I recently blew the motor i had on it which was a old mariner 175hp. With that motor, same prop, i was running 63 mph at 5600 rpms. The 200, same jackplate height, i ran 62mph at 5200. Raised the jackplate 1" and lost speed but gained rpms (57 @5600). Water pressure is at 12 psi right now. Prop is a 24 tempest. My elevation here is 3,000 ft above sea level. Holeshot isnt great. I carry about 30 lbs of tackle in the bow that i know isnt helping it lift which my boat has never lifted. I did have a 23 quicksilver prop that had no vent holes and it ran 61 @5400. I had it sent into have cup added and it fell on its face with 56 @ 5300. I tried a 23 tempest before i raised it and i had a better holeshot but lost 4 mph.
Kinda stuck on where to go. If i drop to a 23, ill gain more rpms and i will most likely have to drop the jackplate to make up for higher rpms.
