The front motor is not lower than the rear motor. They are at the same height. The front of each engine is lower than the rear. They look like a 60's musclecar with leaf spring shackles.:drink:

Is the motor height difference from front to back due to driveshaft angle and as a result when sitting idle in water or underway, the engine will theoretically be more level??

Can you show us the lower side of the dyno sheet
from 1,500 rpm's to 5,000 ?


Thanks
Jon


Ive never heard of anybody pulling one down below 2500-3000,especially a blower motor,I don't think it will ever see that kind of load in a boat.

Eddie,
Please tell Bruce hello. I hope he is well. Matt Beddoe


Maybe at speed the boat runs nose up leveling the motors out?

I know on drive shafts they dont want more than 5 degrees angle for the joints,that was for cars.

I'll bet with those motors down so low in that vee, that the CG is awesome. It is really looking good too. Your customer has to be pretty proud. I cannot wait to see the kind of numbers that vee lays down. You gotta know I love the orange too:drink:

Young Performance 12-11-2008 08:01 PM

The customer hasn't seen it yet:drink:
I'm really not sure about the engine angle. There are several theories, I'm just not sure which one they were going for.
Thanks everyone for the kind words, Eddie.

I rode in a similar 39 Skater V w/ JT. It had 1200 MRD's and was smooth as glass at 135 MPH... and was still pulling ---- we just were running out of water quickly!!!!! Don't know exactly how fast it was (it's been "re-rigged" since), but 135 MPH wasn't even close ------ nor close to the boat's ability.... still a bunch of hull left at that speed.

Thats awesome! I would bet 150 is pretty doable.

Eddie, do you have any good pics of the bottom, and/or a pic of the step(s). I have not looked at one of these Skaters up close. Just curious to see what it looks like.

And then take some pictures of the crank laying on the floor. :evilb::evilb:
