why are you mounting the oil filters in the back of the boat.seems like it would be a bigger pita to change..
I wanted the easiest way to change my filters,ex-nascar filter heads and #12 line.

Sutphen,

It’s all about decluttering the engine. It’s almost purely cosmetic. It, it actually makes it easier to change the filter without making a mess. And, if I does spill, it’s not being spilt on the engine; it will go into a relatively easy to clean up area.

I am also going with a Moroso racing filter, which would be fairly difficult to make room for on the engine.

Thanks. Brad.

where is your battery switch mounted?

Wildman,

Mounted on the back of the rear seat. The “storage” under the rear seat is actually intended as a built-in cooler, and there is actually two layers with what I can only guess is insulation between. I was able to pre-drill into that void and run screws into the first wall. Geographically, the switch hasn’t moved from its original location. I just moved it from one side panels that crates storage space on either side of the engine to this location on the back of the rear seat. I didn’t like the fact that I had to dismount the switch before I could remove the panel if/when I needed to get to anything on that side of the engine, like the fuel filter. I far more prefer this more “permanent” location.

Thanks. Brad.

Guys,

I found a spot to mount the ECM. I dismounted the breaker panel, then the enclosure box. Did some rewiring of the breaker panel so that the bilge pump is fed from the battery switch instead of directly from a battery (jumped off the “main helm feed). I then poked some holes in the side of the enclosure and made a mounting bracket out of Delrin with bolt patterns that matched those holes and the mounting holes of the ECM. The ECM connections are relative easy to get to, but it’s well under the gunwale, out of the way and safe from impact with objects going in or coming out of the area. Again, if water is getting to the ECM in this location, I’ve got bigger problems that a we ECM. I’ve already got the harness laced into the space above the transom and the relevant bits of it easily reach the engine.

I am currently working on rewriting the drive trim pump, feeding from a distribution block, which is fed via a 4ga wire straight off the battery switch.

I will also be running those two grounds that are run along the inner hull side to the grounding strap on the transom.

Thanks. Brad.

thats not a standard size oil filter I use,,its the big racing wix filter.you are a single engine boat,,then it kinda makes sense.I like running the engines outside the boat before they go in.

I left plenty of room for the filter. I don’t really think about it, but should I insulate the filter mount from the transom? I’m guessing it’ll be about as hot as the oil in the engine. Aluminum is quite thermally conductive. I’ve got some left over DragonPlate from a previous customer’s project that would probably work well.

I will be shortening the feed hose for the drive oil reservoir, but I will leave enough to allow for it to be pulled from the bracket, filled, then replaced. But I wanted as much elevation as I could get.

Thanks. Brad.

Guys,

I picked up one of , and I intend to wire it like this:

This still leaves the ECM out to dry in the event of a catastrophic ECM battery failure, but it's the best I can come up with, and no different than a single battery setup. On the right track?

Thanks. Brad.

Go to 8 minute mark on why it`s best to wire straight to battery.. why chance briking an ecu?

Dan,

While I agree with ZFrilly and Liberator…. I just can’t see how the ECM would care where it’s getting its 12v from…. I also agree with your sentiment…. There is just no sense in risking scrapping the ECM. Or losing the tune when we’re 30mi up the SouthFork. That’s why the rethink on the wiring.

I spoke with a tech rep from BlueSea this afternoon, and, verbally describing the schematic above, he indicated it will do what I want. Just thought I’d try and get some feedback from those who may have tried something similar.

Thanks. Brad.
