Looking at 1976 with Merc Straight 6- I/0

[Jrodnj]

Tomorrow I am going to look at a 1976 V20. Boat is equipped with the Mercruiser Straight 6. I believe it is a 3.0 liter motor. What are some areas to look at with this motor? What outdrive is it hooked up to? Also, owner says Outdrive tilts up but won't tilt back down and claims it is a switch as 1 motor operates the tilt both ways.

Any insight or advice would be greatly appreciated. Worth getting started with or should I run from this motor/outdrive?
