Welcome to the Diesel Stop
The 7.3 IDI is NOT going to fit in place of the 5.7 mercruiser.
First off the mercruiser is the same thing as a small block chevy 350 and the IDI is like a big block 444. Besides the manifolds and flywheels being way different, there is the issue of weight.
The Merc weighs in at about 850 Lbs. The IDI is about 950 Lbs. 100 lbs may not seem like much, but in the back end of a boat, it may make the transom sink too low and take on water.
