Re-wire / Re-power help

[DUKE]

Hi All
My 1989 V20 took on water last year and needs repairs.
After sitting in the yard for over a year I am now considering re-powering and re-wiring it.
That said, I could use some recommendations in the Monmouth County NJ area for a respectable used outboard for sale, 25" shaft 150-175hp. And a reliable mechanic or handyman to do the re-wire.
If this doesn't work out I may sell it as is or part it out.
Thanks,Duke
