1995 gtx pump shaft options

[Copenhagen]

hello,

new to this forum, i have a 1995 gtx and was wondering since some parts are no longer available, what options i have for a different pump shaft setup for my ski and does anyone have this combo for sale.

thanks

what options? go on ebay and get a used one. very common-very cheap. virtually all seadoo drive shafts are the same in the early years. do you have the flat carbon disc, or the regular lip-type seal? btw, why do you need a new shaft?

hello,

not sure that i do need a new shaft just started taking the unit apart. was using the ski yesturday and the driveshaft started to slip when power was applied. i took the reverse mechanism off and got to looking at the impellor and its shot. also driveshaft has alot of for and aft movement. im assuming since i have not seen the splines on the shaft yet, that they are either stripped or pretty close to being stripped. looking at the prices for new stuff figured it would be quicker and cheaper to replace the whole assy complete then try to rebuild. any help u might be able to suggest would be greatly appreciated.

thanks

basically,

what im trying to do is replace the jetpump with a refurbed unit that will work in thei 95 gtx and replace the shaft.

thanks.

It sounds like the problem you might have is the end play is excessive. This causes the shaft to move in and out. Here is how you check for the end shaft play. The small parts you need are going to be lots cheaper than replacing the complete unit. It sounds like you need a impeller and wear ring, and maybe a anti-knock pusher on the shaft end. Here is how yu chek the end play. End play of the impeller shaft is checked with the shaft in housing, without impeller and cover installed. Retain housing in a soft jaw vise making sure not to damage the housing lug. Set a dial gauge and position its tip on the end of the shaft. Check the play by pushing and pulling. The maximum permissible end play is (new) 0.12-0.54 mm (.005-.021 in.) Excessive play comes from a worn anti-knock pusher inside cover and wear of the impeller shaft nose. The wear limit of the pusher is the measurement of the outside end of the pusher to the bottom of the shaft.( not to the opposite end) The wear limit is 8.0mm (.315in).

you could see the driveshaft slip? inside the hull? or were feeling it? if shaft slips at motor, you need PTO also. the shaft is stainless, and the 2 ends are steel. if shaft is hurt it also damaged whatever end the stripped splines were in.
