As with any boat purchase get a good marine surveyor, ideally one who knows Tiara’s and a good engine tech to check out the mechanicals. The QSM-11 is a very good engine if run and maintained properly. It has a dry exhaust manifold that can warp if the engine is run hard and or overloaded/over-propped. Most engine techs familiar with Cummins know this and will have that as one of the things to check.
The 42 is a great boat. I looked to buy one last summer but couldn’t find anything decent. Hope it works out for you.
