Seeing as I am new to this site, I might as well insert my little story. My father had a basket-case old 5hp murcury(about a 1950)in our basement. Well, I was a budding mechanic(this was like in 1977 and I put it back togeather and brought it up to the lake that they were vacationing at. I mounted it to the bracket on the 17' canoe(we normally had a 1938? 3hp on the canoe) and tried to start the motor. I finally got it to start, but it started up at full throttle and I've never seen a canoe take off so fast! I think about 10' of the canoe left the water. The engine died after about 5 or7 seconds of WOT and when I looked back at shore I was maybe 300 yards away. Those old Mercs where underated on HP,so Iv'e heard. Boy, the good ol days. PDS
