6 cylinder chevy

[mrobertson]

Hey guys -

wellcraft newb here. I am looking at a late 70's 20 steplift. The boat originally had a mercruiser 470 4 cylinder in it with a mercruiser outdrive.

Right now it has a 6 cylinder 250 ci chevrolet in it. The outdrive is the original, but rebuilt.

My question, is the chevy a good engine, is it a common swap? Are parts cheap for it?

Any comments would be greatly appreciated
