Bump? Thinking about the Hardin unit right now...

I ended up going with them, very happy! Kept the oil temperature nice and stable!

Good deal! All the leak issues were resolved?

Also, do I need to drain the oil to install these, or will it all be in the pan? Suppose the boat had been sitting unused for a week prior to install.

Yes, all leak issues resolved.

For the most part most of the oil should be in the pan but you will get what ever is in the filter and the oil passages leading two and from the filter.

I ordered one. Hopefully this will keep my oil temp from swinging so wildly. >100* at idle and 180ish running.

I used a canton and the temps stays @ 210

I just thought I would just let anyone who is interested in this item know, the banjo problem still exists. I was in a hurry to get my engine going and didn't notice the end mill marks on the banjo fitting. after pulling the bolt two times and re kneeling the washers with no luck, I finally pulled the line off the banjo fitting so I could get it out to see what I had missed. I ended up spending a 1/2 hour with a flat file too fix the problem. no leaks now. Wish I would have found this post earlier.

Nice to know they've been aware the problem and it's exact nature for 2-3 years now and have made no attempt to fix it. They could at least look at it before they send it to check it (if the problem isn't with every one). Nice company. A $300 part that is likely inaccessible after installation. F##k the customer.

Installed two last year had one side leak and one has been fine since install.
I installed new gasket and O ring and has been fine since.
Ended up using the block adaptor, remote filter mount, 3 x 16 oil coolers and -12 lines for oil system, works great.
