nautica rib jet 10- bow too low- boat plowing

Hi, When the boat gets on plane, the nose comes down too far and it is plowing making it very difficult to steer and handle. I'm pretty sure that I can't do anything with the jet pump to compensate for this, and I can't move any weight out of the front to the back; so asking if there is anything I can do to the underside of the hull to get the nose to stay up. Thanks.

Yes, reverse bucket all the way up. No trim on pump. No parts available to retrofit the pump. Nothing can be done at the pump. Looking for another solution. thanks.

Dont know the make up of the boat but have you checked for something making it bow heavy? Maybe water trapped somewhere it shouldnt or saturated bouyancy foam?

Has the pump been installed correctly to the transom? I appreciate there is no trim adjustment from the helm but could there be a means of moving / setting the nozzle angle manually?
Is there water in the bow of the boat you don't know about which would affect the trim?

Post a picture of the pump if its a standard Yamaha pump which is likely if using a 701 motor then trim options are available both from other Yamahas and aftermarket

Attached a picture. Not mine but same boat and pump. Pump is for a '97 yamaha wave venture. These boats have the fuel tank right up in the nose and the engine sits pretty far forward. No water trapped, etc. Pump mounts to bottom of boat with no way to shim or adjust. Have heard of pump wedges to turn nozzle into 5 degree up angle, but haven't been able to find one for that pump. Thanks.
