Dear Harry,

It has been nearly six months since the new PSI surface drives have been installed and I felt it was time to let you know exactly how things are going and how pleased we are with our investment. 

Just to be clear, prior to the installation of the new PSI drives the previous outdrives were lasting 2 - 3 weeks. Each time we had a drive failure the rebuild cost was $1600 and the round trip shipping for the repair of the drives was another $500. If you add to it the maintenance time to install a drive, the opportunity costs of what the maintenance department could be accomplishing, the loss of customer revenue, and the customer dissatisfaction, the cost of each failure could easily be placed at $3500.

The ongoing drive failures also placed the Resort in a position of high potential liability for passengers, crew, and vessel should the outdrive failure occur during a key maneuver or during inclement weather.

To sum it up the ongoing outdrive failures we were experiencing were costing the Resort dearly in both direct and indirect costs.

Now, for the positive news: Since we have installed your PSI outdrives the boat has only been down for six hours that could be attributed directly to the drives. That is during nearly six months of operation. For a conservative estimate I feel we have saved nearly $26,000 in direct costs in the first six months.

Also, the installation of the PSI drives has benefited us in two very unexpected ways. First, during the first few months of 1999 the water levels for Lake Havasu were the lowest seen in nearly a decade. It would have been virtually impossible to operate the boat in the marina or channel during this time had the new drives not been installed, the 10" - 12" lesser draft made it possible. If the old drives were in operation the failure rate would have doubled because of the inevitable hits taken from the lake bottom. Secondly, we are absolutely amazed at the improvement in fuel economy since the installation. We are currently running two Star Power 7.3 Ford Diesels and the fuel consumption has dropped by nearly 18% over last year during the same months. An unexpected savings of over $600 a month.

The direct savings we have experienced since the installation of the PSI drives such as drive rebuilds, shipping, and fuel costs are easily calculated. However, the many other benefits such .as improved customer satisfaction, captain and crew confidence, and overall Resort morale may be even more important to consider as part of the equation. I truly believe that when everything is counted the new PSI drives have fully paid for themselves in the short six months we have had them in use.

Thanks again for working with us in our remote geographic location. The confidence your drives have restored to our operations is fantastic. I would be happy to speak to any prospective purchasers to relay our story.

Sincerely,

Scott V. Mathews General Manager
