Re: have you heard of a mcculloch 3 cyl?
Back in the mid '60 time frame, McCullogh took their 40 hp twin, added a 3rd cylinder and came out with their 60 hp. Later they upgraded it to 75 hp. Both were sleek and seemed to be well thought out. Have no idea as to how they performed. For some reason they weren't all that popular. Have no idea as to why. I had a 22 hp twin of theirs at that time of a 13' boat. I took it 10 miles offshore to Ship and Cat island south of Biloxi/Gulfport, MS, numerous times. Never let me down. It was no speed demon on that rig, loaded to fish out there , but it was all I could afford at the time.
There are www sites with pics and other things around.
