Dave:
Since you're getting low voltage between the batt terminal and the
alternator casing, it does sound irrefutable, it's kicking the bucket.
You can remove your alternator and take it to an auto-electric shop. New
electronic module and bearings and you have a good as new rebuilt
alternator.
You may want to replace the lift pump.anyway and use the electric pump as
backup and for bleeding.

I recently had a similar issue where the engine would drop RPM's under load
and eventaully stumble and die. It ended up being the fuel lift pump was on
it's last legs and just not getting enough fuel to the high pressure pump
once the fuel level in the tank was low enough not to just siphon.
Maybe group in the pickup tube? Try disconnecting it and blowing it outBill ColemanOn Aug 17, 2019 8:13 PM, Eugene Fodor via CnC-List wrote:My 2GMF 13HP on my 29 mk 2 is dropping RPMs at max throttle under load. It also appears to drift a bit while operating at a fixed throttle. Tied at the dock
