Hey Gents,
I am the proud papa of an 86 Searay Pachanga II with a 5.7L Merc/Alpha One. Recently I removed the can system (my step father did this on his Pachanga with no issues, and other people have as well). I replaced the cans with a 90* 4" mandrel bent exhaust tube. Fits great. But thats not the problem. (I hope)
The problem is, now it suddenly wont idle. The idle with the cans was low to begin with (500ish) so I raised the idle to the standard 650-700rpms as per the owners manual. The engine has trouble starting and I must give it gas, even if its warmed up. Then it will stumble and stutter until I pump the throttle once or twice. At this point it will idle all darn day, when given the juice it will jump up through the RPM range with no issues at all. If I shut it down and try again, same same. I recently purchased the boat, and the owner did not provide with service records. The boat ran flawlessly on the water, easily hitting max rpms (and a speedo reading of 59mph) Would the muffling system cause all this issue? I have seen others run without it, but there is not a whole heck of a lot of Pachanga info floating around on the intraweb. Please someone help!! Oh, for the most part I am a DIYer, and dont have any issues, however, I dont have a lot of carb experience. I will be pulling the plugs to see how bad they look in a few.
