Re: yachtwin help
Yep, the little 4hp models were great motors! They were essentially an evolution of the earlier 3hp models, which were legendary for their smooth idle, easy starting and long term reliability.
One thing I will say, though, is to run it a little fat on the oil, as it still has bronze babbit bearings at most of the main journals. I've got a box full of junk blocks that were likely a result of running at 50:1. If it were mine, I'd run it at 40:1 or even 32:1 if it's getting hard use...
