Engin operating angle

[KKat]

Hi,

I am nearing completion of building a 55 foot plywood/epoxy Catamaran in a small fishing village in Malaysia.

Although the locals are well versed in the building of wooden Sampan fishing boats when things get technical it's hard to get advise.
I am fitting 2 reconditioned Nissan marine SD 33 Disel engines as used in the Bayliner 3270 and the Nissan Patrol and C 80 SUV's.
To accommodate the propeller I will have to install the engines at an angle.
My questions are :
1, What is the maximum angle can I safely operate the engines
2, What is the maximum angle to the water line of the shaft/propeller allowed.

Thanks for any advise you can give me.
Brendon.

Look up engine manual - ours says the angles.

I think engines are different - a car one may be built to run level but if it comes from a AWD then it should be fine.

FWIW I am doing a 50 ft cat
Engines mounted under beds aft of cockpit BH in typical cat fashion
I thought the 8 degree offset gearbox was to much angle
with longer shafts and 3 bearings I managed to get them in with a 4 degree shaft angle
