hello I am new to the site and new to the jet boat world but have been checking out the site for a wile and you guys are awesome and always seem to have the answer im looking for. I have a 1977 omega 21 foot open bow with a bbf and Jacuzzi yj with an energizer kit on it. like I said im new to all of this and it took me a lot of research to find out what jet I even had but anyways when I put my boat in the water and put it in forward or reverse it went know where even when the bowl was going up and down when I went from forward and reverse so I gave it a little gas and then it seemed like it slipped into gear per say and I was able to go but so I didn't think any thing of it and it worked fine all day. put it on the trailer and the next day the same thing except this time I was cruising at 3000 rpm's which is usually about 35-40 on gps and I lost all power and was going like 10 mph. my first thought is I sucked something so I looked under the boat and there was a thing that looked like a plastic shoe lace but was about the same diameter as the impeller and wrapped up in it so I pulled it out and started to go again and same problem so now im lost I pulled the bowl off the boat today and nothing in the veins of the bowl or in the impeller so any help would be much appreciated
One of the hardest to read posts ever!

First off, the pump was probably cavitating when you first launched it. (Trapped air in the pump, completely normal) but to help this, and combat another problem, always double or triple dip the boat when backing it in. Back it in, leave it sit for a minute, pull it back out, and back it in again. This clears the intake from any possible road crap, grocery bags, rocks, from the trailering experience, and helps "prime the pump" for firing.
Second, if you sucked up something the "same diameter as the impeller".......you got serious issues son........I'd be more willing to believe you sucked up an anchor rope, ski rope, case of used diapers, 25 million tampons, something, or other that has wrapped itself around the shaft so tightly it looks like one piece.
No matter what, whatever it is, THAT is your problem, and it needs to be removed!
