I picked up an old Baja as a project boat that has a carb version 572 engine. I need to find out more about the engine, if parts are available, specs for rebuild etc. I would also like to know if there is any amount of "beef" you can do to a Bravo 1 outdrive to hold this engine...I'm being told it may not be possible.

hmmmmm,,thought 540 was the biggest N/A engine they built..are you sure it wasnt a sc engine at one time and they took the blower off?

I will talk to a friend with them in a 41 Chris craft. I know that He runs the boat once every 2 or 3 years an blows a eng. Try to tell Him old fuel blown eng. He dont use this boat. 20 years 20 hours. It has #5 drivers. What a wast. Artie

That I don't know...it seems to be the only info I can find is that it may have been an early 800SC...regardless, I'm going to yank it and go through it..

Get one of these, they usually can be found on ebay.

I'm pretty sure the 800sc was 572 cubic inches. Merc also made a 575 hp carbed 540 bulldog back in the late 80's.
