Location: Annapolis, MD
Boat: 2006 Tahoe 215 I/O
Engine: V6 Mercruiser 4.3l TKS
Serial: OW344165
Hey guys, I've found some good info on this forum that's somewhat related to the problem I'm having, but no "ahah" moment yet.
Symptoms:
When cold, starts up like a dream (we're talking 1st/2nd crank) with no throttle needed, runs smooth for a few minutes, and then drops RPMs and stalls.
After initial start and stall it then requires throttle, and often a good bit of cranking, to start. It then requires gradually more throttle to keep from stalling as it continues to warm up.
Setup:
On land, using muffs.
For fuel, using a regular 5-gallon gas can with a fuel line running to the filter / water separator. Is this acceptable?
I don't think the boat's fuel tank is pressurized, or any other magic is happening in the tank, but it wouldn't be the first time I was wrong.
Observation:
TKS module doesn't "hiss" after startup.
Engine stays at operating temp of 160 (under throttle of course), but exhaust seems hotter than normal despite verification that manifolds and elbows are getting good water flow.
Exhaust actually feels somewhat normal while running, but heats up a lot after shutting it down.
Wondering if the TKS module is leanning out the mixture as the boat warms up? I've got the CA emissions setup, so the idle mixture screw has a cap over it. As such, I don't want to mess with that (unless all other possibilities are ruled out) because it's probably set correctly.
Thanks in advance for your help!
