5.8l ford...... is there anything that limits rpm on this aside from the operator? Dont k ow if there is supposed to be a throttle stop or something similar. Aside from an msd box with a limiter chip.... im not sure.

I cannot answer to your engine specifically.

But I think that most marine engines do have a Rev Limiter to prevent engine damage if you have the prop come out of the water, or strip the prop hub, etc. It is likely to be set quite a bit higher than your maximum recommended rpm. For instance, if you engine shows a maximum recommended WOT of 4600-4800 rpm, then the Rev Limiter might be up towards 5500rpm?

Old tech carbureted engines with points/condenser ignition had a Rev Limiter on the Rotor (in distributor). I'm sure I hit my Rev-Limit a few times with my previous 4.3L going wild jumping waves in the Atlantic.

Newer Fuel Injected / Computer Controlled engines can have a Rev Limiter using the Ignition or Fuel Injection. Maybe someone will have a better answer for a 5.8L Ford, but my main point here is that you are probably NOT hitting your Rev Limit if you have correct prop in the water.
