Hello all,
Thanks in advance for any help or advice I may receive for my problem.
Motor: 75ELR77S
I have a Seloc manual that covers this motor.
Compression is as follows:
130
125
120
Items I have replaced:
Water pump
Fuel pump
fuel lines (from tank to carbs)
rebuilt carb's...completely including carb kits.
Installed Tell-Tale on block.
New oil in lower unit.
Spark Plugs
Starter soleniod
I just purchased this motor to fix and put on my bass boat. I had this motor running before the carb rebuild, but in the water it would die if put in gear. Forward could sometimes be eased up in RPM's before it would die out, but reverse would die immediatly.
After rebuilding carbs, exact same problem, it would die in gear. Both before and after, it would idle great and RPMs could be increased with the warm up lever. So, I decided to do a decarb just for &^%'s and giggles. Ran a product my boat shop recommended (made by teleflex?) through the carbs, let it sit, and during the run period after letting it soak, after about 5 minutes the RPM's jumped slightly and had a very smooth idle for about 4 seconds then died. Now it has no spark.
I have eliminated the key switch by disconnecting the appropriate wire from the power pack. I disconnected the rectifier, but still no spark. My manual says I need a neon tester to check the stator and power pack, but I can't seem to find one. I tried taking a few measurements with my multi-meter, but the manual is a little hard to follow. If I did it correctly, my stator resistance is about 6 ohms throughout. I can't seem to get the 150 volt reading that I found on the internet. In fact, I can't find any high voltage readings while cranking.
My question is this, should I replace the power pack, stator, or timer base first? Money is tight this day and age, and my wife is about to make me live in "that stupid boat"...
Thanks again for any input.
