Mercruiser 170 in the 2019 season - Now Bogging

[1966Mustang]

Today... Rewired resistor wire to regular copper, installed flamethrower 3ohm epoxy coil. Repainted and reinstalled rebuilt fuel pump using the AMK AFP-67. Cheapest fix on this boat yet...



Fiddled with cable and carb settings until everything seemed correct. Was watching the weather and decided on headed down to the ramp at about 5:20, launched, started right up, idled nicely. Went into reverse and forward fine, no hard clunks... mosey-ed down the creek into the Lafayette River with about 20Gal in her own tank... Had the 6 Gal Aux just in case...



Started ramping up the RPM's - now... this is where it fell on it's face a couple weeks back... (because it was leaning out due to not enough fuel pressure from the fuel pump) the RPMs came up... and stayed up... 25mph, 30, 35... didn't want to push it and get let down. Picked a speed where it sounded really happy and let it cruise. Not a bog nor a stumble.



Headed towards the shallow/marshy/residential/creek areas - creeping along < 10 mph- no stumbling, hesitations, etc. I felt like Mr. Allnutt going through the shallows observing the abundant wildlife. Wife popped a beer in celebration (full-disclosure I had a sip or two...)



Headed back to the dock around 7PM - figured I'd open it up and it hit about 40mph... came back to a nice smooth idle, to the dock, blipped reverse coming into the landing. Even got it on the trailer and home without mishap... All Good! Weather held - was quite nice actually.



I'm almost nervous - It all seems well... too well! For the first time since I've owned this boat! No smoke, no smells...



Resistor wire note: (my resistor wire measured ~1.8-2 ohm and is stainless/silver color, spliced into the electric choke. In my harness it goes - from the choke spade connector back along the harness, then makes a U-turn over to the front of the engine to the coil and pairs up with the wire from the solenoid. Purple - not purple stripe-ed)


Now that the engine seems squared away... I guess I can start making the list of things I know I need to do... rebuild trim pistons/lines, bellows, get all gauges working... etc.
