Hello my name is ***** ***** am I speaking with?
This is a pretty old engine. When was the last time it ran correctly?
Have you done any kind of troubleshooting yourself yet, such as compression and spark output testing?
How old is the fuel?
Customer: replied 2 years ago.
I've been fishing 3 times this spring, we have had a lot of rain in Texas, the boat preformed just fine, I added sea foam before I went out on the last run . Haven't done any checking yet, the gas is about a month old, I run the engine once a month when sitting over the winter.

Have you run the engine off of another fuel source yet? There is some troubleshooting that needs to be done here. What kinds of questions did you have about it?
Customer: replied 2 years ago.
No haven't had time, will dig into more when I'm off of work, which will start Sunday. The engine Idles just fine, will run all day, manual throttle will increase rpm, no problem, just when I try to put it in gear.
