so now,, here's where I was at...rocket out of the hole...great mid range...but something was still going on at faster speed..it only like to bust through rollers straight on..if not, it would pitch side to side and start to bow steer..so back to the straight edge and the looking process ....what I found was the outer edge of the lower cav plates where below the water line, and as soon a s you tried to trim up..they would grab water... as long and they were in smooth water...they did nothing but cause drag.... but in rollers and chop... the drag would chage side to side.... and cause the boat to steer .... pretty wild ride on speed.....so.... I started looking at different lowers...what I noticed, any of the performace lowers didn't have the big wrap around cav plates... and all of the out board lowers that had jack plate type set ups didn't have them either.... so I did a mod to the stock ones....it was gonna cost 20k for two new imco lowers... and really all I was gonna gain was lowers that didn't have the cav plates..and what were the lowers worth..1000 buck each???? and if the idea didn't work....I still had to buy new lowers....so I got lucky...and it worked...
