Hi Folks
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 Coolers
(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?
