me thinks that AA impeller is a might big for your engine. You got a 455 olds in it right?
I just had to share my progress on my new jet... It's been in the boat for months but I had no time to finish all the details. I was working on it an hour at a time until this weekend.
It's a blueprinted Aggressor 9-vane bowl, w/ bronze AA imp., droop, hyd. place diverter etc... a huge upgrade from the old hat that was in it.
What kind of increase do you'll think I'll see as is, w/o a ride plate and loader, from a tired stock JC?
The only thing now is to install the diverter switch from Rex Marine... it's been two months since ordering, and I settled to jerry-rig one they have in stock.

That's exactly what I thought... it was toned down to something between and A and AA. I'm kinda going along w/ Squitin' Thunder's idea on the impeller issue. The motor was rebult and estimates have it in the 430 horespower range. Whata think?
Your engine (455) will live much longer with the bigger impeller, meaning you can run it harder and longer than you would be able to with something less than an A impeller. Just take care of the motor, no five mile WOT blasts
Looks great! Now go have some fun Sleek
I think the Olds will get along great with that impeller. Should keep it away from those high Rs that will kill it.
My olds would damn near pull tree stumps, I think the A/AA might be good. 455s do not like running long periods WOT.

Nice Ride 455.might Want To Take Alook Over In Gearhead Section @ The 455 Oil Return Mods. There's A Good Thread(i Can't Link)about A Cheap Modification Of Putting Oil Return Hose From The Back Of The Heads Down To The Pan Or Valley. Every Olds I've Seen Come Apart Was Oiling Problem Related.looks Like The Hose Mods Would Fix This Shortcoming.keep The Pics Comin!

Boy do I know all about the 455 problems guys! The first season I was seeing what it could do and I ended up w/ oil pouring out the oil fill, PCV valve and valve covers. I thought, well that didn't last long... i figured I'd get one season before an eng. overhaul.
So I've learned my lesson, and no more WOT passes... for very long... and I had a knowlegeable boat engine builder build it to last (knock on wood) w/ restrictors, a custom Gale Banks 10 qt. oil pan, semi-hot Engle cam etc...
I'm lovin it...
Is that hull a Nordic? If so, got any pics?
