Should my new 5.7 have an engine oil cooler?

I just bought a new Indmar 5.7 engine, which I'm going to put in my '77 Luhrs 28' (see thread in Resto section for photos). Anyway I notice the engine didn't come with an oil cooler. Do some Mercruiser 5.7's run without it?

I'm thinking cooler oil is always a good idea, so I might install one. But I'd be interested to hear some other opinions.

Thank you,

Bert

Check with Indmar, most companies don't use oil coolers on the 5.7's

Ayuh,... It's possibly a Good idea, but generally speakin', No,...
Merc don't use motor oil coolers, except on their BBCs, 'n even then, it's the higher output motors...
