I have twin 6-354 Perkins
diesels with Walter V-Drives in my new-to-me, but older, 40 foot steel trawler
which has never
seen salt water
That is going to change in 2014.
My questions are: Can someone help me with designing Keel
(of the 1" to 1&1/5" Pipe size for both - engines and v-drives. I don't have any info on volumes of cooling
fluid needed for either unit to provide adequate cooling
. I don't want to run salt water
through this machinery.
What are your thoughts on 3 blade
verse 4 blade propellers? My boat
has 3 blade props
on it now ( 24 x 20's) ,
and it came with 4 blade
(24 x20) spares. Can someone tell me which
would be more economical to operate?
What are your thoughts on the pros and cons of each?
