Bell housing coolers.
 

So the new transmissions I'll be running need to be mounted using a race plate. I was planning on using the dual cooler bell housing I have, but I don't see how I can plumb them to work with the race mount. I don't have either of these in front of me, so is this a non issue, or am I going to have to run a different style cooler? Any suggestions?

a set of old style plates that go between the engine and bell housing.

The boat came with the old style bell housing that has one plate cooler on each side. The issue I see, is that the plumbing is going to hit the plate. So are you saying that, that style will work with this set up? The bell housing in the picture, I don't plan on using, there are no coolers in it.

I'm not familiar with that setup, but I can take some measurements off my dual housing if it'd help.

I may just have to wait until everything shows up and figure out what I'm keeping and what I'll reuse. Transmissions are all new to me, so I'm a 100% newbie in this area.

I found one of the bellhousing coolers was adequate for the trans in my case.

So are these coolers for the trans only? Or, one for transmission and one for engine?

Mine originally used both coolers for engine oil with an add on cooler for the transmission. Now I'm using 1 of the bellhousing coolers for oil and 1 for trans. I'm using the stock merc coolers with 8 ( I think) plates. There are coolers for the bellhousing that have more plates for increased cooling capacity also.

I haven't had much of a chance to dig into how mine are rigged yet, but I'm pretty sure it was like yours. One engine oil, one transmission. What drives are you running on your boat?

# 5 with Huber 1450 trans.

Ok, you are running a very similar set up. It also looks like you're running boxes as well. How are your transmissions mounted to the stringers. If you don't mind, next time you are in your boat, would you mind snapping a few pictures of them?

No boxes. The rear motor plate is mounted between the bellhousing and block. I can take a quick look and see what kind of room there is. Give me a cell # for sending pics if that's an option, posting here is a bit of a pita

the old style plate that goes between the engine block and bell housing should work, it has holes in it, that should work to plumb the dual cooler.
1. top mount starter pad on the bell housing needs to be machined 1/4 inch for tooth engagement.
(some come that way, i have 1 of each but w/o coolers)
2. engine/bell dowels need to longer ( trans to flex plate alignment

old swap shop ad. looks like the cooler plumbing would hit that mount. http://www.offshoreonly.com/forums/s...flexplate.html

Thanks!

That is the bell housing that is on my boat now.

And it looks like that mount won't clear the fittings...

As mentioned above, keep in mind that as you're mixing and matching these parts you might be changing starter and trans shaft engagement depth.

Got them, Thanks

I completely changed the wording of that last post after I got your text...
