Drive question
 

Working on restoring a 1999 Sonic 358 twin 500 HP engines. Drives are both 1.50 R. Props are 28 pitch Bravo 1 with opposite pitch when installed. They have serial numbers 48-831916(on port drive) and 48-831915(on starboard drive). Was unable to get boat on plane on maiden voyage yesterday as I was experiencing severe cavitation. Front of boat came up high but wouldn't plane off. A buddy of mine checked the hubs and all good. I am going to switch props from one drive to the other tommorrow to see if this makes a difference. Just seeing if someone with drive experience had any input. Thx.

That seems like about the right size props. Might need 26's though.
Do you have them spinning in or out??? I'm sure you know that you will have to swap shifter positions on the cables or run them in reverse if you swap them side to side.
