This winter I had all my injectors replaced and when back in the water, it took some effort to get the port engine started. I primed and re-primed before she finally fired up.
During the priming process with the manual plunger, I noticed a small amount of fuel leaking in and around the plunger. I made a note to "self", I needed to spend more time with this unit and research the possibility of having to repair/replace/overhaul this primer pump.
Well, yesterday was the first day cruising since my return to the water and at the onset, both engines started right up and ran great.
Then about an hour of cruising, I noticed what seemed to be a degradation of power along with some minor vibration. After some trouble shooting, I determined the culprit was the port engine. Hmmmm..
I ran at a slower RPM with no vibration for about an hour then throttled back up to normal RPM. All seemed good but whether it was my mind playing tricks or there was actually some vibration, but either way, it seemed to be working okay.
We spent a lovely night on the hook here on the Gulf Coast but this morning when I went to start the "girls" up, the port engine balked. I am NOT one to spend time turning and turning over these engines, so a trip to the engine room was in order.
I once again focused on the manual primer plunger and it was soft with no resistance. Another "aha moment".
After several pumps, she firmed up and another attempt to start was made. She started without hesitation.
Okay... after all this information,.. the question is...
Is this situation connected? Did I somehow introduce air into the fuel system with a less than perfectly airtight primer pump? Could this be the culprit of my engine running rough?
Or could this be an issue with contaminated fuel?
Thanks for taking the time to read this. I will hang up and listen.
Everyone stay safe. Wash those hands
