Re: Mercury KH7 won’t fire

[Doug Wilson]

From what I have seen with the KE7 I have been working on would agree with Steve. Crank shaft seals are probably shot leaking if so that is what will
happen. Found the same thing on my WG7 Wizard if you put gas in the cylinder it would fire occasionally but would not start.
When you pull the lower bearing to get to the seal check and make sure it is real smooth otherwise good time to replace it.
Joe at Ferguson-Poole has them and the gaskets you will need, Old Mercs and others may too.

how is it motors multiply when the garage lights get
turned off?
