    Default Jacuzzi jet drive vibrating boat

    Hey Guys, I'm new the boat world...at least working on them. I have a 1974 Hondo Jet boat with a Jacuzzi Jet (not sure how to tell what kind yet) hope you guys can tell me where it says the model. Anyway, out on the water, the boat starts vibrating and shaking hard. I turn it off, let it sit for about an hour start it back up no vibrations...until about 10 minutes later. Does this sound like a jet issue. The engine sounded smooth still...Need help!!!!!

    There should be a tag on the front thrust bearing housing that tells you the model. If not, take a picture and post it. We can tell you what you have. Need a little more info on the vibration. You aren't picking up trash or rocks in shallow water and then shutting it off and letting it fall back out are you?

    Jacuzzi pumps are mostly wj or yj pumps, if you do a search on both of them here in the jet section you will pretty easily be able to find pics of both and be able to identify which one you have. Best bet is to pull the hand hole cover and take a look. Before you pull the cover put the keys to the ignition in your pocket!!!!! Look for anything caught around the shaft or in the impeller. A tiny rock stuck in the impeller or fishing line around the shaft will produce a lot more vibration than you think. Also grab the pump shaft and try to move it back and forth, up and down, side to side. Any noticeable movement points to a bad bearing in my opinion. If this is the case a complete tear down and rebuild is in order. Message some of the guys that are on here a lot with what you find. Duane w/ htp, Tom with jet boat performance, etc. mostly everybody on the boards is great, but the guys that work on these for a living are awesome for sharing their knowledge free.

    WJ mixed flow jets were common in small Hondos a WJ can be easily Identified by a grease zerk/nipple dead nuts in the center top of the bowl (outside the boat) very occasionally we'll see a YJ (axial flow) in a larger Hondo Day Cruiser , best guess is you likely have a WJ in your boat if its an 18' , that said what you describe is really odd , unlike for example engine problems that can come and go , jets are fairly predictable and once a problem manifests it doesnt typically come and go ...Have you rolled under the boat with a bright flashlite and looked up into the jet or pulled the clean out cover and looked for debris ?


    There are some diagrams here on our Jacuzzi site that may help you identify your pump call if we can help JACUZZI DIAGRAMS, Jacuzzi Jet Drive Parts
