fixed the problem buy replacing one injecter. The screen is pretty easy to see if there is junk in it. I'm sorry but without a factory scan tool, You can't cut out the injecter by itself.

Well found what I thought was the culprit, a loose separator filter. But turned out not the case. So after verifying i had good injector pressure with a fuel injector gauge loaned by a mech friend, I started pulling off the injector banks. I popped each injector out one by one and low and behold 6 out of 8 had fine particles of rusty looking gritty material. So I srayed each out with electrical contact cleaner and put back in.

Prior to as mentioned above the motor was sluggish and had hesitation if i pumped the throttle sitting in neutral. Well now no hesitation and rersponds strong to throttle in neutral. Ran out of daylight yesterday, so this morning after some cleaning I'm going to take it for another trial run. If all is well, I will then run it to where some Hydroplane racing is being held. Wish me luck, and thanks for the injector tips, hopefully you helped solve the problem no doubt residual form my previous fuel issues of last season.
