I know everyone.....and I mean everyone, has a big block something or other in their jet boat. I was cruising through the internet and saw a nifty little 18 with a small block that had a blower on it. It seemed priced the same as if it had a big block in it, but I can't see why this wouldn't be better than a big block (lighter, more RPM, and cheaper to work on). Am I wrong? What are the drawbacks/advantages to a small block w/blower. Thanks in advance for the info.
