Hello, i am looking at a Mainship 30 Pilot with a Cummins 240. It topped out around 15 knots at around 2700 rpm’s. Wondering if these readings sound accurate for this boat? Thanks in advance.
Welcome aboard. What Cummins is in it? My 450s top out at 2600RPMs.
I think you may have the Yanmar 4LH 240, a 4 cylinder engine, in that boat. 15 kts sounds about right. But 2700 rpm is way too low if it is that engine. Should be 3,300 at wot.
Could it be that you really do have a 6 cylinder Cummins? The 6BT? 2700 rpm at wot would make sense for that engine. Never heard it referred to as 240. Usually 210 or 220 hp.
