3100 Water Tank Replacement

[a1a82246]

Hello- I have a 1993 Tiara 31. Unfortunately the poly water tank is leaking due to a long fracture along the top edge (on the hull side), so repair is out of the question. It looks like the tank will have to be replaced . I hopefully can do it without removing the starboard engine (Crusader 454's). It looks like it may be doable if I remove the manifold, riser and exhaust hose and drop the heat exchanger and oil cooler. Has anybody done this?
Thank you, Keith
