You can find new 3.0l all day long. Mercruiser still packages new for new boats but it is a 135hp now. Not sure who you talked to.

Ok guys.... We did it. 12 hours of scrubbing + trying to figure out how to put it back together, we made it happen:

Couple things still to do: 1) adjust the choke so it moves more freely. Right now it's a little sticky. 2) find a spring for the fuel filter. Ours didn't have one.

Also, this was a weird carburetor. There was no place for a check ball under the accelerator pump, nor was this model # listed. 705, according to rochester, means this was a quad-barrel jet. Well that's just not right!

We'll see how it runs when we get it back on the engine!

Next step is removing 2 intake valve springs to clean some surface rust off the intake manifold -.-

The project marches on!
