"I have a 1985 Evinrude 90 horse. Motor would idle and start normal, but lost power above an idle. I noticed gas leaking around crank case. Trying to replace gaskets, but can not remove crankcase. All bolts are out and I have a space on top, but something is holding at the bottom."

"I recently purchased the boat. I have been told it was rebuilt a couple of years before he set it up. I really appreciate the advise you guys offer! I have decided to use liquid gasket maker. I injected that around the crankcase seal, rebuilt the carbs, and put the motor back together. After completing this, I tried to start the motor, but the shifter and key switch has no power. I have been reading and will try to check the kill circuit and see if I have a problem there."
 
"Unless You completely remove

"Unless You completely remove the power head and split the cyl and crank case the 'proper' way, You are not only wasting time but most likely ruining the engine."
