Hey guys,
I'm an experienced mechanic but new to the jet boat world and one of my u joints went bad over the weekend and I have a few questions that about replacement. I have a sport pack 454 with a Dominator jet. There is a bell housing with about a 3" hole in it I'm assuming for inspection and servicing? I removed the cover from the hole and can see the grenade u joint, its the one closest to the jet. Now for my questions
1) It looks like I will need to pull the motor so when I do will the splined yoke slide of the pump shaft by moving the engine forward?
2) I have through transom exhaust with 4" rubber hoses that connect the manifolds to the pipes going through the transom. Will these come off as I move the engine forward? They seem too stiff to just pull out of the way. I have a few more questions but will wait to see if I'm on the right track. Thank you for any help or suggestions!

Great, Thank you! Is there any trick to lining up the splines during installation?

Thanks fro the help! Pulled the motor Friday after work swapped out the U joint assembly and had the motor back in and fired up the next morning. Gonna test it this comming weekend at Elsinore
