not sure .. the motor was puked when i got it.. a friend had a boat for sale .. i did not have the money at the time, so he sold it to another guy. the guy got exactly 8 hrs of on the water time and the motor went.
was told that there was old gas in the boat and the new owner wanted to get her out and see what she would do .. i guess the gas did not mix with the oil well, and or there was a detonation problem .. and bang....... fun over.
that is when i re-entered the scene and got the boat much less than what i was going to pay initially with a running (barely ... no trim tilt, etc) sea drive.
i was gonna scrap the sea drive and bracket it anyway.
not real sure how it ran with that prop ..
