"Hi to all,
I finally got my bellhousing issue taken care of. Motor was reinstalled and reconnected. Upper housing reinstalled etc, etc. I got it started this past saturday using the the waterhose and suction cup deal. My concern is once the engine started I got water blowing through the two outlet tubes on either side at the bottom of the transom plate. Is this correct until the thermostat opens? Once the engine gets up to operating temp and the thermostat opens does this water flow stop at the transom and come out the the exhaust ports above the prop? I'm used to 2 cycle outboards and 2 stroke jetski's. This outdrive thing is all new to me.

Thanks,
Kevin"
 
"The water will always flow fi

"The water will always flow first through the double bypass, as it is the easiest way out. This is why if you hook a garden hose to the outdrive grid you will see that most of the water comes through the double bypass. However, when the engine RPM increase, so does the water flow, and more water will flow through the outdrive exhaust outlet than at idle."
 
"That's what I'm seein

"That's what I'm seeing. I'm still going to take the exhaust risers off and give them a good cleaning. This used to be a saltwater boat.

As far as the charging circuit goes, after I run the engine with the hose and let it warm up and then shut it down the engine is very sluggish to turn over when I try to restart it. The gauge for the alternator appears to have ~13-13.5 volts to it but I will check it with a voltmeter in a day or so. I was thinking that the engine might be running off the battery and that the alternator is not putting out the current to run the engine and charge the battery. I noticed that the alternator (a 3 wire) has the alt. gnd cable and another that's pigtailed off of it. Does the pigtail go to engine gnd? A friend disconnected it when I pulled the engine and he can't remember. I was on the starter side disconnecting everything on that side."

"IF you have a 3-wire alternator, the wire your friend disconnected comes from the same circuit as the (+) of the coil, and that wire has a resistor installed. With that wire disconnected, the alternator will never charge, as it provides the field excitation the alternator needs to work."

"El,
I've got the wire with the resistor connected along with the ground and the red wire. Off of the ground wire is another ground wire. This is the ground wire I'm refering to.
