Sounds like a lot of fun. Looking forward to this...

What boxes are you running. If they are the mercury adjustable boxes I would start with the drives 1" below the bottom with the boxes in the center hole. That way you can adjust up or down and inch. The 38 KV I raced back in the day liked the drives an inch above the bottom but is was super light.

HI Heath, boy you really ripped her apart going to be brand new ,the flat decks are worth redoing such nice lines on them . CIG 3 yes they are the Mercury adjustable boxes , I had a similar thread few months ago about x dimension on the kv with #3's . Team Archer (Dan) chimed in and suggested 3" below and 17.5"-18" prop since the bow is heavier . I have spacers that I got with the drives so I think I am going to set the "x" 3 below with 1" spacer installed and the gimble on bottom hole of the boxes so I can pull spacer out and move gimble up when I test props . Thanks for the input .

Mark are you running number Vs or IIIs ? the number Vs can run a lot higher than the IIIs We are running a 79 Larry Smith with VIs at 1 inch above the bottom with the number Vs on boxes I would start at 1 inch above the bottom at neutral on the boxes witch allows you to move up or down. If you have any questions feel free to give me a call. Regards Dan

Thanks Dan for letting me pick your brain on the drive set up .

Have you set your boat up with your number V's yet? The set up, I'm about to install is very similar to yours, other than I have a notched transom. If you set it up 1" above the transom, I'm curious how it worked for you.

Rigging transom this winter i will post pics of my work

Were/are you running intercoolers on your blower set-up? I received my engines last week and I'm having doubts they will fit under the races hatches. I had planned on raising the X 3", in order to get the prop shaft 1" above the bottom, but now I'm just hoping I can get the race hatches closed with the engines at the stock location. With the adjustable boxes I should be able to get the shafts 1" below the hull, which won't be ideal, but at this point, it is what it is.

Just rebuild your dog houses taller nd no one will no the difference.

I was thinking about doing that. Ha, I'll add that to the list of projects.

What else are you going to do this winter

Entire cabin is getting redone, replacing the transom, and then if there is time, prep the boat for Glass Dave to paint. This may be a two year project before it hits the water. I'm curious to see what crazy canucks boat likes, as it's a fairly similar set up.

Hey Dan, my drives are even with the bottom with a spacer on them. Did you guys ever do any testing without the spacers or do you figure it was well sorted out long before it made it's way out to you?

I believe that the boat was set up for the Catalina Ski Race. That's why it has the spacer in the drive to keep the rooster tail down and to get on plane faster. I don't remember that was a long time ago and we were still racing back then and testing 2 to 3 boats a week.

Have a set of 2" spacers and studs if you need some

Thanks, makes sense. The guy that owned it back then changed his email address and that was all I ever had to contact him.

His name was Jody Martin. the last time I worked on that boat was 2004. Looked back old invoices we never played with drive spacers just trying to get motors running good.
