Having read the "Seafoam" treatment articles I tried this. On Sunday we had a spat of endless showers/sun, on again and off. She would fire, run, stall, not fire, wait, prime, fire, run a few seconds stall etc; So I disconnected the fuel line and directly added the Seafoam into the fuel line. I squeezed the prime bulb until I heard the fuel in the carbs as best i could tell. I let it sit 30 minutes +/-. I went through starting her again, on the water ears, she fired, sputtered, ran, plume of dark smoke, ran better, better, and better, settle down easily idling at 8-900 rpm's. Ran for awhile, shut her down with rain coming again. Tried again Monday. Pushed key in to a count of five, and with key in turned to start she jumped alive while cold though I did prime a bit until idling which came up quick. Restarted like a charm. This was just on the regular gas. Did it again Wednesday. So come this weekend if the monsoons abate were headed out to Inner Schoodic Ridge. Tell the cod and halibut were coming to kick butt. So would a couple of teaspoons of Seafoam make me run better? Just kidding Gary

Good deal - sounds like she's ready for action! Just temember, DO NOT start the engine dry without the muffs or in water. 10 seconds of dry running can damage the water pump impeller - 30 seconds can destroy it. :evil:
I've heard of guys running motors dry for a couple minutes dry with no damage - that's what they thought - but I bet they did not tear into the water pump and look at the impeller. My bet - the edges were glossy and hard - that's what dry spinning does. It also overheats the plastic pump housing and can distort it. Either way, you have an impeller or water pump with a limited life. And the engine does not like to run long without a good cooling water supply!! :wink:
I even carry a spare impeller on the boat. I think I could replace it if I absolutely had to on the water, but I sure hope I never have to! I think SeaTow would be before that. :roll:
