Bula from Fiji
I have been running a Cummins 6 BTA on my 40' Semi-dispacement hulled, aluminium game fisher
and need to replace it.
Here are the engine
details: Make: Cummins / Model: 6BTA 5 – 9 – M1 / Year: 1994 / CD 339 5-9 / Series: 403 / Serial
Number: 45095665 / Shaft Horse Power: 250 hp.
I have the opportunity to get a replacement long block from the U.S. with virtually free shipping
out here to Fiji
I have been told that the 6BTA engines come in a variety of Horse Power ratings - 170hp to 370 hp.
I am hoping to get a higher powered engine
and, of course!, to reduce costs as much as possible! I will also be replacing the fuel
injection pump and turbo.
I am wondering if the blocks are indeed the same and parts
from my existing 250hp engine can be interchanged with a replacement (say) 370hp engine? Same engine mounts? Same manifold? Same gear
box mounting? Same starter? ... an anything else my limited knowledge has not thought of.
These are the details of my present gear
box: Gear Box: HURTH Marine
/ Gear Box Ratio: 2.85 / Model: HSW 800 A2 - (ZF 80 A) / Serial
Number: 20 14037 C.
I would like to stay with the Cummins as my old one has been reliable and the knowledge I have built up on them - although not a lot - helps me keep my old girl going!
I would welcome any input and or information.
