I have a 1995 Sundancer 330 with V drives that I noticed yesterday has red fluid in the bilge water. I could not see anything obvious from top side and fluids look full. Any common issues for leaks I should start with?
 
Red fluid I suspect is transmission fluid. Check your V drives and if they are OK wedge yourself under the hatch and check the level of your trim tab pump, that has the same fluid in it.

Have someone work the tabs up and down and look for leaks. The pump is on the rear wall of the engine room right above the rear lower bilge sump, so that would be my first guess on where that fluid is coming from.
 
Check that the transmission dip sticks are screwed in fully. Unlike your engine they need to be screwed in and the transmission operates under pressure. So if they are not tight, oil is pushed out the dipsticks.
 
If you have zf marine transmissions it could be leaking from the top cap where the filter is,
it may not be installed properly. 6mm allen socket or wrench.
