RE: Get home outboard for 32' Trawler
6 -7K get home?
That will take huge HP.
With a 32 ft boat it is perhaps 26. 28 ft LWL.
A speed of 4 to 5 K would be much more realistic .
A good OB bracket and the engine from a condom boat of about 20 hp should do.
16,000 divided by 2240 is only 6 or 7 , 2x that is only 13 or 14 , so a 20hp OB should be fine.
To contemplate this you should find which OB in that size range has the largest reduction gear ratio , and can swing the largest propeller.
Would be no big deal to loose some top speed from the dink, and mount a spare PUSHER prop when using the OB as a get home.
You could also operate with the dink alongside ,tug boat style , in smooth water only.
