Ignition box mounting
 

Anyone ever notice that ignition boxes are almost always mounted on the engine and the instructions that come with the boxes say to never mount it on an engine. Any thoughts on this? Any good mounting alternatives?

Vibration would be my thought.

I mounted mine on the bulkhead in the engine bay right in front of the motor. That way the wires to the battery and the engine harness remained short and I could try and hide the remainder of the coil and dist wires along the block. I used the rubber shock mounts that came with the box and just wired everything to fit the length from the engine to the bulkhead. Easy to get at and easy to replace if it fails. (Which it was when it did!)

I know vibration is the issue. I find it curious that they say not to mount them on the engine but that is almost always where they are mounted. I have two new Crane boxes to mount and I am wondering if it might be better to mount them somewhere other than the engine. Ghostrider, that looks nice and clean. My bulkhead is loaded up with pumps and lights and inverter etc.

The mounts they sell come with little rubber bushings.
At least mine did. if not u can make some. the closer they are the easier and better it is.

We mounted one to a transom one time using a bicycle inner tube cut and folded multiple times for add cushion. It seemed to work well.

I used the innertube idea on an electric fuel pump in a car. That was to keep the vibrations from the pump away from me though. Holley Blue. If I did mount it on the engine I was thinking of drilling out the holes in the mounting plate and using rubber grommets in the bolt holes where it bolts onto the engine.

the heat of the engine room is why they want them out of there, try under the rear seat if you feel you have to have one...Rob

Yes, I do need one. It handles the timing curve.

BCK I have crane boxes installed in my boat with Crane coils. I can Email you a picture of what I did. i mounted them on a plat with the coils and Mercathode/breaker and then mounted the plate on the back transom. Worked out great. the transom should be the best place for lack of vibration and the most stable surface in the boat.

What Crane ignition box did you go with HI-6??

Yes, I'd like to see the pics. My boat was built with an aftermarket box(Nu Tech Firepower), designed to work with the TB Dist. When 1 of them went after 20 years I opted to keep the TB Dist and get the 6M marine box from Crane. It was a straight swap didn't have to change a thing.

The 6 M is MSD ??!! mhhhhhh ,or not ??

I think the Crane numbers are HI-6M M for Marine. I almost positve that's the number on the face of the unit. These units have 6 built in ignition curves with a rev limiter.

Where do you live I see it says Western NY. I'm in Rochester

OH,,,,ok. makes sense !!

Mine have been on this bracket since 2003.I like having everything mounted to the motor, all self contained,you can pull the motor off the dyno and go straight to the boat,exhaust,water pump,fuel pump,oil and water system all on the motor just like it comes out of the boat,keeping it simple.I first made it in alum,cracked it in the tight bend, instead of putting a gusset to keep it from moving, I just made it out of .060 stainless, stays polished out better anyway:ernaehrung004:

hope this helps

Yes, Crane Fireball Hi 6M with built in timing curves and LX 92 coil with Thunderbolt Dist. Rob, your setup is exactly what I had and what I was going to reuse until I started wondering about relocating it off the engine. Thought it might help it to last longer especially since I guess Cranes future might be uncertain. Also I noticed while reading the online instructions that they may have added a couple more features to the newest box. Looks like an additional curve and some sort of anti theft feature maybe. From the website it looks like Crane and most of its people were bought by S & S (the motorcycle engine people?) and are still operating. Cocktails, I live near Buffalo. Boat hasn't been in water in years- a project I lost interest in and funds for. Finally finishing engines. I will be able to say I have the most expensive 23 year old Formula around, although I probably won't brag about it.

Brian Where do you live near Buffalo, I do all of my boating in Buffalo. I'll be there this weekend on the river, Shanghai Red's , The launch club, and down to Canal days then probably to Sunset on Sunday. get that boat finished and well see you on the river. Where do you go boating.???

I live about 35 miles south of Buffalo. When I was using the boat I went to all the same places and up on the river alot. I kept the boat at the small boat harbor because it was closer and had wider floating docks. Friends keep theirs at the Erie Basin because they like to party downtown.

I'll be at Erie Basin this weekend. Tell all your Partying friends to stop by D dock. We like a good party. A bunch of my friends have boats on D-Dock.
Good Luck with the Project. Send me your email I'll email you some pictures of what I did to mount the boxes.

I have a brand new never used stainless engine mount ignition box mount from Teague Marine. Mounts on the end of BB Chevy heads.It's heavy thick stainless plate with anodized standoffs and 3/8" allen head mounting bolts.Also has stainless bolts and nuts and has drilled and countersunk holes to mount a MSD 6M box on one side and a Soft Touch Rev Limiter on the other side.http://teaguecustommarine.com//store...199_179_83_536

Teague gets $83.50,I'll take $30 and shipping. Anyone interested PM me.

I mounted my MSD #7 marine box's on a bracket, that I made, on the inner transom plate. I have run this set-up for years, with absolutely no trouble.
