I have a 96 M/C Maristar 225 with the corvette engine and it is overheating consistently.
I have changed the top thermostat and the impeller and still have the problem.
I cannot find an owners manual or anyone local who can help.

Have you checked the tranny cooler for obstructions? And have you checked the water pump?

I have a 95 225 with the vette LT1, My dealer also replaced a lower thermostat ( 2 thermostats ) on my motor. It was sticking and throwing overheat codes to the ECM. I have no ide where this thermostat is located, serching for a PDF to see I can find what he swapped. You have hit the main issues, now like billr said, water pump, strainer, obstructions, mysterious other thermostat.

Good luck

I have a 1996 190 w/ the vette LT1 also, I agree the the two previous posters, especially the checking of the tranny cooler.
