Yup you trim the drive down so its level, put oil in the lower plug till it comes out the top. Quickly stick the bottom plug in after you install the top one. Use new gaskets at every change. I prefer the paper gaskets, I've seen a few of them yellow ones leak a bit. Also when draining and...
It just pulls apart. Then remove the setscrews and install the new one. When changing the motor, sometimes the motor shaft is a different diameter. You may have to contact the company and tell them the measurements to get the correct sizes on both ends.
Run it as is. I had an old outboard years ago that ran ok but the lower actually had a leak. Old Elgin if I remember correctly. Before the internet parts were hard to come by. I'd dump the oil after every outing and have a milkshake, re-fill and check/fill before launching. Used that thing for 5...
Do you have fenders in that area? Almost looks like it's been rubbed a bit. We have some at the marina that have those cloth covers over the fenders, the cloth collects dust/dirt and rubs the gelcoat like sandpaper.
Yeah, them long runs are a pain at time. If a dip in the hose it won't fill properly. Mine is a straight shot to the tank, and the vent has the loop to stop water intrusion.
There is numbers on your carb, that should lead you to the correct cfm. And kit also.
Also, be sure to replace the float, it usually doesn't come with the carb kit. If it's the brass float they are usually good. The plastic ones can cause issues.
I did something similar, but before gutting I measured from the floor to the outer edge in several places and marked/documented those measurements. glad I did. I adjusted all of it before stuffing the stringers in. She's good to go but in reality, I should have built the cradle.
Get the kit and install the electric choke. As far as the "quadrajunk" you actually have the correct carb for your motor. I can't tell you how many people want better performance, so they slab a bigger carb on there. Then they complain that they can't get it to idle right or other issues. I...
Not possible to leak fuel from that high up on any outboard. The only way it could, would be if the top seal was bad. Even then the crankcase is mostly under a vacuum, so it doesn't come out of that area.
Had two with similar issues at the shop in the last couple years. Both had everything replaced, caps rotors wires, fuel systems checked, before they got to me. Turned out the sparkplugs even though they looked almost perfect. Replaced them myself and did sea trials on both, Perfect! Sometimes...
I'd say that's just condensation from starting. When the air runs past the plates it's normal. When the motor warms up it don't do that much. I had a car that would freeze up when colder out and the throttle would stick due to the condensation, making ice. After warm up it was fine.
In early winter, we clean all the snow from the car before heading out. By this time of winter, we start the car, warm up a bit and say f**k it and go.
