It's a 1989 model year.

I have a hint that is not 90 because tha manual shows a bit diffrent from what I have. Thank`s a ton . I hope the water pump will fit. The exploded view shows very close with my old parts. If not I will use it as is . Impeller still good pumping strong ,the only thing that is not right the textolit washers inside the pump are gone and the drive shaft seal above the pump is weak and the pump is leaking ( I put some orings) ,but still have a healty water jet at discharge port on the thermostat housing.All the best Alex
