Gents,
Considering upgrading to a 25' Grady. Most of these boats came through with 225's and a few T/150's. I've seen a few 01's & 02's with the 250. General consensus is that with twin anything they're going to be gas hogs and I think I'll eliminate those. Although I have a single 150 now that runs great. I've read a couple 100 pages of posts on here and the 225's are a little prone to blowing up. Oil injection failed or overheated seems to be the cause. I don't understand how they run on 4-cyls when idling. How are the other 2 cyls lubricated? Is the system that controls this complicated? Why is it used? Sensor and plug fouling? I thought these injection pumps leaned the oil to 100:1 at idle. I know nothing about the 250. Was that a white elephant or what? Is this a HPDI in the 2001 vintage? Can these big motors give me the same reliability that I get with my 150? Opinions and facts welcome.
Thanks Guys!!
