Hi,
Fairly new to outboards, brand new to mercs, have a few questions about this motor i acquired more or less from being thrown out

1) I can't seem to make it trim all the way down?? i'm baffled even with the pin right out??
2) engine starts but there is a tonn of debris/carbon/burned residue in the motor casing, what are the first things I should check??
3) can i figure out the exact year from this serial # ?
Thanks

How many hp is this motor? Or what Model is it, should say on the hood or possibly by the exhaust port.
