Finally ran the 184 last night in a tourny. My ? is I know I need a jack plate but what prop also? It is an 89 184DC with a 150 XR4. WOT it runs 58.9-59.5 @4950RPM and 22psi(water). It has a laser II 24 pitch prop. The reason I know it needs a jack plate is the higher you trim (past what it needs to be when running) the more water pressure I get.
