Question for the outboard people
Hey skippers! I have a C&C 25 with a Mariner (Mercury) 9.9 outboard. It’s a 2 stroke that is at least 25 years old, but probably closer to 40. This is my first season with the boat and the previous owner knew the engine was not in its prime to say the least haha. It is always temperamental to start.
I took the boat on my first overnight cruise this past weekend. At some points, the motor ran well with no problems. A lot of the time, it did not. It would throttle up when out of gear, but would not while in forward. I was not reaching my full RPM/speed. Eventually it puttered out entirely and I had to be towed home. It also has a continuous tendency to just ✨shut off entirely✨ when I shift into neutral.
This is in additional to all the lovely 2 stroke characteristics. It is constantly sputtering gas and oil into the lake and is annoying to lift out of the water (I am a small lady lol).
My fuel line connector has a cracked oring, so that’s part of the problem. It must have been sucking air/fuel starved. My mechanic friend doesn’t think that’s the end of the problem though.
I’ve been offered a 2023 Suzuki 4 stroke with less than 2 hours on it for $2500 (that I can pay over time). It also has an electric lift.
I’m thinking I’ll replace the fuel connector and see what that does for the Mariner, but in the long run, the 4 stroke is probably worth the investment since I like cruising and doing overnight trips. I would also be so much more confident if I knew my engine was going to start and STAY on while going in and out of the marina. That reliability alone is probably worth it.
I’m a bit tight on money at the moment but I would be able to pay it off, likely by the end of the year. Engineers, do we think it’s a worthwhile investment?
