Stubborn jet pump removal - 780 SLX
780slx. Day 3 now of soaking with penetrating and forcing. All bolts etc have come out first time with no effort but I can't break the pump housing seal. I have tried the 2x2 plank to force it but am reluctant to get heavy handed with it as the housing looks like it could crack easy.
Any sugestions or just keep at it ? How strong is the housing ? I definitely need to strip it as the prop is in poor cond.

I doubt you will break it. Use a 2x4 for more leverage. It will flex less than a 2x2. Just use steady even pressure and it should pop free.

Apply heat with a propane torch. That never fails.

Do you have the steering and pump exit nozzles removed?
Have you seen this thread showing how to lever a long 2x4 to crack the pump free from the pump base?

Done it. Got mad and used a 6ft scoffold pole. Have now found out the drive shaft and crank coupling are fubar. So thats stuffed up that job big time. no wonder when I gave it a 30 min water test it hit the rev limiter instantly and slowly picked up speed.That proberbly explains the noise I first posted about. So I now need a second hand driveshaft and coupling if thats possible in the uk otherwise its scrap. If thats the case that I cant get the parts without spending big money I will just weld it up solid and ride it till it dies.

If its an extended pump it will have a 4 inch extension between the hull and the stator. would you be able to take a picture of the pump tunnel from behind your ski.. tha would give us a good idea if you have extended pump or not
