Title: 92 21' Ultra
Post by: Ultra460 on May 07, 2009, 08:47:50 PM

So I figured I would start my own project thread. There has already been a lot of projects completed but the list never seems to end. The most recent project was the pump. I knew the old "B" impellor had seen better days and it was leaking a decent amount of water at the packing gland also. After talking with Tom @ JBP the pump was pulled and shipped to him. He did a full rebuild, installed a new alluminum "A" impellor and a new 17-4 shaft. He also stripped and repainted the pump and made some new aluminum transom adapters too.

After hours of scrapping silicone off the transom and a little polish work on the bell housing.

Fresh pump awaiting install.

Sand blasted and repainted the pump brace while I was waiting to get the pump back.

I also sent Tom my transom adapters so he could make me some new ones out of aluminum.
Old adapters. :mad:

New adapters after a little polishing.

Pump all bolted in

New transom adapters in place. Looks much better! ;D

The finished product with the HPH and Place diverter I purchased from JBP last year. Set the ride plate to 2 1/2 degrees up. Ready to roll.

The boat GPS'd 54 mph @4900rpm with the old pump set up and with the new pump set up it GPS'd 57.5 mph @4750. It dosen't cavitate at all and gets out of the hole way better than it ever did with the old pump. A big thanks to Tom and his crew at JBP for all the hard work.

Next on the never ending list of projects is a set of Anodized Black billet swimsteps to match the rest of the billet on the boat. Like these. http://danamarineproducts.com/ProductDetails.cfm?group_id=2&catid=17&productid=4319&CFID=615914&CFTOKEN=4a53542-4a17f8ee-fdd8-47a2-ae13-b90f907c2be6

Then I would like to find some center rise manifolds to replace the current logs. Or maybe some lightning water jacketed headers would be nice also $$$. ::) And the list goes on and on... :banghead:

I know, I know. I need to do some more polishing... :banghead:

Nice work on the pump, I really like those polished aluminum transom plates, it's a nice way to clean it up a bit. Those swim steps will look great too, they might get hot though being black and all.

Either way, clean boat and good work!

Yeah I thought about the black getting hot but all the other billet on the boat is black, so IDK. I'm still not 100% on those yet.

Thanks for the compliments.

I wouldn't worry about the steps being hot. Anyone willing to jump off a running boat deserves it anyway, IMO  >:D

J/k, good looking work, that's why Tommies the best! You did your part too, great looking ride! ;D
