Now I'm getting serious....

Looks great George, nice to see the TR in the water! After all you have done, a couple of bugs are to be expected, congrats again.

George, each time it is getting better.

Try to get the oil temp up. 180 is a good place to start.

My 454 running at 4,000 + for a bit sees 260 on the oil temp.

Oil should get to 180 or so to evaporated any condensate.

Thanks Ken.
Since the oil cooler is so large (3" X 15"), I'm likely to need an oil thermostat.
But before I make that decision, I need to run it long enough to let it build
some heat.
This was a pretty quick trip.

You have a very special build there Mr. Carter. Congrats!

Remind me what you ended up doing under the bow area again? Also, you may want to borrow a Mercury Rev4 prop to try. I suspect it would work very well.

Raw water pressure was 4 PSI @ 50 MPH
(the relief valve is set for 20 PSI) and it will rise at higher speeds.

Looks great George! I'm guessing your relief valve is "before" the raw water pump...and at 4psi at 50mph I am assuming you have the gauge reading "after" the raw water pump? Curious, because Merc had the sensor in my 496HO installed before the raw water pump and with the BH drive I blew my 35psi gauge. With the 502, I've installed the sensor in the same spot so I'm installing a relief valve this time, because it's $115 + shipping to get Livorsi to make a matching yellow gauge.

Glen, the pathway is:
Transom pickup, strainer, oil cooler, steering cooler, relief valve, raw water pump.
The pressure gauge is a mechanical gauge fed by a capillary plumbed
into the oil cooler drain. It seems to work well there.
You can see the relief valve in some of the pictures concerning changing
belts/crossover, etc on the previous page.
I blew the shaft seal out of the first pump by closing the ball valve on the
raw water inlet and running on the hose.
After reading your post again, I think the main difference is the shape of
the transom pickup I'm using, instead of the drive pickup.

An oil thermostat is a welcomed addition and will solve any over cooling of your oil.

George, are you not concerned about the water pressure? 4psi at 50mph before the pump? That just seems incredibly low to me.
With the bravo, I would have been around 25~30psi at 50mph

Glen, I'm using this 1" Stainless Marine pickup. It has little "angle incidence" in relation to the water flow.
The angle on the bottom can be ground on to reduce pressure if need be.

After running the boat several times, I had a slight fuel pressure problem. The large Holley Black Pro fuel pump provided just a bit too much fuel at idle for the matching dead head regulator (Holley 12-704) to manage, so the pressure would creep up to 7-8 PSI.
After conferring w/a Holley technician, I picked a Holley 12-841 bypass regulator. This required a bit of work. Part of the additional work was because when I was rigging the fuel system before I installed the remote heat exchanger, I didn't foresee the difficulty in removing the fuel pump at a later date. I took this opportunity to relocate the Holley fuel pump.
It took part of two days to get the pump out. One screw came out easily, the other was much more difficult and required a couple of extra elbows in my right arm.





I built another pump/regulator mounting bracket from some scrap StarBoard. Don't know why, but it took me about three tries to get this right. In the rest of the pictures, you can see the rest of the installation. I installed Packard connectors for the pump and the pressure gauge sender. Also the regulator bypass line is visible returning to the fuel tank.
The good news is the pressure is dead steady at about 4-1/2 PSI.

George have you put a Merc Rev4 prop on your boat yet to try? I think that it will prove to be amazing.

The Rev4 works well with deep drives and I believe you said that your measurement showed the prop shaft centerline to be exactly 6" below the keel. Try it, you'll like it. They run just a touch stiff to stamped pitch.

Thank you Greg.
I'll try to find one to try.

[JParanee]

This thread is incredible

thank you George for documenting all of this !!

[yeller]

How's the boat George? Did you get all the bugs worked out?

Glen,
Bugs are mostly gone. Waiting for a new speedo, need to change fuel pressure
and oil temp senders.
But the worst problem is fixing a spot in the gel on the foredeck. And now I
have to wait on days over 70* to work on it.
You and Bobbi come see us!

Super Duper cool job Mr Carter!!! U are somethin special
question about the oil cooler,,, i got the 3x18 dual cooler from Revolution marine. Do you think a thermostat will be necessary??? Could the oil really run to cool??? The oil filter right now without a cooler is hott. Like it will burn your hand hott when I run the boat. What do u guyz think. Can't wait to remove the winter cover an get started on many improvements an maintenance work
