please help loud rattle either from back or under jet ski 97 montego

it can be the prop start out by removeing the prop and the driveshaft and see if you still have that sound

oh sorry yes start it and hear if the sound is still there then report back lol

no just remove the 4 bolts on the back of the ski and the rubber water hose and everything will come out then i dont know if you have the update shaft that it screws to the motor or it just slids in to the motor but no matter what the shaft has to come out so you wont damage the bearing

did you remove the prop all the way out?

it can be 3 things 1 your wear ring is no good 2 you need to rebuild your pump 3 your motor needs to be aline with your prop

you better hope its not your wear ring cuz its a $300 plus part. you must remove the prop with the housing so you can spine the prop by hand woth the prop next to your ear and listen if thats the sound you hear. lets not worrie about the wear ring right now so do that fist then i will tell you how to aline the motor

if you can remove the driveshaft and remove the floting bearing and turn the bearings with your fingers if its ok then see if your shaft is not bent and look at your motor coupler see if it does not have play

motor coupler is where the driveshaft goes into.. that should NOT have any play... next step we will aline the motor

first do it with your hand then with the shaft

how did the pump go back in did you have to force or move the driveshaft to install the prop back into the wear ring?

jet pump is the housing where the prop is.. now look at the prop is it hitting the wear ring?

ok you said with the pump removed and the driveshaft removed the motor was making the sound?

i really do think that your prop is hitting the wear ring... see if you can shake your motor by hand like see if you can moe your motor up and down and side to side.

sounds like you need to rebuild your pump

go to my website Tigershark and go to the hard to find parts page and click on all the links till you find the cheapest website that has the bearings and plus if you dont have a manual for your jetski you can also download it on my website for free. my website has all the info you need all for free let me know how it works out for you

yes just replace everything

no just the bearings and the o-rings

what state you from?

oic i was going to ask if your from ma just bring it to my shop so i can help you out.... just take anykind of wrench that will fit the bolt and hold the prop with a towel so you wont heart your hand and just remove the bolt
