300/440/550 towing a boat on a stock standup

[Fro Diesel]

thanks for all the responses! YOu guys are way better than my bros at mx6.com. I will take everyones advice, If i can't get a neighbor to do it then i will attempt to tow with the ski, I will keep checkin the pisser to make sure it doesn't get to hot, and cool it down if it does. the distance is just an estimate, actually distance is probably less than 2 miles now that i think of it going straight across the lake.

How do i know if the pump is cavitating? I know this will cause damage to the pump so how do i know, cuz i am sure i could potentially cavitate on flat water right?

slow is the key. Don't even try to get the thing on plane. You possibly "could" plane it out, but that would be way too much strain on the drive train.

You may need to carry extra gas btw..

When the pump cavitates the ski revs, vibrates A LOT and doesn't have any power. Towing will not cause it to cavitate, although it might cavitate while towing if you already have a pump/prop problem.

since the pump is only pushing water and it doenst know how fast the hull is going
it actually will not make much difference at all to the load on the driveline

its not like you have a tyre on the road straining
you just have water thrusting out the back

if you were to hold your ski flat out you will more than likely get heat soak in your engine and it wouldnt be a good idea

i would just cruize it along on your knees and you will be fine

make sure the rope is a good length other wise you will find that the thrust from the pump will be pushing the boat backwards

i have towed in boat before its not to bad at all just take it easy

What we decided we are going to do is just haul the boat out of the water on the trailer with brute force. We have enough people to do it. grandpa didn't want us to drive the truck down over the new grass to get the trailer hooked up, but my uncle finally talked some sense into him. I will post some pics if i my hands aren't on the trailer. It won't be fun or easy, but at the end of the day it will be done and we don't have to go across the lake in tow. Honeslt this is the best response i have enver gotten from a thread i posted on any site. I am hooked, so call me a lifer.

my friend has a stock kawi 650 and pulled me a couple miles on a 550 up on plane no prob at all but a boat is a diff story. Give someone 10-20 bucks gas will be half that anyways if the ski is working hard pulline something

If you fix your pump from sucking air before you tow there shouldn't be a problem unless your ski needs work already.. it will over heat if you keep a steady 3-6 mph speed without slowing down to a idle every so often (5 minutes) I towed 1 sunk ski and a broken blaster with 2 people hanging on to them for 4 miles on my SJ.... Another time a pontoon boat and my SJ tied close on a blaster for a good mile.. and last a blaster with my SJ about 2 miles hauling ass 35mph +, racing a guy with a SX650.. I did over heat once towing that blaster and a sunk SJ but after cooling down and taking a few breaks we made it back.

Just go real slow and don't overstrain the motor. Feel the pisser water for excessive heat.
I tow 1200cc Waverunner on plane w/ modded SJ
