I need help identifying motor. All plates are missing. The following are the only numbers I can find without taking things apart. the cowling says "Yamaha 70 Precision Blend"
On the plate between the trim hydraulics:
"6H1-15" is forged in
"7B-1088" is below it stamped in the metal
There is a recessed circle about the size of a dime in the block on the starboard side behind the carbs. that says "90207"
all over the engine there is forged in "6H30 4" "6H30 5" "6H30 0" followed by a "Y-1"
There are no other plates/numbers. I havent taken anything off to find the freeze plugs, I read another post where the serial # will be stamped in the plugs.
Any help is appreciated, I am ready to start working on it.
