Yippee, it runs...
Today was full of ups and downs. Spent most of the day chasing the fuel system, reading the Seadoo manuals and the Mikuni manual for how the fuel was supposed to flow through the fuel pump and into the next carb. This is what I had setup from when I pulled the motor out of the 'Doo. The fuel is fed from the right at the 'Y' and the 'return line' comes out the other side of the left carb going to back to the return on the tank. Remarkably I never got any fuel out the return side.
Took the carbs apart several times and they were decent inside, finally rigged a little gravity feed fuel tank like this. Worked great because as the motor ran off of the fuel I poured down the throats I got bubbles out of the tank line...
Yep, hooked the fuel lines up backwards and sideways...
Wiring redo for the variable trim system, third switch from the left. Used two double contact (NC, NO) blocks and wired the motor leads out one side of the contacts and 12vdc to the normally open contacts and ground to the normally closed contacts so when you flip the switch one way or the other it changes to polarity of the motor leads as it puts power to the motor. Simple and effective. Now I just need some more four conductor wire to run back to the unit.
Up inside the console, wires wires everywhere.
The mess... I hope to revisit this later and straighten everything out. It looked good before I realised the cables were mislabelled.
Just some green light porn. I put little green LED's in the switches and powered up the rear deck lamps. There's also a lamp shining up at the gauges since they aren't backlit.
Other issues that came up were it wasn't charging, found the 15A fuse blown, probably from the miswire. I'll leave the battery hooked up overnight to make sure it isn't draining it. The best part is now I just breath on the starter button and it comes to life. Sounds good but I can't run it long without coolant and it was raining all day so I didn't pull it out of the garage or get it wet. Oh yeah, the tach works great with the resistors hooked up.
Now I have a seven on to do, twelve hours days too, before I can get the boat in the water. I grabbed the new trailer lites and fenders so I may get them on during the evening to get ready to splash this puppy.
