Hi I purchased a 1980 Gulfstar
44 CC. It has a Perkins 4.154
M with a Borg Warner 71 CR trans according to the documents The prop was not original and some investigation finds me questioning if it is the right one. It is also severely corroded by electrolysis
. its 19 X? 3 blade bronze
. I found a thread with specs for the MK11 that show it has a hurth
trans with 2.57:1 reduction the prop size was 20 x 17. The Perkins
has a WOT of 3000. Any idea what the original prop size is?
