when im goin through a no wake i feel a shifty vibration in the hull like white caps hitting it er smtn weird like that? like a light push pull? anyone have any ideas on what could be causing it?

How rough (Lopey) is your idle? (Hot cam?). Could be loose motor mount, foot, or plate, as a minor issue. Not gonna go where else it COULD be......   I'm assuming it doesn't happen at any speed.......

Check driveline to crank bolts.

IRRebel, I CAN ONLY FEEL THE VIBRATION WHEN I'M GOING AT SLOW SPEEDS, LIKE IN THE NO WAKE. IV'E CHECKED MOUNTS ETC. ALL SEEMS WELL?

Are you drinking he bong water?    

Tom from  JBP may be able to add some more in sight....

may have just stumped the band here   some motor box constrution boats tend to "squirm" (lengthwise twist) rolling thru wakes when the floor structure breaks down , makes for a wierd feeling while driving , conversley "vibration" is typically shaft bearings or bushings or.. a driveline yoke to pump shaft wear deal (we call it machine noise)  , generally worse on the trailer , also audible at slow speeds in the H20 and typically disipates with an impeller load (rpm increase)  Tom  

Flywheel or flexplate loose? Harmonic tight? driveline, how long has this been going on?

Well the problem is my pump was goin bad in a big way (I found metal shavings in the jet/motor cooling hoses). I was hydro locking at The Delta and I started to suspect something clogging waterflow. I pulled off hose that feeds BBF and found metal shavings (aluminum), then went to front of moter where impeller set up is and took about a TBL. spoon of fillings blocking the flow path. Gonna rebuild pump W/(Dave GT BOATS) thanks for all input givin.

Can you give me contact information for GT Boats.  I'm curious if this company is related to the GT Boats that was in Pacheco during the late 70's, early 80's.

Thanks
