I wouldn't rule it out at this point I'm going to change the water separator filter today and when I go back to the lake this weekend to try and tune it on the water I'm also going to bring a fuel jug from an outboard motor that I'm going to plumb directly to the fuel pump to rule out that...
Yup.. Just going to focus on Carb if fuel delivery from tank is ruled out.. Only thing it cab be at this point
Timing is set
Valves set
Motor is fresh
Cap/rotor wires look fine and pretty new
Just being how smooth and clean it runs on muffs it seems like it's got to be minor adjustments... I...
I do not have an exhaust shutter valve on my exhaust pipe and when the issue occurred when I had it in the water the transom straps were off and I was even out in the middle of the lake when it died the only reason I'm thinking exhaust back pressure is because it runs fine on the muffs with no...
I'm pretty sure I would know if it's running on two cylinders on the muffs
, it was converted to electronic ignition by the previous owner it has a pertronics igniter on it
Interesting... I don't know since it runs great on muffs then dies on the lake I'd assume to opposite it would need more fuel with the water back pressure I couldn't see it wanting leaned up but when I go back to lake I'll see if That makes a difference.
I guess I can crank a turn in the throttle screw to see if I can get it to light. I couldn't get it to remotely stay alive in the water the other day. It would catch and bog then die... Both mixture screws set about 1.75-2 turns out timing at 6-8* per sticker on valve cover.
its been raining so I took the time to pull motor back out to source a leak i had, going to test my leak repair and then put motor back in and head to lake for some on the water tuning.
The carb has a sierra marine tag on it and the previous owner stated it was new from them, but I obviously...
Not sure on pressure, I'll have to get a gauge on it.. It has a vent because I overfilled tank and it spilled out. Then I'm not sure what an anti siphon valve is... Also how the difference between hose water and lake affects it
Mercruiser 3.0 that I bought as a project. I rebuilt the engine and have it running great in the driveway on the hose with the muffs on however when I get to the lake and put it in the water it stumbles and dies and will not start back up.
Timing is set at the sticker on the valve cover which...
well i see on michigan motorz that they sell the 12-3/4 flywheel for this purpose like the link above shows and then the coupler id have to decide which one... just didnt want to spend 450 on a flywheel and probably 200 on coupler.. not sure if there were other options to save the money. its a...
that would be great but this boat aint worth that at at all.. so pretty much im stuck buying a flywheel and coupler to fit this engine into my older bellhousing so it will bolt in place and the coupler will work with my current mc1 driveshaft
so id be able to use my bellhousing and I just have to buy the coupler? I was under the impression that you needed to run a smaller flywheel to fit into the older boat bellhousing?
