Short of having a independant comparison on different makes of engine, any idea of what to avoid would help.
In place a Perkins D3.152 with a few problems. Looking to change, yes I could spend a fair bit to possibly sort the issues out with the Perkins but my feeling is change. Types of engine to look at Beta, Shanks (Barrus Shires, Isuzu & BMC all very dull I know, but hopfully practical. I would be looking at a new engine for a 57ft narrowboat any feelings / info on which way to go would be appreciated.
