Where are the block drain plugs on a 4.3 chevy marine engine?

I have a 2004 60 hp yamaha 2 stroke outboard engine that doesn’t start or run well. Once warm and in the water it will idle in nuetral and also in gear. It accelerates in neutral but will die or lack power if I increase throttle while in gear. Engine will somtimes get to top speed but often while running at top speed engine will start to slow rapidly. Engine has full range of operationout when out of the water where there is no load on engine but is still difficult to cold start. Before these recent problems the engine sat up for several months and I had to change the impeller and spark plugs. Spark plugs fire, cylinders have proper pressure of 100, 100, and 110. I cleaned some fuel lines and filters and got new gas.

We have a pop-up with the sink that folds down. We need to replace the sink drain from the sink to outside, but the only flex drain hoses that I can find have a hose only 26 inches long. I know that will not be long enough to go from the sink to the outside of the camper.

Do you know if any place I can go to get a sink drain system with a longer hose. The contraption (I don’t know what it is called) at the base of the sink drain has rusted off so that the swivel part of the drain system is gone. We currently have a garden hose connected to the pipe coming directly from the drain, but when we close the camper, it pops off.

Do you have any suggestions?

Thanks

LX 188. Engine suddenly dies. The fluel in the bowel of the fuel filter is empty. If I crank the engine the filter becomes dry and is collapsing some but the engine does not start. When I remove the supply line from the fuel pump to the carberator and crank the enginge there is a strong stream of gas being pumped out. I tap on the carberator ??? is the float is hung not allowing fuel to enter. Cranking the engine with the line off refills the bowel of the gas filter. Reattache line to the carberator===engine starts. Ran perfect for 20minutes then suddenly died. Repeated all the above and engine again started. What to do to fix this? Thanks

Does the John Deere series 100 lawn tractor have some sort of safety feature that shuts the engine off if it gets dangerously low on oil? I was cutting grass this morning and the engine sputtered and quit. I got off the tractor and noticed that the oil drain line plug was open and dripping oil. Have I ruined my engine or can I refill it with oil and continue on?

I just purchased this Yamaha boat w/Twin MR-1 140hp motors, less than 100hrs (60 prox)and the starboard motor only reached 8000rpm on a 10000 redline spec (the port motor reaches 10000rpm. I have replaced the spark plugs immediatly and now the motor reaches 9500rpm. When the plugs were replaced the plug wire top of the plugs had a black powder residue (like graphite)and #1 & 4 plug electrode end were black minimal soot and #2 & #3 had a white color residue on the ceramic.

Any suggestions to attain the full 10000rpm?

A Yamaha dealer is 100 miles, so I would like to fix myself if possible. Thanks
