I'm in the process of restoring a 1976 Irwin 42 Center Cockpit and planning to re-power with an Yanmar engine. My understanding is that the boat originally came with Perkins 4106 engines (approx 48 hp) and that they were a bit under powered. I understand many upgraded to the 4236 (75 hp). I want to install a Yanmar and would like to get some advice on best horse power. I've seen some 55 hp Yanmar for sale, but concerned that may not be quite enough power. Should I be focusing on 65 or 75 hp engines?
I plan to be a full time cruiser once the restoration is done.
Thanks in advance for everyone's input.
