Wot 4900 rpm

[Down2Race]

I have the Indmar 5.7 TBI 350. Re-propped with the Acme 543 and it pulls hard! great out of the hole and top speed still 43-44mph. Im just worried about the WOT RPMs. Specs say 4200-4800 for this motor. 4900RPM is WOT unweighted other than me and a 350lb sac in the front locker. I add another 1600-2000lb when surfing/wakeboarding. Is there a rev-limiter on this motor?

Previously tried the Acme 541...Great improvement over the stock OJ 13x13. Didnt pull near as hard as the 543(not as much torque/acceleration), but same top speed at 4700 RPM. Generally, the motor runs 200 RPMs higher throughout all speeds with the 543.

I wouldn't be concerned about 100 RPM read on a 15 year old stock gage. They are not that accurate!
