hp of the 6BT goes from 210 to 480 I believe. Depends on the model. I have the 250hp 6BTA, its a Fresh Water Aftercooler design. Good for low maintenance and keel cooled boats, older engine circa 1997.

The 6BT is rated 160-220 hp and is NOT aftercooled, The 6BTA JWAC "jacket water aftercooled" is rated 250-270 HP, The 6BTA sea water aftercooled is rated 300-370, The QSB 5.9 is available 220-380, and also 425-480. the 425-480 have significant differences to the 220-380. The QSB series are common rail electronic controlled engines.

Told him I didn't know, I'm just going to sell it.

I know nothing about diesels, I fiberglass. I remember a while ago my engine builder told me "we just turn it up". Don't know what he meant and really didn't care. They don't ask me how I fiberglass their boats and I don't ask them how they build my engines.

So today my ex engine builder stops by for a hello. I ask him what he means by "turn it up" and he answers, "put more fuel to it , its in the pump. You can turn them up until they run away". I still don't understand but I don't have to.

Not that easy to do it right. Pump, valves, cam, pistons, injectors, a/c I/c . You can just take a 210hp drill a hole and make it 370hp. If it was that simple why would anyone spend double for the same engine with higher HP?
