I have a 1992 Catilina Spa with Acura System plumbing. A steady leak developed at the pump and motor junction. Before I tackle a pump/motor disassembly project, is there anything that may be a simple fix (e.g., tighen up, etc) I should try first?

I hope my post doesn't come too late. As soon as that junction starts leaking, you need to tackle that immediately! What will ultimately happen is your front bearing will go out on the motor, due to water intrusion, and the motor shaft going into the pump will rust and swell, making not only the disassembly nearly impossible, but it will split your plastic impeller in the pump. A simple seal kit, usually under 15 bucks, will solve this problem. What you would do is remove the screws around the pump face, and separate the 2 halves of the pump. You will see the impeller immediately... it looks like a mini turbine. On the back side of the motor, there is often a small cover that you can remove. There is usually a slot in the back of the shaft to put a screwdriver in there to keep the shaft from turning while you twist the impeller counter clockwise to remove it from the motor shaft. If you don't have this slot, you can often snuggle a channel lock plier between the motor and the pump and grip the shaft that way, but be careful not to crush the impeller part in the process. Once you get the impeller out, you will see the seal immediately. The impeller will spin off fairly easily, unless your shaft has started to rust.

now here is a silly, and often successful way to "re-seal" your seal. I've done this accidentally once, and it worked so well that I do it first anytime I have a leaky seal, and so far it's worked every time. Drain the water from the pump, start the motor dry, yes, DRY. After a few seconds you should start to hear the seal start to scream in pain, and when that happens, immediately shut the motor off and fill er up! What that does is burn off any cracks in the seal and it magically seems to work!
