battery cable sizing will depend on how far the batteries are from the engine. I did not get the cranking amps for mine as the suppliers of the cable worked it all out after i had given them the cable length required.

for fuel pipe i purchased the mercury quicksilver pipe

if you want more info then feel free to drop a pm

RIBase
Battery / pipe

Jim,

Can't remember what size battery - but it's large!

As for fuel pipe use ISO7840 fuel pipe.

There is a special Battery which is designed for the Opti, I think its called the Optima. Expensive, but very good.

the batteries i used are twin 120 or 130 ah ones, they seem to work just fine, you can get them from where you are getting the engine, at around 70 quid each

the battery cable i fitted is huge compared to what came as standard! due to the length of course, but got that somewhere else but the engine supplier can probably do you as good a deal as anywhere

Sorry guys, I'm not asking the questions very well

I've got a cranking battery 180 amp hour 1000 cca & a deep cycle house battery for the toys, but I can't find any infomation on the load (amp draw) when starting the engine so that I can work out my cable sizes etc

I need the fuel hose id so that I can check the filter port size is ok, as I can get a good deal on Racor filter units, I'm looking at a 645 unit with a maximum flow of 170 litres per hour

Not actually designed for the Opti, but an excellent battery and supplied with the Verado.

The requirements for a 200hp Opti battery are:
1000 marine cranking amps, (mca) or 800 cold cranking amps (cca)
