spark plug for chrysler 3.5 M# 3701

I would like to know about the spark plug for this motor. Chrysler 3.5 hp M# 3701 S# 6879. Also is this 2 cycle and what would be the gas/oil mixture?

Submitted by: chickendave

This is a 2 cycle engine that requires a 50:1 mixture. Unfortunately, we don’t have a parts breakdown for the engine. You will need to contact a Mercury Dealer. Try SeaWay Marine at 800-332-0803.
