Thanks to all who gave me advice about my recently cracked block on my 5.7L Merc (210hp). As I expected, the repair shop is not stepping up to take any responsibility, so I'm going to have to get the work done elsewhere and sue. What a waste of time and energy.....

So, the estimate I got to repair the motor is about $7000 ($3000 for the block, and the rest in parts and labor). I recently came across a posting for a 2006 Mercr 350hp 5.7L BRAVO carborated engine that is around $5500. I was thinking that I could swap out the 210hp entirely rather than repair the block, but I was told that putting in a Bravo may require changing the Alpha outdrive on my setup (torque and controls/instruments compatability issues) and may involve lots of other labor and parts costs that could push the total cost up towards $10,000 (including the $5500 motor). Does anyone know whether that sounds right? I was hoping that I could simply have them pull out the existing motor (4 hours?) and then drop in the new motor (4 hours?) and hook up any additional small items (4hours?) for about 10-15 hours total.

As usual, I searched other posts for this information, but couldn't find anything. If anyone can give me any advice on this or knows whether this has been answered elsewhere, please let me know. Thanks again iBoat members!

Switching to a Bravo is not going to be cheap.

The Alphas are good for up to about 300 hp. I think your money would be better spent on an engine that was under that power level. Check out RapidO marine in FL.

I'm not sure if you actually need to swap from your alpha to a bravo.

The engine is the same for both Alpha and Bravo drives. The only difference is the ignition modules, and shift interrupt switch setup is needed for the Alpha drives.

$7000 is too much.....
You can get a brand new base engine from ebasic for 2700, & switch over all of your peripherals......;)
