OK so let me start by saying I messed up and I know it
When installing my new jet pump & impeller ( solas concord 10/18) I put the wrong impeller nose / boot seal on the impeller and did not realize that when i was pushing the the pump on the driveshaft was not sliding into the impeller any further and instead pushed the stop sleeve and bumper forward in the output sleeve enough that it allowed the carbon seal to advance forward enough to break the seal ( unknown to me )
I launch the ski get it started everything appears to be fine until I try to accelerate and immediately notice something is very wrong as it has almost zero thrust because (1) its sucking air through the carbon seal that is no longer working and aerating the impeller and (B) filling the engine compartment with lots of water (fresh) thankfully. I was quick enough to get it on the trailer before anything really bad happen and when we pulled it out saw water pouring from the drive shaft and immediately knew (Huston we have a problem) open the seat and see enough water in the compartment that I realized I was well on the way to sinking
I noticed the carbon seal was not functioning since its separated so I took the pump off noticed the impeller boot/seal was sized wrong ( too small) surmised that I likely pushed what ever maintains the drive shaft axial position in place out of location my engineering mind started searching for parts diagram and realized very quick what I broke or moved that device (Input shaft "stop sleeve and bumper") deeper into the input shaft allowing the carbon seal not to make contact anymore
Here is my questions:
First I know the drive shaft has to come out and I have the tools to do it -
Has anyone done this before or maybe had a stop sleeve move forward?
Can it be pulled back into location?
If not Can I remove the bad stop sleeve / bumper without pulling/removing the drive shaft PTO bellows and ball bearing attached to the motor
Are there any tricks to this procedure
Any Help is Greatly Appreciated
