I'm new to the boating world. i'm looking at a boat that has an E-TEC 25 on it. It is a 2010 tiller model. The seller says that the engine was run with bad gas, so I'm assuming there is a start/stall issue or rough running. I thought it was carbureted, but it looks like it is fuel injected. The boat is at a good price, and I would like to fix it myself or with minimal cost. I just don't want to get stuck with a heavy repair bill. I was planning on checking compression. What are your thoughts? Are these engines costly to repair?
