I purchased a 1980 gulfstar
44 CC. I took off the prop for inspection
and found very bad electrolysis
had deteriorated the prop. after taking it to the prop shop I found out that the 19x17 prop was the wrong prop, someone must have found a used prop that fit??
My question is what is the original prop size? Motor
is a perkins 4.154
M with a borg warner 71 CR.
I found the specs for a gulfstar
mk11 showing a prop size of 20 x 17 with a hurth
2.57:1 WOT is 3000 Rpm
. Any help with my search would be appreciated.
