hey everyone
so i am a new guy to jetski forums etc etc
i picked up 2 jetskis a 87 yamaha and a 97 montego dlx on the tiger shark there are 2 threaded holes 1 on each side i cant find anywhere what they are for i found drain plugs on ebay which look like they will fit in the holes but i dont know if i am suppost to put plugs in while in the water ??? any help would be reallly great , also are there any fluids that need to be changed on a reg. basis thanks in advance

willc32

if anyone knows about this pleaseeeee help thanks

yes they are drain plugs so DO NOT FORGET to close the holes when you go on the water or you will sink lol dont wont be good and when u going home remove the plugs so any water in the hull will drain out and no there is no fluids you have to change... are you going with premix??

willc32

on the tigershark i wont premix it has a seperate oil cap on the yamaha i have to premix seem like a pain to do it though if you have anysuggestions on oil il take them i went to bike shop they sold me a gallon of marine 2 stroke for 30$ seems high ,from what i figured out one of the holes is for the bilge pump and ithink the other is for if you want to hook a hose to it but would that one get plugged when in water ?

jaydandzach

are you talking about the one on the back or the one on the sides?

willc32

the ones on the side i didnt even look at the back of the skis yet crap prolly should have they are pushed up to the garage so i can only see the front and sides right now

jaydandzach

oh ok yes you leave them alone DO NOT BLOCK THEM the left one is the pisser takes the water from the motor and then out that port and the right one is for the pump. if i was you i would go premix cuz them oil pumps do go bad and you will never know when its about to go.... do you even know if the pump is good?

willc32

I have no idea i assume it is but thats just a guess i know not one thing about jet skis found them on craigslist for 1500 for the pair guy said they both run good so like a dummy i bought them without knowing anything or testing anything

jaydandzach

a thats no good. if that pump goes say bye to ur motor so if i was you i really would buy a block off kit for around 10.00 and go premix 40:1 and your motor will last a really long time

willc32

where do you buy that from are they universal ? also anysuggestions on oil and is there any easy way to meausre it i tried premixing the yamaha not sure how accurate i got it i used a measuring cup from the kitchen im assume there is a better way ? thanks for all the help
