yea i know was just wonder more about the setup... seem simple and cheap.

has anyone tried this style?

The only diffrents on the marine aproved ones is the hole in the bottom has a screen over it !!!! like a flame arestor ..only for sparks...TO FUNNY

other then that they are 100% the same !

Look at these http://www.performancedistributors.com/marinedui.htm

For those who ask about protecting the inside of the MSD from rust an annual spray with CRC SP-400 long term corossion inhibitor will do great. I do not boat in salt water but I used this for several(7) years and it worked well. I did this in the Fall during winterization. Just remove the MSD cap and spray with a light coating of the spray. Wipe any dripping excess off. The only thing that seemed to still rust were the springs. You'll have to get this from Grainger or like company. It is mostly used in food industry machinery. Protect the box from voltage spikes with a capacitor and you will be good with the MSD. It just goes inline on the power wire to the box.

thats what I run...just get the vac advance eliminater kit, and they work awsome....also the HEI wire ends that plug right in, makes the install a snap...

im no motor guy but dont want the timing to advance in a boat as u give it more rpm?

u cant just block the vac line?

or do they have mechanical advance?

I am by NO means an engine expert. But been seeing alot of crank trigger ignitions on cars the last couple of years. I think Eddie Young did something awhile ago too. To my knowlede these systems don't use a distributer at all. I'll see if I can find the thread from Young Performance.

Here it is.
