Great looking motor. What is the HP and drive ratio for the Velvet drive.
Have you decided on a prop.
What sort of RPM will the motor turn

Thanks, Guys!!

The engine is 330 hp and preferred WOT is 5200 rpm. The Velvet Drive is the New Liberty A (replaced the old 5000A) 8 deg down angle and has a 1:1 gear ratio. I am starting out with a 13 X 13 full cup OJ three blade prop. What you see in front of you, including a wiring harness, a fuel pre-filter, shipping to the distributor from Crusader, and WI sales tax was $16,467.13. This is a very completed package. I only need to hook up the water intake system to the engine oil heat exchanger, the exhaust system, and what ever gauge and controls I prefer. The price may seem high, but after researching what is out there and what needed to be added to other so called "deals" to come up to this level of completeness, I think the package was well worth it. And I know what I have.

Crusader has long been power of choice in Sportfish offshore yachts. That is quite a torque monster you got there.

Roberta .Your drive is the same ratio that mine is in my 66 Century Resorter. The prop is the same size as the one I lost coming in to our dock a couple of years agoand never found. Any way I got 50 MPH out of that prop and trans in a boat that weight,s about 2800lbs witha full tank of gas. It was just me and not a full tanks of gas.
This year and part of last I refinished the sides with new stain and 12 coarts of varnish. Removed the covering boards and front decking and replasce with all new seplee. Stained and 15 coats of varnish.

Y'know, since you got a full system closed cooling, you can plumbing tap into that, and have yourself cockpit heat.
Just like heat in your car !!!

How exciting, Roberta! I love seeing your beautiful smiling face in one of the photos too and it gives perspective to the size of that monster!

Thanks Riff. Thanks Gayle!!!

Today I'm spending some time sizing up that Big Blue and figuring out where it will ultimately reside in the Torpedo. Accessing the output shaft will be a bit of a challenge as it is under the back of the transmission. I will no doubt be lying along side the engine to get to the four bolts. There is room under the stringers to reach in, but I will need to plan the plumbing to make sure I don't paint myself into a corner. These are the things where planning will hopefully help avoid traps.

Once the motor is set things will move rather quickly as I have been doing a lot of work on the deck battens and interior. Just haven't been able to put any of it in permanently and get on with the decking.

I wonder if there is such a thing as a nutplate ring for the output flange bolts.
That could make life easier.

I think the diameter of the hub on the flange would prevent all four bolt holes from being covered, but it would get three. I'll be standing on my head later this month getting those buggers in. :lol: :lol: :lol: :lol:
