this is a complete rebuild by the previous owner who is a marine mechanic. He had it on a 15ft. Cobra. it was too fast for that boat. I put it on my 15.5 Hourston. I backed off at 50 miles an hr. I put about 8 hr. on the ocean and about 9 hr. on the lake. I swiched to a 4 strok 75. I bought it last year when it was just brokin in. the cowel says 120 but it is a 140. can be seen running. sold with controls.
