I've found a used boat that is exactly what I want, but it has a 2003 Yamaha 250 HPDI on it (very low hours since it was installed on this 2005 model boat as a leftover new engine.) I've searched this forum for HPDI issues and there sure are a lot of 'em! I'm about to be scared off this perfect boat. Are my fears of the engine justified? Does anyone have anything good to say about the HPDI, especially the early models? Appreciate your input.
