on plane, and how it holeshots. Since it isn't an adjustable trim, you have to find a compromise. But you are trying to keep the nose down but not too far. You do have to keep the water intake under the jet pump in the water, so that is a limiting factor, too. You don't want much hull in front of that in the water.

    I really think a power trim would improve these things.

    I also think a bigger Yamaha outboard powerhead on the jetpump would improve things. But it would just make the gas consumption worse and it is already terrible.

    Yes, I can get it smooth, but I stay off of the big, busy lakes. I hunt glassy parts of rivers and creeks.

    I often go upstream in canoe creeks, but the canoeists and the canoe rental people think they own the creeks and have a fit. I'm surprised I don't get shot. These eco-freaks here have been getting public access boat ramps taken out every time they build a new bridge, so the rest of us can't get into creeks and rivers we have been using our whole lives. Canoe and campground rental outfits along the creeks have political pull. I'm seeing fishermen get arrested for fishing the banks that they have been fishing since their grandpas took them fishing there."

    I am looking for a fuel pump for a 1987 Funjet. Can anyone guide me to a fuel pump. I bought the service manual and they have a diaghram of the part if a picture is needed. I may have a complete engine worth of parts for this baby if I don't find some parts soon. I love the boat but keeping it going is very hard without some parts. Please help
