Repower SeaRay 310DA 2x 7.4MPI bravo 3 to 2x mercruiser D4.2L D-tronic bravo 3
Here it is. I have a very good deal for 2x mercruiser D4.2L D-tronic 250HP bravo 3 2003 with 150 hour they comme complete with electronique drive bravo 3 X diesel, prop,........ (so far I dont know the ratio of the drive is it expensive to change it?)
from another repower boat. The guy need to sell them fast
Im wondering before to go further if I could do someting like this and wath should I be aware of any info or tip is very welcom
So Far I found those info
-I now have a Bravo 3 2.0 ratio with 24 pitch and cruise at 3200 RPM wondering wath drive ration should I use
Find my boat was available with the same engine mercruiser D4.3L but 225 HP so 25 HP less
I call searay dealer they give me the ratio pitch for my boat, 1998 they where using 2.0:1 and 26 pitch for the D4.3L D-tronic 225 HP. Wondering if it will be the same for the D4.3L D-tronic 250 HP. RPM difference between both engine are 200
Also found on sea ray 310 manual from 1999 to 2002 they use ration for 1.81:1 and 22 pitch for the D4.3L D-tronic 225 HP
PS sorry im french native so my english is a bit limited
