Bouht Chrysler force 125 it been sitting 5 yrs. Hooked it up to my boat stated right up sounds good. Let it run for 5 min. It. Ran hot. Waiting for Monday to get waterpump kit. Since I just got it I thought I start it justt for a moment. It started right up. Then I noticed oil on the prop cone it was coming from. The exhaust does anyone no the cause for trhis. Thanks guys
