Prop vs Crank HP

[mrbyll99]

I recently purchased a 1997 Bryant 192 with a Mercruiser throttle body EFI 5.7L that states 220 prop HP. I cannot find the crank HP rating anywhere...any ideas?

It runs very well (low 50's) but I am wondering if it is possible to re-chip and re-jet that engine for a little more performance?

Thanks

Depending on drive, add 25-30hp to get crank hp. But, it is better to compare at prop hp.

No re-chips and programming if possible is very expensive. There is little you can do to an injected boat engine, without a large expense.
