Title: BW 71C oil circuit/cooler
Post by: Ed. on May 02, 2023, 11:39:48 AM
Hello,
I'm about to change Paragon SAOD for BW Velvet drive 71C. I've read a lot on this forum but still strugling with some details:
1) what size of oil cooler for BW is sufficient? I'm considering to go for Bowman DC50. (https://www.asap-supplies.com/products/bowman-dc50-oil-cooler-40hp-3-8-bsp-oil-22mm-id-water-203010) What type of cooler are you using guys? Can you post some pictures of your instalation please?
2) I'm not sure what's oil inlet/outlet on my BW as I bought it as you see it on pics.
I'm just guessing it regarding this post (https://pearson365.com/forum/index.php?PHPSESSID=ac04aabf6bd77860013b999706199146&topic=1124.msg6747#msg6747) as manual shows inlet/outlet in a place I have no holes.. probably old models? .. What's confusing is the holes are different size (bottom one is bigger) and they're "sealed"..
3) Is the inlet/outlet defined by how is pump indexed? (mine should be LH) Any advice how to figure it out?

Thanks for any inputs/advices!
E.

P.S.
For anybody else searching where to plug oil cooler this thread is your answer. (https://pearson365.com/forum/index.php?PHPSESSID=9e50812819b61a1325b7d90d9019e259&topic=350.msg1386#msg1386)

That looks like the right cooler. I need to get to the boat to check the hose placement, but I do know one comes out of the top of the case. I believe that is where the oil flows out and the other is the return. The water should flow in the opposite direction through the cooler.

The couple I have seen have been mounted under the Ice Box.
 So raw water flow would be V-drive, trans cooler, Eng.
