Twin engines

finally starting my fit out on my sr6, with twin 75 mariners.... now the question is do I put them parrell to each other, or set the engines slightly tow in or tow out???? on a previous sports cruiser I had they were set slightly tow out so both props were pushing power towards the centre of the boat supposedly giving a straighter drive.... cheers in advance

That's how I was told to set up mine by a bloke who knows these things. About an inch toed in, which equates to a TINY amount on the tie bar, be careful not to cut too much off. I made up a dummy in ply wood to get the dimension correct, measured the centres of the steering arm bolts & cut the tie bar to suit.
