Disregard the 100 psi HP pump, its probably less but would be much more then 13

I also think good possibility of fuel pump pressure is a tad to high

OK you got an old one. Since its a repower then would need to know the year of the boat, because that would help get in the ball park. Being that old its a Gi, GSi or GLi because they are the only ones which list HP at 11 +/- 2 psi (9 to 13) GM makes the motor and Delphi makes the ECM. VP...

A primer bulb will not hurt and can help getting things started. Not knowing where things will be located, how it will be routed or what motor and boat, just a guess right now

It's real cheap to add a boat to the home owners policy to cover liability

The way to find out what your motor uses is with the serial number? We don't even know what year the motor is? Being a VST TBI, your pressure should be 30 psi and is measured using adapter 91-806901 Your low pressure pump is working seeing 6 psi, the HP pump is not The VST can be taken apart...

I reconnect the hoses after draining. I also leave all the plugs out and in the cup holder, but there is nothing wrong with reinstalling. If there left out and there happens to be some water behind a mud chunk, it will slowly seep out over time. Either way I thing your fine with one exception...

Have not seen the setup your showing. Looking at the latest 377 (6.2 EC) motor, I'm also unable to find it. Maybe a serial number would help Unsure why your using a remote tank but guessing it may be for fuel oil mix for winterizing. If this is the case, connect remote tank to input side of...

Normally the hub is not made to be removed from one and installed in another. Need another hub

spin on canister filter https://www.amazon.com/Moeller-033320-10-Micron-Separating-Filter/dp/B000MTB6XE/ref=sr_1_7?dchild=1&keywords=marine+fuel+water+separator&qid=1604159594&sr=8-7

Look down the throat of the carb and see if you see fuel dripping. If it is, remove the top of carb, clean needle seat and reinstall. Spraying cleaner will not clear the needle seat A spin on fuel filter would be best, and there not that expensive

Auto gas line is good enough for testing but should be marine USCG type A1. Also need to fix the leak Since your having to give it a lot of throttle to keep it running then probably need to get back into the carb, its probably flooding. Could be a spec of crud floated to the needle seat and...

Bit late now, but wonder if the height of the old and new impellers are the same

My (never finished) 105 Chrysler Conquor has a plate that says 105HP max. The Chy 105 was actually about 90HP, so upping to 105 would be quite a boost

Maybe they come Tuesday, Election day and all

When you do final alignment, the motor sits on the rear mounts with bolts in place just snug. The front of the motor is lifted just enough from the thermostat housing bracket so the bottom nuts can be run up against the bottom of the motor mounts, finger tight. The motor is lowered on to front...

Never seen pressure that low (15 psi) on a Merc. Depending on the serial number it would probably be 30 psi An issue to measure TBI is getting the fitting to connect inline

Most likely not all the lube came out. Have not seen lube look like that, nor stay that way letting it sit. Muc has mentioned before that to clean it out it can take 3 changes (just as I remember) Would be interesting to see if it ever does seperate

If the other gauges work (fuel, oil pressure, temp) then its either the gauge or wiring

Looks like Merc lube to me with a bit of water Maybe @muc has an answer
