Height on motor excel 1860 with 90 hp
Guys I ran a trophy 19 on a 1860 with a 4s 90hp 6” jackplate below the cav plate below drain plug and I got 43 gps @5400 VesselView rpm then as I kept trimming to gain speed it started to porpoise. Should I raise motor or lower it ??

Better Lucky Than Good!
Without knowing your current prop to pad measurements or seeing pictures the general rule is to raise the engine if you boat is porpoising when attempting to trim up.
