Thanks Mike,
After spending the day making templates for battery bank and the motor, I am back to the idea of using an extension to the shaft. It looks like an 8" prop shaft extension is going to be just right. I needed to move the battery bank forward to get the clearance for the battery bank at the aft end of the cockpit. Of course, I will give you the precise details when I have them.
Thanks,
Michael Ruiz

That is a comprehensive spreadsheet you have built for the boat. Some things to add to your spreadsheet for the motor might include:
* Likely the propeller is less than adequate if it was from an A4. Look for a 3 blade 12X9 and have the system programed for that prop
* USCG Master Switch for battery pack $50
* Heat sink for the Sevcon $50 (give it lots of ventilation)
* T Fuse to protect the 48v system mounted within 12inches of the batteries $100
* Coupler (likely different sized shafts) $100
* Adjustable motor mounts for alignment (minimum of 2) $100
* Battery monitor (I like the Sevcon) $350
* Control wiring for monitor with marine connectors $50
* Should go with 1/0 marine battery cables $150
* Rubber caps for protection for all power cable ends $20
* 48v15a charger would be appropriate for that battery pack $350
There are issues with running the small Honda in the lazerette. You need to provide for air cooling and exhausting. Make sure it is sealed so that exhaust does not fill into the living compartments. Do not store gas in the same compartment. The CG does not like the fuel arrangement and carburetor of the Honda generator so also have a plan for a deck tie down mounting of the Honda.
The Pearson sure are pretty boats.
