We was discusing engine load versus rich/lean. Interested in info and solutions...under load rich, less load but still wot = lean.
Ive torched a piston from nothing more than a gear change. And it happened in a heart beat.We was discusing engine load versus rich/lean. Interested in info and solutions...under load rich, less load but still wot = lean.
anything you do that loads the engine harder will have an effect on the cylinder temps. The A/F remains the same, but the cylinder temps can shoot up. Thats one reason the dyno jetting tends to be a little rich over what performs the best in real use. The engine is simply loaded harder on the dyno than you can repoduce in the boat unless you gear it to hold a given RPM lower than your peak HP.Say you where running the same gear...what would you do? I know I could log book prop to.......(for you gears)
Oh, well thats a horse of different color. I agree 100%, except the part about WOT all the time and the Gs in the corners. Are we talking about the same Paul?Let me help explain here...what Paul was telling me was that under load in the corners, it's pig rich, but get on plane and up in rpm going down the straights, it leans out to where it should be. I think it might be sloshing fuel through the ven tubes in the corners, becuase dynamically, there's no reason for it to richen up in the corners at lower rpm. Oh, and same throttle position...WOT all the time.
