Remember if you haven't already got Stainless steel leads you will need to change them, old carbon leads won't stand the increased voltage and will break down under load.

I have a her on my chevy and Pontiac at home , they are trouble free

 

[fred247]

"Ok" your choice.

 

[Dodgy Diver]

"Ok" your choice.

new electronic over 30 year old points and condenser , no contest

 

[fred247]

my comments were about the leads not the Hei dizzy - good choice !
the engine bay gets a lot hotter than the ambient temp under the bonnet

Bear in mind that distributors for marine petrol engines have "flame arrest" features. In the event of petrol vapours ( e.g. from a leak), in the engine compartment entering the distributor and being ignited; to prevent the flame from getting out of the distributor with potentially disastrous consequences.. Basically a fine metallic mesh on all the vent holes in the distributor body, same principle as was used in the Davy miners lamp to prevent methane explosions.

Meant as a helpful hint; MY 2004 VP 5.7 GXI ( GM engine) had a flimly plasic bodied distributor. I repaired some damage to the bits used for clamping the cap on with brass bits. Those mesh screens were there, but to be honest were not as complete as they should have been.

so back to batteries and my cunning plan
I have purchased 2 110 ah leisure batteries and a 644 battery
now the boat already has the isolator that says . off , 1 ,2,all so the plan , use the 644 as a starting battery and connect it to number one . then connect the other 2 batteries to number 2 but also directly connect them to the aux power for all the boat , then use a voltage sensing relay that will charge both batteries once the engine is running , this way I cal leave the isolator on number one , this will mean the 644 will be there just for starting . the other 2 will not be connected to the engine circuit . how ever if there is a issue with the engine battery I can turn the isolator to all and then this will help if the main one goes partly flat for some reason . the cabin has a isolator as you walk in anyway . well thats the plan and I have ordered a 40000w sine wave inverter which will run a kettle for a cuppa .
