Tohatsu M30A3 vs M30A4 rpm and props

[nfs1]

I have a M30A3 from the 90's. I've read a few different manuals for 30hp 2 stroke Tohastu's and was wondering what the correct rpm range is at wot for the M30A3? The M30A3 manual says 4800-5500 rpm (seems low) and the M30A4 manual says 5,150-5,850. It's confusing because on paper the M30A3 and M30A4 are nearly identical engines.

I'm experimenting with props so this would be really helpful to clarify.

Thanks

I would stick with factory recommendations.

Yeah, I'm propped for factory recs. Side question, do you know where to find cables for steering, shifting, throttle for an M30A3 and also a NS40C? Only ever used tillers so trying to figure this out for a console. Thanks.

Any steering setup is OK. I prefer single push-pull cable to twin tiller cable for safety. Throttle and shift are standard, off the shelf clamp type 3300 cables.
