Getting ready to drop this in my boat. Is anyone running a 4 port bypass thermostat setup on your blown motors?

Thanks,

I do not have a picture of the nozzle. The boat is out in Blythe.

I replaced the Calgo cable once and installed a new Teleflex rotary system and did not make a difference. I replaced the Turbine trim that cam with the boat with a brand new unit and no change in the steering. Removed the rudder no change. I had Brad at River Speed and Sport in Blythe do a visual inspection and he said everything looked and felt ok on the trailer. I guess I will try a non-trim steering nozzle Memorial Day and see if that makes any difference. This is driving me crazy. Any ideas out there?   

I have a Advantage 20.5 closed bow, AT, with a ride plate and Turbine trim. The boat steers with zero effort at idle. Once any throttle is given to it becomes very hard (two hands and a ton of effort) to steer. I used to have a rudder and took it off and it didn't help.  I have changed steering and even replaced the trim with a new one and it has made zero difference. GS marine suggested that a Place Diverter may correct the problem because of the way the reverse is on the nozzle. On the American Turbine trim the reverse chute looks like a scoop into the oncoming water. Place Diverters have some aluminum cast onto the nozzle that allows a flat riding surface. Has anyone ran into this problem and does this sound like it can be a cure?

After a closer inspection the shaft did get into the bowl. I decided to take the pump to GS Marine. Greg had to send the bowl back to AT to be repaired and powdercoated. I hope to have everything back next week. Thanks for everyones offer to help.

The bowl bushings are what is egged out. It oesnt appear to have gotten into the bowl bore. It is a greasable bowl through the rear plug. I would like to take you up on your offer. can you PM me so we can exchange contact info and what parts I will need to purchase? Thanks for everyones help and support! This is what makes our sport great. Great people helping people. After I dissassembled my pump I thought I was going to miss out on a lot of boating this summer. I feel much better it was quite as bad as I thought.

Did you have to replace the suction housing. How do you check it. Do you reinstall every thing with new parts and spin the shaft and check for clearance? What if material was removed by the wear ring spinning, is there a thicker isolator to take up the difference?

While I was launching my boat 20.5 Advantage Classic closed deck AT-309 pump I fired it up as I was backing into the water I heard a large rattle and vibration from the jet. My son and I pulled it apart this weekend and found that the isolator rubber was missing and the wear ring was floating around. On the prior trip while I was greasing the pump I noticed my zerk for the bowl bushings was missing. I don't know how long it was missing. I replaced it and lubed the bushings. On inspection when I disassembled the pump the bowl bushings are also wasted and egged shaped. The end of the shaft is tore up. I already have the shaft repair kit on it so that should be a easy repair. The impellar is amazingly not in bad shape except were the area fits into the wear ring. How do I check the suction housing to be sure that the wear ring will still be centered? Or if it will even hold the wear ring snug enough? My bowls leading edges on the stator vanes are very worn and looks like I might need a bowl. Any advise will be greatly welcomed. I will try to post pictures tonight of the bowl and suction housing when I get home from work.

A split if everything is a direct change over.

Will a Berkley bowl interchange with an American Turbine AT-309 bowl. I t!oasted mine this weekend. Wear ring is loose with new insulator and the vanes are pretty jacked up. I dont have any picks. Want to find a resonable replacement to get back on the water.

I should have proof read my last responce. (to many beers)   I meant engine off one finger steering. It is just as hard to steer when recentering the steering as well as normal turning. The nozzle doesn't have any slop. I have had several people look at my steering connection at the pump and all  have agreed it looks fine. It has done this with two steering and nozzle set ups. How would I check the bowl? I dont know how it should look.
