Water in the fuel is what caused the power loss and scoring in the cylinders. Check the other 4 cylinders for scoring as wellSo a lot has happened in a very short time frame for me and poor Tranquilo.
First, I started having major power loss at WOT with my 2018 Suzuki 300 with only 180 hours. It took almost 2 months for Suzuki to identify that I have 2 scorn cylinders. My symptoms are likely the result of the variable valve timing adjusting to the poor compression. They then told me my warranty is no longer through suzuki but covered by an extended warranty company (Cornerstone United Inc.) I am currently in the process of filing a claim with them. Wish me luck.
Second, is an issue I knew I would be facing sooner than later and that is my 28 year old fuel tank. I started getting water in my fuel but no fuel smell. I found I was missing the loop in my breather hose so I assumed this was the culprit, then I failed a leak down test. Because my boat is more than likely in boat jail for the rest of the season I am more than likely going to bite the bullet and replace it. This is a pretty big task because the tank is glassed in below deck. I received a quote for 2200 for a new tank then 6,900 for the project. I plan on pulling the tank myself to save some money, then I’ll pay a pro to finish the job. Once again, wish me luck!
I’ll keep everyone posted on the progress.
I wish it were that simple. Unfortunately, my symptoms started long before water got in my fuel tank. Motor has perfect compression and physical exam of “scoring” revealed benign superficial scuffs that couldn’t even be felt with a fingernail. Also, power loss was replicated with a completely new fuel source. The problem looks to be electrical not mechanical. I’ll update soon.Water in the fuel is what caused the power loss and scoring in the cylinders. Check the other 4 cylinders for scoring as well
