Thanks for the welcome. I am on many car forums as well as Salt water fish forums but this is my first boat forum. So there is no possibility of boring a 2.5 and using the 3.0 crank and pistons. The engine that was in the boat was not winterized and cracked. It is in a 99 Mirada. Also I was curious on more info on Miradas as I can't seem to find any.
If I'm not mistaken, all the 3.0 liter blocks are the same - just be sure to transfer the "stuff" from your current engine to the new block and you should be fine.
Is there a place I can look to find out what years had what blocks and if they changed them from year to year? I found a good deal on a longblock from a 94 searay and my boat is a 99 Marada If that motor would work I could pick it up for a good price and be up and running in no time.
Ok so i could just take the flywheel off the motor in my boat and be ok. I figured that but wasn't sure if they had made any changes to the crank. But from what I am finding in my research they are all the same.
