Hell ya greg, as soon as this thing has a motor! And no more cracks lol. 

Just got word from the builder about my block, needless to say, it was terrible. Looking for a crank for my olds 455. Also some pistons/rods.

Here are the pics i took. The stringers are in pretty good shape, no flex, rotting, ext. They are not as hairline as i thought, every time i get under in look,they seem to look bigger  . I dont think they can be just gelcoat because there is oil comeing through the cracks...  well, maybe these will help..

1986 Ford 250 6.9 turbo. Just picked her up a few weeks ago. 108,000 original miles!!

Greg, im not trying to rebuild the pump, just wondering what is involved in removal of the entire pump from the hull. With that said, HOLY COW!! THANKS A TON for the other links. I printed out all the pages and put them in a folder with all my other paperwork on my boat. When the time comes to rebuild it (will be doing it myself for sure), i will have all the documents for reference. Those were great step by step instructions. Thanks again!

Tom, Thanks for the offer. I will be calling you soon with a question about the how to seal the intake to the hull. Thanks again. I am very glad i surfed across this site.

Hey all. I have never removed a pump out from my boat and since the motor is out for a rebuild, i was thinking now is the time. The pump is fine and has pretty new PC on it, but there is a leak somewhere and i figured now is the time to find it. I think its comeing from where the bowl through the transom adapter plate. There is a small bead of silicone around the bowl and you can see a few gaps. Even if this isnt the leak, i would like to take it out anyway so i can clean out the bilge and clean the intake of the pump. My question is what gaskets will i need to purchase and what needs to be re-siliconed after reinstallation. Also, What goes into removing the loader grate?

Hey, I am in the market for a set of whiteface guages. I saw a killer deal on here and PMed on them, just to re-read the post and see they were sold already  . So if anyone has a gauge set lying around and dont mind shipping to sacramento let me know!!

Looks like you got to have a lot of fun. Here's a good info type of site for Olds engines...

What are your plans for the engine? Rebuild? More HP?

I like the "snail protector". 

     Glad to see all the comments, i didnt get many on other boating sites. Thanks hotrod, i have been checking out 442.com and realoldspower.com for a while, they are LOADED with info on the 455. Great sites.
     As for the motor, it had a spun bearing when i purchased it. Constant problem with many olds motors from what i gather. I took it out on the lake anyway just to see how she ran anyway since i knew i was gonna rebuild anyhow. It did make for a good video though, you can hear it ticking in the background lol. I am haveing the bottom done, new bearings, lifters, adding oil restrictors, crank turn, resizeing rods, also new rings and ARP hardware. More agressive cam, getting heads decked and ported, new valves. Pretty much an overhaul, mild motor. When it was running, she did 60 at 4000rpm, plenty fast for now  .   Here is the video if you all want a good laugh   

     

Had a build thread on another forum, figured i would post here to see if i get more replies, the other site is a smaller forum. Here it is as it sits so far.

The boat is a 71' Tahiti clone of a Sidewinder. Its got an olds 455/berkley




Well, It has been in the upper 70's all week here in cali so i decided to pull off the cover and get busy on the boat. Decided to get the motor out so i could start up the "re-wire" on it, and boy does it need it! Looks like to monkeys played chinese jump rope with them. Figureing its going to be a month or so before i have the cash for the rebuild, i went down to my local Harbor Freight Tools and picked up a 1000lbs engine stand for a cool 39.99! I dont know if you canadians have them, but they are the best place to buy tools that you dont use to often. The quality isnt really the best, but if you only need to use the stuff every now and again, they have rock bottom prices. Well as far as pulling the motor, IT WAS A BREEZE. I had my father on the jack, and my girlfriend takeing pics and helping out as well. 25-30 minutes, not bad for pulling the motor out for the first time. Driveline looked pretty good, pump splines were in good shape, stringers looked solid, pretty good day so far. Then the gods aligned the stars in the shape of a pentagram and THIS happend. While pulling off the flywheel so i could mount the motor onto my stand, THE VERY LAST BOLT STIPPED!!!!!   . I ran out of options, so i drilled out the grade 8 bolt and hammerd in an "EZ-out" and i figured i was in good shape......until the EZ-out snaped inside the @#$% BOLT! bash. Well that was the end of the day, had to go cool off and think about my next step.. I guess im gonna use my plasma cutter and try to blast out what is left of the head and then go from there.......god, what a crappy way to end the day. But i did get some good pics
















To the victor goes the spoils!!!






And now the broken bolt
